A SMALL TRIBE PA i 
CHAPTER XV 
TRIBE V.—STENOPIDEA 
THE carapace is produced to a laterally compressed ros- 
trum. ‘The first antenne have two flagella, the second 
have a scale. The mandibles have a three-jointed palp. 
The exopod of the third maxillipeds is small, slender, and 
almost rudimentary. The first three pairs of trunk-legs 
are chelate, the third pair being the longest and largest. 
The branchiz are filamentous; only the second maxillipeds 
have a podobranchial plume ; the hindmost pleurobranchial 
plume is the largest. The first pair of pleopods is one- 
branched and foliaceous ; the uropods and telson have no 
transverse suture. 
Family Stenopide. 
This being the only family has the characters of the 
tribe. It contains two genera long included among the 
Penzeid, with which they agree in having the third pair 
of trunk-legs larger than the two preceding pairs, but sepa- 
rated from that group by the structure of the branchize. 
Of the third genus now transferred to this family, the 
branchize have not been described. 
Stendpus, Latreille (¢n Desmarest), 1825, has a long, 
flat, obtusely pointed scale on the second antenne, the 
third trunk-legs long and slender, the fourth and fifth pairs 
with the antepenultimate joint subdivided, the telson taper- 
ing. The genus ranges from the eastern to the western 
hemisphere and from the Arctic regions to the tropics. 
Stenopus hispidus (Olivier) is recorded from the Pacific, 
from Bermudas, and perhaps from Greenland. Spence 
Bate’s figures of this species are reproduced on a re-
