On some Indian Phyllopoda. 



The trunk, or mesosome, consists of 11 segments, each 

 carrying a pair of branchial legs. The segments are quite 

 simple, and very uniform both as to size and form, the 

 width being about the same as the height. 



The genital region in both sexes is composed of 2 partly 

 coalesced segments, and is somewhat larger in the female 

 than in the male, in the former about equalling the 3 pre- 

 ceding segments combined. In the female this region is im- 

 mediately continued below into the marsupial pouch (see 

 fig. 1), which extends posteriorly along the ventral side of 

 the caudal part, reaching about to the end of its antepen- 

 ultimate segment. It is rather narrow, conically tapering 

 distally, and, as usual, terminates in 2 unequal beak-like lips, 

 neither of which is abruptly bent. Within the marsupial pouch, 

 numerous dark-coloured ova are accumulated, and in its 

 proximal part, the richly ramified glutinous gland may more- 

 over be traced, partly concealing the ova in that part. In 

 the male (fig. 2) this pouch is replaced by 2 comparatively 

 small, juxtaposed, cylindrical processes containing the outer 

 part of the seminal duct, which in one case was evaginated 

 in the form of a thread-like appendage clothed with small 

 recurved spikes. 



The caudal part, or tail proper, in both sexes is cylindric 

 in form and shghtly tapering distally, and is composed of 

 7 segments, the penultimate one being somewhat longer than 

 the preceding ones. The last segment is rather short and 

 somewhat produced at the end, between the insertions of 

 the caudal rami (see fig. 10). In the female (fig. 1) this 

 section is considerably shorter than in the male, scarcely ex- 

 ceeding Ys of the length of the body, whereas in the male 

 (fig. 2) it is fully as long as the trunk. 



The caudal rami are of essentially the same appearance
