 Pontellopsis kramen Wolfenden, 1905 (a), p. 102 1, pi. XCVIII. 



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, r specimen. — 

 Stats. 194 — 7, 2 specimens. — Stat. 204, 3 specimens. — Stat. 210', 2 specimens. 



The female of this Pontellopsis can readily be recognised by the structure of the fifth 

 pair of feet, and by the right furcal joint being about doublé the size of the left furcal joint. 



Pontellopsis krameri 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 pulchra Dana, 1S52, p. 1157, P^ 81. 



Monops perspicax Giesbrecht, 1893, p. 486, pis. 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 artnala, but the two 

 sexes can readily be separated by the structure of the fifth pair of feet. 



Pontellopsis perspicax has only vet been recorded from the Atlantic and Indian Oceans.

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



owing stations.
