A new echinostome cercaria, Cercaria kuwaitae XI sp.n., from the prosobranch gastropod Cerithidea cingulata (Gmelin) from Kuwait Bay is described. The new cercaria is characterized by 23 collar spines and primary excretory tubules with distinct diverticula. The cercaria encysts in the snail host and is similar to those of Acanthoparyphium sp. The surface topography of the redia, cercaria and metacercarial cyst wall is studied by scanning electron microscopy. This is the first echinostome cercaria to be recorded in a gastropod from the Arabian Gulf region.Key words: Digenea -Cercaria kuwaitae XI sp.n. -Acanthoparyphium sp. -ultrastructure -Cerithidea cingulataKuwait Bay alcohol (AFA) and staining in acetocarmine. Measurements are in micrometres, the range with the mean in parentheses, and were taken from 20 vitally stained refrigerated specimens. Figures were drawn with the aid of a camera lucida from vitally stained specimens. For SEM, living larval stages were fixed in a solution containing 4% formaldehyde and 1% glutaraldehyde in 0.1 M phosphate buffer (pH 7.2) at 4°C. Following the appropriate buffer wash, the specimens were post-fixed in 1% osmium tetroxide in the same buffer for 5 min at 4°C, dehydrated in a series of anhydrous acetone and critical-point dried. The specimens were coated with gold and then examined in a Jeol JSM-6300 scanning electron microscope.

“…Although several species have been reported (Yamaguti 1934;Ching 1961;Nollen & Murray 1978;Radev, Kanev & Gold 2000) the family is typified by the species, Philophthalmus gralli, commonly known as the "oriental eye-fluke".…”

A total of 17 commercially reared ostriches (Struthio camelus) from Msengi farm, Chinhoyi, Zimbabwe, observed with swollen eyes, severe conjunctivitis and constant lacrimation accompanied by a purulent exudate, were restrained for further clinical examination. Some of the birds were semi-blind with severe loss of body condition. When examined, tiny organisms were observed attached to the nictitating membranes and the conjuctival sacs of both eyes. The organisms were identified as Philophthalmus gralli, the "oriental eye-fluke" and Melanoides tuberculata, a prosobranch snail, was confirmed as the intermediate host through natural and experimental infection. To the best of our knowledge this is the first record of the oriental eye-fluke infection in birds in Zimbabwe and Africa and extends its known geographical range.

“…These variations are of particular interest since the trilobed nature of the germarium was one of the principal distinguishing features of a new species, P. major Yamaguti, 1934, and the vesicula seminalis partially external to the cirrus sac was the only specific feature of P. insolitus (Nicoll, 1915) Dollfus, 1952 (syn: Xenopera insolita1). These two species must, therefore, now be considered synonymous with P. subtenuis.…”

Experimental Infection of Two Species of Wrasse With The Digenean Proctoeces Subtenuis

Uzmann (1959), and by Uzmann (1953). P. subtenuis has usually been recorded from the hind-gut oflabrid and sparid fishes in tropical and subtropical seas, and Freeman & Llewellyn suggested that the occurrence of adult forms of the parasite in an invertebrate host was probably abnormal, and that the more normal life cycle includes a vertebrate as the definitive host. In Britain P. subtenuis has never been recorded from a fish, and so it has not been possible to make a direct comparison of specimens from an invertebrate with specimens from a vertebrate. It was therefore decided to attempt to infect suitable British fishes with specimens of P. subtenuis obtained from S. plana, and to compare any surviving parasites from these fishes with others collected directly from the mollusc. MATERIALS AND METHODSThe fishes used in the experiments were the only two labrids available in sufficiently large numbers in the Plymouth area, the two wrasse species Ctenolabrus rupestris (L.) and Crenilabrus melops (L.). A total of 35 wrasse was used, the fishes being divided into two groups. Those of the first group of 18 (10 C. rupestris and 8 C. melops) were killed and their alimentary canals examined. Many of them were found to contain adult digeneans belonging to the family Allocreadiidae, as had been recorded previously by Nicoll (1910, 1914), and one of them had two unidentified metacercariae encysted in the peritoneal fat, but not one of them contained a single specimen of P. subtenuis. It was therefore assumed that the remaining 17 wrasse (7 C. rupestris and 10 C. melops) to be used in subsequent experiments were free from naturally occurring P. subtenuis. These 17 specimens of wrasse varied in length between 10 and 20 em. The sizes of the fishes in which P. subtenuis 8
