Pleon with a median longitudinal carina for whole length; each of the first 
to fourth somites have six tiny projections at the hinder margin; two are on the 
dorsum, close together, while there is on each side a dorso-lateral projection larger 
than the dorsal ones, and one immediately above each articular peg. 
First antennae with first segment of peduncle distinctly longer than all the 
other joints together; second segment as long as third peduncular joint plus the 
first of the two segments of the flagellum, which bears the usual two filiform ter- 
minal appendages. 

Fig. 57. Cyclaspis sabulosa, type female; A, lateral view of whole animal and B, of anterior 
portion of carapace; C, cephalothorax from above (A and C, X 16; B, X 40). 
Third maxillipeds with outer apical portions of basis and merus expanded 
and produced forwards and with the anterior margins spinose; carpus spinose on 
apical and inner edges, as wide as long and longer than either propodus or dac- 
tylus. 
i In the first peraeopods the basis is equal in length to the remaining segments 
together ; it bears a plumose seta at outer apical angle and has the margins spinose ; 
carpus stout, with spinose edges, shorter than the much more slender propodus 
and more than twice as long as the dactylus, which is unusually short, as are its 
terminal setae (fig. 56, C). 
Basis of second peraeopods much longer than rest of limb; merus little longer 
than carpus, but nearly twice as long as the short and stout dactylus, which is a 
little shorter than its longest terminal spine. 
Basis of third and fourth peraeopods longer than rest of limb, that of fifth 
shorter; merus shorter than carpus in third and fourth, subequal in fifth; setae 
sparse and short (see fig. 3, C).
