The species is new to the Red Sea, it has hitherto been recorded only frou 
the Malabar coast in 29 fathoms by Alcock. 
It has in many of its characters a suspicious resemblance to Cryptodromia 
granulata, the Hpidromia granulata of Kossmann (Kossmann, 1880, p. 69 ; 
and Nobili, loc. cit.). The two species are evidently, as pointed out by Nobili, 
very closely related, but, though it is possible that they may come later to be 
regarded as one, the published evidence yet available does not in my view 
warrant one in uniting them. It may be that there is little difference beyond 
the form of the front, but this is markedly different. In Alcock’s species the 
lateral frontal teeth are much longer and the supraorbital border more 
oblique. I have not had the opportunity of examining the type-specimens.

C.b., is measured immediately in front of the clypeiform expansions ; C.b.. is measured 
across the clypeiform expansions, from tip to tip of the fourth pair of teeth. 
The specimens agree very well with Alcock’s description. The emargina- 
tion of the front is in all the specimens but slightly evident. The measure- 
ments given above indicate growth-change in the ¢ in regard to the ratio
