half as long as the endopod, which is stout and 3-segmented. The 
first and second maxillae have a general form similar to those of 
patersonii, but differ in the details of structure. In the first legs the 
endopod does not reach the distal end of the second exopod segment, 
and in the three following pairs of legs the spines on the outer margins 
of the exopods are stout, with small accessory spines on the inside at 
the base. In the fifth legs the endopods are a little more than a fourth 
as long as the exopods and are 1-segmented, with the terminal half 
divided into two unequal rami. The exopods are 2-segmented, the 
basal four and a half times as long as the terminal segment, the inner 
distal corner of each segment prolonged into a long slender spine. 
Total length 4.25 to 4.75 mm. Metasome 3 mm. long, 1.85 mm. wide. 
Male.—Metasome similar to that of the female except for the spines 
at the posterior corners. The spine on the left is short and curved, 
the one on the right is long and rodlike, curving around the process 
on the genital segment and almost reaching the second abdominal 
segment. The urosome, if the caudal rami are included, is half as 
long as the metasome and 5-segmented. The genital segment is wider 
than long, with a short triangular process on the left side and a much 
longer one on the right side. The four remaining segments are all 
the same width but vary in length, the second one the longest, the 
third one the shortest. The caudal rami are slender, enlarged distally, 
and as long as the last three abdominal segments combined. 
The antennae are longer than in the female and reach the genital 
segment; the swollen portion of the right antenna is shown on plate 
21, figure 289. The second antennae, mouth parts, and first four pairs 
of legs are like those of the female. The fifth legs are uniramose and 
3-segmented, the right leg being similar to that of patersonzi but the 
left leg having a very different end segment. Total length 3.95 to 
4.25 mm. 
Types.—[ Shortly after this long-delayed paper had reached galley 
proof, I was informed by Paul L. Illg, associate curator of the Na- 
tional Museum’s Division of Marine Invertebrates, that the Anomalo- 
cera that Dr. Wilson here described and named as new had been an- 
ticipated by William H. Sutcliffe, Jr., in the Journal of the Elisha 
Mitchell Scientific Society, vol. 65, No. 2, pp. 278-275, January 1950. 
We have therefore suppressed Dr. Wilson’s previously given name. 
Sutcliffe’s types, which were collected south-southwest of New River, 
N. C., in a surface tow, shallow water, 8 fathoms, are now on deposit 
in the National Museum, No. 89602, holotype female, and No. 89603, 
allotypic male. The specimens upon which the description by Wilson 
given above was based are from Albatross station 2396, surface, lati- 
tude 28°34’ N., longitude 86°48’ W., Gulf of Mexico, and carry 
U.S.N.M. No. 74111.—W.L.S. ]
