CRrYPTODROMIA MONODOUS, sp. nov. Plate VITI. 
The carapace has a depressed, but apically slightly up-turned, tooth 
in front. To the solitariness of this the specific name refers. Instead 
of the usual flanking teeth there is on either side a convex prominence 
constituting the upper border of the orbit. The general surface of 
the carapace is quite devoid of grooves, finely punctate, with a short 
pubescence ; the antero-lateral border on the right showing eight teeth 
or tubercles, the two preceding the hindmost very small and without 
counterparts on the left side. Apart from the rostral depression and 
depressions adjoining the postero-lateral margins, on which the fifth 
peropods rest, the carapace is much inflated, and this character with 
the strong convexity of the pleon gives the whole structure a globose 
appearance, |
