long as second, with a short inner spine at distal end; second joint with two inner 
spines and with terminal spine rather slender, longer than the ramus; exopod with 
terminal spine longer than the ramus, but shorter than that of endpod. 
Colour cream. Length 2-2 mm. 
Adult male. Carapace more than one-third of total length of animal, nearly 
twice as long as pedigerous somites together and three-fourths as long again as 

Fig. 6, Gynodiastylis lata, type female and paratype male; ant., first antenna. (x 125; 
flagella, % 250); mxp. and prp., third maxilliped and first to third peraeopods ( 125); urop., 
uropod with sixth pleon somite and telson (X 125). A. urop., Uropod of male of @, turgida for 
comparison (X 125), 
its depth, which is equal to about four-fifths its greatest breadth; seen from above 
it is subrectangular ; disposition of ridges much as in female. Antero-lateral mar- 
gin and ‘‘angle’’ rounded, without trace of tooth. Pseudorostral lobes stouter 
and shorter than in female, subtruncate in front as viewed from above. Ocular 
lobe twice as wide as long, with three oval pale areas, apical and lateral, apparently 
representing the eyes. 
Pedigerous somites successively increasing in dorsal length; first somite ex- 
posed only dorsally and dorso-laterally; second overlapped by pleural part of 
third, which also overlaps fourth to the rear; fourth and fifth with pleural parts 
expanded backwards; second iv fifth each with a dorso-lateral ridge on each side. 
Pleon much as in female, with distal somites of same proportions, 
Well developed exopods (with peduncle not very wide, however) on third
