the usual sexual différences. The head (see fig. 10) has the 

 occipital projection, as in the male, remarkably short and obtus- 

 angular, and the ocular region is distinctly protuberant. The 

 rostral part, on the other hand, as is also the case in the 

 female of L. siliqua^ is comparatively shorter and more tri- 

 angular in form, with the apical spine procurved, whereas in 

 the male it is more deflexed (see fig. 3). 



The antennulæ (see fig. 10) are comparatively shorter 

 than in the male, whereas the antennæ and oral parts are 

 of exactly the same structure. 



The 2 anterior pairs of legs are not prehensile, and re- 

 semble in structure the next succeeding ones. In all the 

 legs the lobular character of the distal part of the exopodite 

 is as distinct as in the male, and the relative . size of the 

 epipodite in the several pairs is also much the same, The 

 10th and 11th pairs, as in the female of the type species, 

 are distinguished by the peculiar transformation of the dorsal 

 lappet of the exopodites in thick, sausage-shaped appendages 

 (see fig. 11), the purpose of which is to keep the egg-masses 

 in place. 



The caudal piece does not exhibit any appreciable dif- 

 ference from that in the male. 



Occurrence. — The specimens in the collection of Prof. 

 Henderson are from 2 different localities. From one of 

 these, only adult male specimens were procured. They were 

 taken in May, 1896, by Mr. Slater, from a rain-pool on a 

 hill N.W. of Kadur (Mysore). The other considerably 

 smaller specimens, among which was the above-described 

 female, were collected at Sholinghur, North Arcot District, 

 likewise in a rain-pool.
