“…The possibility that the rearrangement of the NLD in haplorhines is associated with a reduced emphasis on vomerolfaction receives some support, by analogy, from recent research on Microchiroptera (Göbbel, 2002).…”

“…A functioning VNO combined with a narial opening of the NLD appears to be the plesiomorphic state among chiropterans (as in primates), but both elements have been transformed in various microchiropteran lineages (Wible & Bhatnagar, 1996;Göbbel, 2002). The anterior portion of the NLD has been reduced in at least four microchiropteran lineages (Göbbel, 2002). In some, the result is a meatal opening near the level of the NPD (e.g.…”

“…Reconstructing the sequence of changes in VNO morphology in such a speciose order is complicated by sampling issues (see Wible & Bhatnagar, 1996), and attempting to associate these changes with those in the NLD system is necessarily tenuous. Nonetheless, it is notable that all four clades in which the NLD is truncated also undergo either loss of neuroepithelia from the VNO or complete loss of the VNO (Wible & Bhatnagar, 1996;Göbbel, 2002). In some of these groups, the nasolacrimal duct is reduced (e.g.…”

“…This anterior position of the NLD opening was referred to by Starck (1960) as a 'primary' opening, because it is clearly plesiomorphic, and was contrasted with a 'secondary' position of the opening (described below). Herein, we employ the terms 'narial' (primary) and 'meatal' (secondary), following Göbbel (2002).…”

The ontogeny of the nasolacrimal ducts (NLD) and canals (NLC) are investigated in strepsirrhine and haplorhine primates. Developmental series of serially sectioned fetal, perinatal and adult specimens, in combination with juvenile and adult skulls subjected to high-resolution computed tomography, reveal that the vertical NLC and NLD of adult tarsiers and anthropoids are produced by the degeneration of a more horizontal anterior arm of the NLD that is present only transiently in haplorhines, but is maintained throughout life in strepsirrhines. This degeneration manifests as an 'unzipping' of the anterior arm by means of progressive enlargement (in a rostral direction) of a caudally placed opening of the NLD (at the base of the vertical NLC), followed by breakdown of the resulting epithelial groove. The similar mode by which the anterior arm of the membranous NLD degenerates in tarsiers and anthropoids strongly suggests that the conditions in these two taxa are homologous, and provides additional evidence for a monophyletic Haplorhini. The functional relationship between the nasolacrimal duct and the vomeronasal organ is reviewed in light of this evidence, and it is suggested that these changes in the haplorhine NLD were functionally linked to the development of anatomical haplorhinism of the oronasal complex.

“…Consequently, careful histological examination is needed before the presence or absence of this gland in bats is deduced. Considerably more is known about the NLD (Göbbel,2002) and the VNO (Cooper and Bhatnagar,1976; Wible and Bhatnagar,1996) of bats.…”

The facial glands of bats are modified skin glands, whereas there are up to three different orbital glands: Harderian, lacrimal, and Meibomian glands. Scattered studies have described the lacrimal and Meibomian glands in a handful of bat species, but there is as yet no description of a Harderian gland in bats. In this study we examined serial sections of orbitofacial glands in eight families of bats. Much variation amongst species was observed, with few phylogenetic patterns emerging. Enlarged facial glands, either sudoriparous (five genera) or sebaceous (vespertilionids only) were observed. Meibomian and lacrimal glands were present in most species examined (except Antrozous), though the relative level of development varied. Two types of anterior orbital glands were distinguished: the Harderian gland (tubulo-acinar: observed in Rousettus, Atribeus, Desmodus and Miniopterus) and caruncular (sebaceous: observed in Eptesicus and Dieamus). The relative development of the nasolacrimal duct and the vomeronasal organ did not appear to be correlated with the development of any of the exocrine glands examined. There does, however, appear to be a correlation between the presence of at least one well developed exocrine gland and the level of communality and known olfactory acuity, best documented in Artibeus, Desmodus, and Miniopterus.

The nasolacrimal apparatus (NLA) is a multicomponent functional system comprised of multiple orbital glands (up to four larger multicellular exocrine structures), a nasal chemosensory structure (vomeronasal organ: VNO), and a connecting duct (nasolacrimal duct: NLD). Although this system has been described in all tetrapod vertebrate lineages, albeit not always with all three main components present, considerably less is known about its ontogeny. The Mongolian gerbil (Meriones unguiculatus) is a common lab rodent in which the individual components of the adult NLA have been well studied, but as yet nothing is known about the ontogeny of the NLA. In this study, serial sections of 15 fetal and three adult Mongolian gerbil heads show that the development of the NLA falls into three fetal stages: inception (origin of all features), elongation (lengthening of all features), and expansion (widening of all features). No postnatal or juvenile specimens were observed in this study, but considerable growth evidently occurs before the final adult condition is reached. The development of the orbital glands and the VNO in the Mongolian gerbil is largely consistent with those in other mammals, despite a slight nomenclatural conundrum for the anterior orbital glands. However, the Mongolian gerbil NLD follows a more circuitous route than in other tetrapods, due mainly to the convoluted arrangement of the narial cartilages, the development of a pair of enlarged incisors as well as an enlarged infraorbital foramen. The impact of these associated features on the ontogeny and phylogeny of the NLA could be examined through the approach of network science. This approach allows for the incorporation of adaptations to specific lifestyles as potential explanations for the variation observed in the NLA across different tetrapod clades.
