I refer to this species nine specimens obtained by Mr. F. H. Townsend in the 

 Gulf of Oman and the Persian Gulf. The largest is only 108 mm. in total length and 

 is consequently much smaller than Kossmann' s type (140 mm.). 



Squilla massavensis is evidently an extremely close ally of 5. wood-masoni and 

 like that species may be distinguished from 5. oratorio, and S. interrupta by the dac- 

 tylus of the raptorial claw (see Balss, 1910, text-fig. 3), which is strongly sinuous 

 externally and provided with short teeth, while other less conspicuous characters are 

 the size of the cornea — the corneal index is about the same as in 5. wood-masoni — 

 the deep-cut cervical groove and the extreme reduction in size of the lobe on the 

 outer aspect of the longer of the two spines forming the basal process of the uropod. 



From S. wood-masoni the species may be distinguished by the following char- 

 acters : — 



1. The dorsal surfaces of the carapace and abdomen do not present a polished 

 appearance. 



1 The specimen was identified prior to the examination of a series of S. massavensis. It is not im- 

 probable that it should more properly be referred to that species.
