Stat. 98, 2 specimens. — Stat. 117%, I specimen. — Stat. 124, 2 specimens. — Stat. 144,

This is the largest known member of the genus. The two sexes can easily be identified 
by the structure of the fifth pair of feet. 
Pontellopsis regalis has a moderately wide distribution. It has been recorded from the 
Atlantic, Indian and Pacific Oceans, and from the Mediterranean. 
5. Pontellopsts strenua (Dana).

specimens were found in the plankton obtained from the following two stations. 
Stat. 96 (night), 4 specimens. — Stat. 117°, 6 specimens. 
This species is closely related to Pontellopsis regalis, but it can easily be distinguished 
by its smaller size, and by the structure of the fifth pair of feet of the two sexes. 
Pontellopsts strenua appears to be rather limited in its distribution. It has only been 
recorded from the Indian and Pacific Oceans. 
The 
figures of Pontella strenua given by Professor Brapy in the report on the ‘Challenger’ 
Copepoda evidently represent two forms, but neither of them are identical with Dana’s Pontella 
strenua. Fig. 17, Plate XLV, seems to be identical with the male fifth pair of Poxtella atlantica 
(M. Edwards). Fig. 18, Plate XLV, appears to be the abdomen of the male of Pontellopsis regales. 
6. Pontellopsis villosa Brady.

Pontellopsis villosa Sars, 1905(6), p. 6. 
One female identical with the above species was found in the plankton collected at 
Station 138. 
The 
female of this Pontellopszs is somewhat similar to Poxtellopsis armata. The abdomen, 
however, is composed of a single joint. The abdomen of the female of Pontellopsis armata 
is two-jointed. 
Pontellopsts villosa has been recorded from the Atlantic and Pacific Oceans, and from 
the Mediterranean.
