1913-] S. Kkmp : Crustacea Stomatopoda of the Indo-Pacific Region. 27 



The colour of spirit specimens is not very striking. The posterior margins of the 

 carapace and of the last three thoracic and first five abdominal somites are narrowly 

 bordered with black pigment and frequently a small black spot is visible on the dorsal 

 surface of the eyestalk, touching the cornea. 



The eight specimens in the Indian Museum are registered as follows :—

This species may be readily distinguished from the preceding by the following 

 characters : — 



1. The lateral process of the fifth thoracic somite consists of a long and sharp spine 



which is strongly bent forwards (fig. 14). 



2. The inferior margin of the same somite bears on either side a small acute tooth. 



3. The lateral margin of the seventh somite is rounded behind, but in front is 



produced as a sharp spine (fig. 14). 



4. The inferior surface of the telson bears a number of short carinae, which are 



more or less broken up into tubercles, on either side of the well-marked 

 post-anal carina (fig. 16). 



The rostrum is short, much wider than long, and its upturned lateral margins 

 converge to a broadly-rounded apex. The eyes (fig. 13) are similar to those of 5. lat- 

 reillei, but the stalk is rather less swollen ; the inner margins are flattened and in 

 juxtaposition for about three-quarters of their basal length. There is a three-segmented 

 mandibular palp. The raptorial claw also resembles that of the preceding species ; in 

 all the specimens examined the dactylus bears five teeth and the proximal tooth is well 

 separated from the next of the series. 



The lateral process on the anterior part of the eighth thoracic somite is sharply
