Fig. 36. Cyclaspis tribulis, ovigerous female; A, B and ©, carapace from side, front and 
above; D, first peraeopod; E, telsonic somite and uropod. F, Carapace of a ‘‘spiny’’ non-ovigerous 
female. Lateral views of G, cephalothorax and H, telsonie somite and uropod of juvenile; H1, 
apices of rami of uropod (A to O, X 84; D and F, X 12; H, X 20; G and H, X 34; H1, x 145). 
the side the dorsal margin is only slightly elevated posteriorly, thence a little 
convex to base of ocular lobe, where there is a marked tumidity (p.o.t.); each 
antero-lateral area immediately behind pseudorostral lobes expanded laterally 
(so that in dorsal view the carapace is widest here) and with two confluent tumi- 
dities armed with conical tubercles; pseudorostral lobes with short elevated 
ridges ; sides of carapace with coarse reticulations and a few short ridges.
