294 MR. A, O. WALKER ON THE 
member dentate, is its nearest ally. The absence of a palp to the 
mandibles will probably require the formation of a new geuus 
when the male is taken. 
LEpPTOMyYsIS APIoPS, Sars. 
St. 5. Three or four. 
DIaMYSIs BAHIRENSIS (Sars). 
St. 1, 6. Two or three young. 
CUMACEA. 
CuMA scORPIOIDES (MMont.). 
St. 2. Two males, two females, all immature. Length 4mm. 
CuMA PULCHELLA, Sars. 
St.1. One young female. Length 2 mm. 
IpHinor serrata, Norman. 
St. 3, 5, 6. 
The commonest Cumacean at Cannes: all the specimens were 
immature. This is now considered by G. O. Sars to be distinet 
from JI. trispinosa (Goodsir), of which he formerly believed it to 
be a mere variety (Crust. of Norway, vol. 11. p. 14). 
CYCLASPOIDES CORNIGERA (Sars). 
St. 3. Four specimens. 
DiasTyLis RuGOSA, Sars. 
St. 3, 5, 6. Several. 
DIASTYLOIDES BIPLICATA, Sars. 
St. 8, 5, 6. Five specimens. Length 3:25 mm. 
None of the specimens had more than 4 marginal spines on 
the telson instead of 12: this is probably a condition of im- 
maturity. 
PSEUDOCUMA CERCARIA (v. Beneden). 
St. 6,24. Two specimens. 
CUMELLA PYGM#A, Sars. 
St. 6. One female. St. 2H. One male. 
NANNASTACUS LONGIROSTRIS, Sars. 
St, 2”. One female.
