Genus Iphinoe, Bate (1856). 
(=j Halia, Bate, 1856, in use for genera of Mollusca and Lepidoptera.) 
Animal greatly elongated. Cephalothorax low, narrow, 
compressed, greatly produced, generally having the dorsal 
line of carapace spined in female; rostrum produced; five 
free segments of pereion, the last two subequal, scarcely wider 
or higher than the pleon. Second maxilliped having the basal 
joint longer than the remainder taken together, first and 
second joints distally furnished with a long plumose seta, last 
joint in the form of a strong nail. Third maxilliped having 
the first and third joints produced into very large setiferous 
lobes on the inner distal extremity ; the lobe of the first joint 
reaches at least to the middle or end of the third joint, that of 
the third joint extends to the middle of the fourth joint. 
Pereiopods, only the first, even in the male, furnished with 
palpi; second pair much smaller than usual and more like 
the following pairs. Telson rudimentary, but bilobed. Uro- 
pods strongly developed, both branches two-jointed ; outer 
joint flattened, truncate at the apex. The male has the 
first five segments of pleon furnished with swimming-feet, 
and the spines on the dorsal line of the carapace usually 
(? always in adult) absent. 
This genus was established by Bate (Ann. & Mag. Nat. 
Hist. 1856, 2nd ser. vol. xvii. p. 458) under the name Halia, 
with the Cuma trispinosa , Goodsir, as the type. Subse- 
quently finding that Halia was already in use for a genus of 
Lepidoptera, he changed the name to Iphinoe (Ann. & Mag. 
Nat. Hist. 1856, 2nd ser. vol. xviii. p. 187). 
The members of this genus bear a stinking general resem-
