or pronged right spicule in the male. C. dumerilii (Perrier, 1871), as also the C. dumerilii, Perrier of v. 

 Linstow, 1897 and 1909, and consequently the C. confusus of Railliet and Henry (1915), are probably 

 all synonymous with C. microcephalus. C. tris- 

 pinosus (Leidy, 1851) and C. undulatus, Railliet 

 and Henry, 1915 (= Cucullanus viviparus, v. 

 Linst., 1906, renamed), are so briefly described 

 that it is doubtful whether the species can be 

 identified C. roseus (Leidy, 1851) probably be- 

 longs to another genus. 



Magath (1919) is of the opinion that the G 

 microcephalus of Seurat (1915), from Clemmys 



leprosa, is a different species from C. microce- 

 phalus (Duj.). and proposes for it a new name, C . 

 seuraii. He considers it questionable whether 

 any form can be identified from Dujardin's 

 description, and yet appears to find in the two 

 descriptions sufficient grounds for concluding 

 that the species are distinct. Such discrepancies 

 as there are in these descriptions, however, are 

 in matters of measurement, and it is clear that t Fl ?- 59—Gamallanus kachugae. Vulvar region of

Host: Banded krait (Bungarus fasciatus). 



The buccal apparatus in this species differs somewhat from that typical for the 

 genus Camallanus. The paired valves, on superficial examination, appear to be 

 represented by four separate masses of brown chitin. Actually, these are joined 

 together in lateral pairs by relatively thin plates on their inner surfaces, so that they 

 are really pronounced external thickenings of the usual buccal valves. The usual 

 rib-like structures, terminating in tooth- like projections anteriorly, are present on 

 each inner plate to the number of about 14. The "tridents'' are represented bv 

 simple chitinoid rods of rather irregular shape and of a yellow colour. These are 

 connected at their bases with a dorsal and a ventral chitinoid body, lying opposite to 

 the edges of the buccal valves. 



The male measures 5 - 8-6*6 mm. in length and 0-21-0-25 mm. in thickness. The 

 female is more than twice as large (i^'2-iyy mm. long and 0-4-0-47 mm. in maximum 

 thickness). The cuticular striations are very fine and indistinct, at intervals of about 

 3-4 fi. The diameter of the head, measured dorso-ventrally at the anterior corners, 

 is o oS-O'OO, mm. in the male, 0-12-013 mm. in the female. There appear to be three 

 pairs of cephalic papillae. The measurements of the buccal valves are : length,
