propodus. Also, this peracopod is here as long as the second leg, whereas in typi- 
eal inales (seemingly fully adult, and with long setae on the thoracic exopods) if 
is mueh shorter than that limb and has the carpus only about half as long agai 
as propodns, As noted elsewhere, the attainment of complete sexnal maturit y by 
the male of some other Cumaven results in considerable changes and one may 
venture to suspect in this ease the possibility of two forms of this sex, both ap- 
parently adult; this assumption, however, shonld be viewed with caution and there 
is the possibility that the long-legged male represents another species, 
CUMBLLA TURGIDULA sp. nov. 
Adult male, Integument of back and sides granulate, the granules rather more 
conspicuous on pedigerous somites than on carapace, and clothed with short vel- 
low hairs which become sparser on the pleon, 

Fig. 19. Gwmella turgidula, lateral view and dorsal view of cephalothorax of type male 
(xX 23), 
Carapace not quite one-third of total length of animal ; a little depressed aud 
nearly twice as long as deep; seen from above it tapers towards the front and is 
widest across the branchial regions which are somewhat inflated; there is a low, 
median carina, interrupted between the branchial tumidities by a short broad fur- 
tow; at the posterior end of each pseudorostral suture there is a smal! boss; seen 
from the side the pseudorostrum is not upturned, its coneave upper margin enry- 
ing back and up to above the eye; thence the dorsal contour is arched, with « de- 
pression behind middle of length, posterior to which is a low hinder tumidity. 
Anterolateral margin shallowly concave and antero-lateral corner rounded, ob- 
tusely-angular. Psendorostral lobes moeting in front for a distance equal to fully 
half length of ocular lobe; anteriorly they are subaente, crenulate, with a few 
setae and seen from the side very oblique. Ocular lobe wider than long, with seven 
large corneal lenses, one pair colourless, the others black. 
Virst pedigerous somite exposed above, concealed on lower part of side by the 
anterior pleural lobe of second; third to fifth with pleural parts expanded and 
slightly backwardly produced ; second almost as wide as carapace and, like the 
third, with a faint median carina, 
First four pleon somites subequal in length, each distinctly shorter than 
the tifth, which is narrow, twice as long as wide; telsonie somite almost as lone as 
fifth, less than twice as long as wide, scarcely dilated posteriorly, produced above 
bases of uropods where it is rounded with a small median terminal point: baek of 
all somites rounded without traee of median ridge,
