carapace, and its slightly rugose outline when viewed from above; this rugosity is 
due to the fact that the thickened margins of the reticulations are particularly pro- 
minent on the middle of the sides. Further, in both pinguis and globosa the in- 
tegument is much less calcified, with the reticulation sharply defined, the pleon 
is more slender, the spines of the second peraeopods are longer, ete. 
C. pusilla Sars apparently also has very feeble, articular abdominal pegs; 
Sars (1887, p. 19) does not indicate them at all in his figures 21 and 22. 
CYCLASPIS PINGUIS Sp. nov. 
Ovigerous female. Integument indurated, with clear-cut coarse reticulations, 
larger than in globosa (cf. F, fig. 26 and 30). 
Carapace subglobose, strongly arched from back to front and from side to 
side; ovoid in shape as seen from above, tapering slightly to the front and widest 
at middle of length, where it is distinctly broader than deep; depth more than

two-thirds of length. Antennal notch deep and rather narrow; antennal tooth 
acute. Ocular lobe as in clarki and globosa. Pseudorostral lobes just meeting in 
front and narrowly truncate anteriorly. 
A dorsal carina runs for whole length of carapace, pedigerous somites and 
pleon ; it is very distinct but very fine; structurally it is formed by the arrange- 
ment end to end, in a median longitudinal line, of the raised margins of the reticu- 
lations (fig. 30, F). 
Five pedigerous somites are exposed, the first being short; together they are 
more than two-thirds as long as carapace; second expanded laterally, where it is 
almost as long as third to fifth combined, and with dorsal margin, seen from the 
side, continuing the even curve of the carapace. 
Pleon slender, and flexible, with feeble articular pegs; each somite subeylindri- 
eal; first to fourth and telsonic somites subequal in length; fifth about half as long 
again as any one of them.
