3o Records of the Indian Museum. [Vol. X, 1914.] 



Inner uropods one and three (quarters as long as the telson, 

 without spines on its inner margins; otocyst rather large. 



Outer uropods twice as long as the telson 



First, second and third pleopods in the male similar to those 

 of the female; fourth pleopods (Sg. 11) distinctly biramous, 

 inner ramus quite small and armed with a few slender setae ; outer 

 ramus extending beyond the posterior end of the last segment of 

 the pleon, consisting of a single joint terminated b}' a very long 

 stout spiniform seta; fifth pleopods (fig. 12) elongate, reaching 

 backwards as far as the outer ramus of the fourth pair, consisting 

 of a single joint armed at the distal end with about four very 

 long and slender setae. 



Marsupial pouch of the female, composed of two pairs of 

 lamellae 



Locality. Brackish creek at Panvel, near Bombay, February, 

 191 1 (/. Caunter). About two hundred specimens up to 7 mm. 

 in length. 



I dedicate the species to Dr. Annandale, the Superintendent 

 of the Indian Museum, who has done so much to elucidate the 

 brackish water fauna of India. I have not seen any specimens from 

 any other locality in India 



This species differs from all other members of the sub-family 

 INIysinae in the form of the pleopods of the male and the elongate 

 form of the fifth pleopods necessitates a modification of the defini- 

 tion of the sub-family in order that this species may be included. 

 The pseudochelate appearance of the sixth and seventh thoracic 

 limbs, and the peculiar form of the extremity of the eighth 

 thoracic limbs are quite characteristic and unknown to me in any 

 other species.
