Fig. 20. Cumella turgidula, type male; ant. 1, first antenna (% 45; last peduneular joint 
and flagella, x 160); prp., peraeopods (% 45); urop., uropod (XX 86); with fifth pleon and 
telsonie somites (x 45). 
Fifth peraeopods with carpus more elongate than in preceding legs, nearly 
three times as long as merus and three-fourths as long again as propodus. 
Pedunele of uropod equal in length to telsonie somite and barely longer than 
endopod, inclusive of its terminal spine; its inner margin is spinulose and is armed 
with six large spaced spines, successively decreasing in length towards the rear ; 
exopod three-fourths as long as endopod, and as long as its stout termimal spine ; 
endopod with six spines, equal in size, on inner margin and with a robust distal 
spine more than half as long as the ramus. 
Colour: evenly shaded with brown excepting for the anterior part. of eara- 
pace (where the colour merges into dark umber) and a pale yellow edging at mar- 
gins of carapace and anterior and posterior edges of somites. First antennae
