Remarks. This small species is instantly recognized by the long pseudorosl mm, the very few dorsal 

 saw-teeth on the carapace, two pairs oi teeth on the frontal lobe, and the rami of the uropods. In the two 

 first-named features it shows relationsship to /.. spiniventris n. sp., but the latter is much larger and dii 

 from /.. tener in several sharply pronounced features.
