COPEPODS GATHERED BY ALBATROSS—WILSON 211 
tipped with an acicular spine as long as the last two segments com- 
bined. The penultimate segment also has a small spine at its outer 
distal corner. Total length 5.50 mm. 
Types.—U. S. N. M. No. 70727; station 4678 ; latitude 12°30’30” S., 
longitude 77°49’30’’ W., off Peru. 
Remarks.—This species may be recognized by the pointed fore- 
head, the 4-segmented urosome, the exceptional mandibular palp with 
its abnormal setae, and the peculiar characters of the exopod of the 
second antennae. The distance the pointed forehead projects beyond 
the base of the rostrum and the details of the fifth legs in the male 
are also aids in identification.
