and still less easily discernible ridge; below the posterior portion of each pseudo- 
rostral suture are two confluent anterolateral tubercles, one below the other; the 
carapace is widest across the lower of these tumidities. Pseudorostral lobes not 
meeting in front of ocular lobe. Antennal notch wide and shallow; angle some- 
what obtuse, with a small oval tumidity behind it. Ocular lobe narrow, with a 
mulberry-like mass of prominent, pigmented lenses at anterior end.

Pig. 54. Cyclaspix munda, type male; A, third maxilliped; B, C, D and E, first, second, 
fourth and fifth peraeopods; F, fifth pieon and telsonie somites, and uropod; M4, terminal half 
of rami of uropod (A, B, D, E and F, X% 32; C and F1, * 80). 

Pedigerous somites two and five with a median carina which is produced as 
a little tubercle at posterior margins; fourth with a very faintly marked, double 
median ridge, nol produced at hinder edge; third short dorsally, not carinate. 
Sides of pleon somites, unlike leg-bearing ones, tumid fore and aft when seen 
from above; first to fourth somites each with a median ridge, evanescent an- 
teriorly but slightly produced at hinder end of somite; fifth with a median earina 
on posterior third, bifureating anteriorly to form a pair of divergent dorso-lateral 
earinae; telsonic somite with a low carina, ending abruptly at two-thirds of length, 
un incision in the dorsal outline at its termination. 
Third maxillipeds with basis and merns produced and widened apically to 
form prominent lobes; carpus longer than propodus or dactylus. 
First peraeopods slender ; basis longer than rest of limb, and with two apical 
plimose setae; carpus a little shorter than propodus, and as long as the narrow 
dactylus, which is shorter than its longest terminal seta. 
Basis of second peraeopods not as long as remaining segments together ; merus
