Studies on Indian Rhynchobdellid leeches. I

Abstract

Our knowledge of the Indian Rhynchobdellid leeches is still in its infancy, and the little that we have, we owe to the researches of Harding, Kaburaki, and Moore. After the publication of the Hirudinea volume by Harding & Moore (1927) in the Fauna of British India Series, Bhatia (1930a, b, 1934, 1939), Chelladurai (1934) and Raj (1951, 1954a, b) have contributed to the systematics of this group. The present work has been undertaken with a view to advancing further our knowledge of Indian Rhynchobdellid leeches. In this work, the neurosomic theory of somite limits launched independently by Castle (1900) and Moore (1900) has been followed in counting the annular composition of somites. This paper, the first of the series, deals with the description of four Glossiphonid leeches, of which three are new to science, while the fourth one is of zoogeographical importance.

Redescription of Hemiclepsis quadrata (Moore, 1939) n. comb. (Hirudinea: Glossiphoniidae)

“…There is one species (H. hubeiensis Yang, 1981) with one pair of eyes, two species (H. marginata (Miiller, 1774) and H. japonica (Oka, 1932)) with two pairs of eyes and four species (H. viridis Chelladurai, 1934, H. quadrata, H. bhatiai Baugh, 1960and H. erhaiensis Yang, 1981 Baugh (1960) states that H. bhatiai has nine pairs of crop caeca but he adds (p. 293): 'A pair of very small lateral inflations (probably oesophageal organs) of the crop-stomach is also distinguishable in the region between the second and the third pair of caeca'. There is one species (H. hubeiensis Yang, 1981) with one pair of eyes, two species (H. marginata (Miiller, 1774) and H. japonica (Oka, 1932)) with two pairs of eyes and four species (H. viridis Chelladurai, 1934, H. quadrata, H. bhatiai Baugh, 1960and H. erhaiensis Yang, 1981 Baugh (1960) states that H. bhatiai has nine pairs of crop caeca but he adds (p. 293): 'A pair of very small lateral inflations (probably oesophageal organs) of the crop-stomach is also distinguishable in the region between the second and the third pair of caeca'.…”

Sublime Cascades: Water and Power in Coalbrookdale

“…62 The Upper Furnace Pool was partially cleared in the late 1970s, 63 but resilting rapidly occurred and by the early of the fabric suggests that this was probably constructed in the second quarter of the 19th century, following the abandonment of the Lower Furnace by the 1820s. 59 There was little remedial construction work required on this part of the system, the main work in this area involving the clearance and 21st century the pool was entirely infi lled. Due to access and other problems it proved impossible to remove the tipped ash from upstream, and so a series of easily maintained silt traps were constructed in Loamhole Dingle during 2003 in order to prevent future resilting.…”
