Cyclaspis caprella Hale, 1936, p. 395, fiz. 1-2. 
Unique becanse of the forwardly directed acute horis at the front of the 
carapace, a feature not found in any other member of the genus Cyclaspis. The 
pair of dorso-lateral elevations on each of the last two pedigerous somites and first. 
pleon somite are also (distinctive, 
Males and subaduli females, taken by townet and submarine lieht, are in hand 
from several localities in Spencer Gulf, where the type male was secured. 
In the adult male, as viewed from the side, the dorsal portion of the anterior 
margin of the second pedigerous somite forms an open V with the upper part of the 
hinder edge of the carapace; the dorso-lateral ‘‘tubercles’’ of the fourth and fifth 
pedigerous somites are acutely triangular and tooth-like; the pair on the first pleon 
somite are obtuse (misprint ‘‘obseure’’ in original description) and subtriangnlar, 
Subadult males and females have only a very small V-shaped dorsal incision 
between the carapace and the second pedigerous somite; the dorso-lateral elevations 
of the last two pedigerous somites are less acute and those of the first pleon somite 
are quite different, having the form of slender, acute, procurved and divergent 
thorns, 
The exopod of the uropod bears two slender apical mucrones of almost equal 
length,
