Twenty-two specimens belonging to this distinct species, were obtained from the plankton 
collected at the following stations. 
Stat. 16, 2 specimens. — Stat. 35, 3 specimens. — Stat. 71,1 specimen. — Stat. 109, 3 spe- 
cimens. — Stat. 110,.2 specimens. — Stat. 124, 3 specimens. — Stat. 144, I specimen. — 
Stats. 194—7, 2 specimens. — Stat. 204, 3 specimens. — Stat. 210°, 2 specimens. 
The female of this Poxtellopszs can readily be recognised by the structure of the fifth 
pair of feet, and by the right furcal joint being about double the size of the left furcal joint. 
Pontellopsis kramert is apparently a rare species. It has hitherto only been known 
from the Indian Ocean and from the Red Sea. 
3. Pontellopsis perspicax (Dana).

Pontellina perspicax Dana, 1852, p. 1155, pl. 81, 
Pontellina pulchra Dana, 1852, p. 1157, pl. 81. 
Monops perspicax Giesbrecht, 1893, p. 486, pls. 26 & 41. 
Pontellopsis perspicax Giesbrecht & Schmeil, 1898, p. 147. 
Pontellopsis perspicax Thompson & Scott, 1903, p. 253. 
Four females and one male identical with the above species were found in the plankton 
collected at Station 35. 
This species has a certain amount of resemblance to Pontellopsis armata, but the two 
sexes can readily be separated by the structure of the fifth pair of feet. 
Pontellopsis perspicax has only yet been recorded from the Atlantic and Indian Oceans.

Thirteen specimens of this form were obtained from the plankton collected at the foll- 
owing stations.
