males, 9-18 mm.; Sacculina infected specimen, 13 mm. 
REMARKsS.—Crosnier’s (1962) identification and redescription of this 
species is based upon comparison with Gordon’s refiguring of Bor- 
radaile’s type, and there are no doubts regarding Stephenson’s (1961a) 
misidentification. 
Male pleopods of the present material (fig. 27) bear fewer subter- 
minal spines than those figured by Crosnier (1962, figs. 175-177) but 
evidently belong to the same species. 
DistripuTION.—Madagascar, Maldive-Laccadive Archipelago.

Remarxs.—Alcock’s brief diagnosis serves to identify this species. 
It resembles 7. investigatoris in its long walking legs and in the form 
of the chelipeds. In these the upper surface bears rounded granules; 
there are no carinae, and only two spines are present on the upper 
surface (including the one at the wrist articulation). The species is 
characterized by the considerable overlap between median and sub- 
median frontal lobes and by the absence of spinules on the posterior 
borders of the propodite of the fifth leg. 
The male abdomen and pleopod appear not to have been described; 
both are highly characteristic. Penultimate segment of abdomen 
with markedly convex lateral borders (fig. 28¢c). Pleopod with re-
