GYNODIASTYLIS BREVIPES 8p, NOV. 
Female with developing marswpium, Tntegument calcified but thin; smooth 
and polished. 
Carapace robust, boldly arched above; it is barely one-third of total length 
of animal, half as long again as pedigerous somites together; one-third as long 
again as deep and a little compressed; on each pseudorostral lobe a short: longi- 
tudinal dorsal ridge runs from apex to ocular lobe and a second curyed carina 
extends from the tip to just below posterior end of frontal lobe; on each side

on ocular lobe, which is armed with a pair of spinules. Antero-lateral margin.

to about one-ninth length of carapace. Frontal lobe well-marked ; ocular lobe very 
short and broad, with three ill-defined oval areas representing the eyes,

expanded in front and (more markedly) posteriorly, aud in fourth backwardly 
produced; seeond and third peraeopods not separated by a very pronounced 
interval ; first to third somites each with a transverse fold; fourth (which is the 
longest dorsally) and fifth (which is not much shorter) each with a pair of strong 
longitudinal dorsal carinae, and with anterior and posterior margins between
