and not of fera. The fifth legs of a fera male are seen in figure 414 
and may be identified by the three fingerlike processes on the hand of 
the chela of the right leg. One of these is near the base of the 
movable finger, and the other two are at the opposite end of the 
hand, and when the chela is closed the finger shuts down between 
them. These last two are unequal in length; the longer one is blunt 
at its tip and transversely wrinkled, the shorter one smooth and acute. 
Behind these two processes on what might be termed the wrist of the 
hand is a circular lamina projecting outward and sidewise. 
PONTELLA GRACILIS, new species

Station 5223. Five females were found in the plankton at this 
station between the islands of Luzén and Marinduque in the Philip- 
pines in a surface tow. 
Female.—Metasome elongate elliptical, three and a half times as 
long as wide and narrowed but very little at each end. Head conically 
rounded in front, with well-defined lateral hooks; rostrum very large 
for so small a copepod and bifurcate to the very base, the branches 
acuminate. Fourth and fifth segments fused, the posterior corners 
bluntly rounded and reaching the center of the genital segment. Uro- 
some half as wide and, without the caudal rami, less than a third 
as long as the metasome and 3-segmented. The anal segment is the 
longest and the middle segment the shortest, and all three are about 
the same width. The caudal rami are twice as long as wide but are 
much shorter than the anal segment, and are somewhat divergent. 
The first antennae do not quite reach the urosome and are rather 
slender and sparsely setose. The endopod of the second antenna is 
3-segmented, and the exopod just reaches its tip. The fifth legs are 
unlike those of other species in the genus; the two basipod segments 
are much swollen, the second one diagonally cut at the inner corner 
for the attachment of the endopod. The latter is conical, half as long 
as the exopod, and bluntly rounded at its tip without bifurcation. 
The exopod is twice the width of the endopod at its base and is nar- 
rowed distally and obliquely truncated at its tip, with a short acute 
spine at each corner. Total length 2mm. Metasome 1.70 mm. long. 
Types.—U.S.N.M. No. 74131; station 5223, latitude 13°36’ N., longi- 
tude 121°25’30” E., off Santa Cruz, Philippine Islands. 
Remarks.—This species may be recognized by its minute size, its 
short first antennae, and the details of the fifth legs.
