no. 2065. THE CRUSTACEA EUPHAUSIACEA— HANSEN. Ill 



B. Stations in the North Pacific. 



Sur. 163. November 11, 1891. Lat. 30° 31' 30" N.; long. 140° 05' 

 30" W. 330-300 fathoms. Tanner net. 2 specimens. 



Sur. 174. November 12, 1891. Lat. 29° 38' N.; long 142° 17' W. 

 330-300 fathoms. Tanner net. 1 specimen. 



Sur. 16. March 1, 1888. Lat. 4° 21' N.; long. 81° 59' W. Surface. 

 Surf. temp. 74°. 4.45 a. m. Moonlight. 14 specimens. 



Furthermore, the specimen from one of the stations enumerated in 

 1894 by Ortmann for S. suhmii G. O. Sars belongs to S. carinatum, viz. 



Sta. 3388. March 9, 1891. Lat. 7° 06' N.; long. 79° 48' W. 400-0 

 fathoms. 1 specimen (adult male). 



The two specimens from the Hawaiian Islands recorded by Ort- 

 mann in 1905 as S. carinatum have been correctly named and most of 

 the other specimens from the same station belong to the same species: 



Sta. 3801. Maich 19, 1902. Lat. 28° 31' N.; long 141° 47' W. 

 120-100 fathoms. 17 specimens. 



Finally the specimen recorded in 1905 by Ortmann as S. suhmii 

 belongs in reality to S. carinatum, and the determination is easy 

 because one of the prehensile legs is well preserved. 



Sta. 3803. March 21, 1902. Lat. 25° 39' 45" N.; long. 147° 41' 45" 

 W. 50 fathoms. 1 specimen. 



Distribution. — S. carinatum is very widely distributed in the Atlan- 

 tic, the Indian Ocean, and the Pacific. A detailed account is found 

 in my Harvard paper (1912), and a large number of places in the 

 Indian Ocean were recorded by Tattersall in 1912.

 4a-4d. 



Occurrence. — The animals from two of the stations enumerated by 

 Ortmann in 1894 for S. suhmii G. O* Sars belong to S. affine: 



Lat. 12° 34' N.; long. 97° 21' W. 8 specimens. 



Hyd. 2628. March 26, 1891. Lat. 0° 13' S.; long. 84° 52' W. 

 200-0 fathoms. 2 specimens. 



The two specimens from station 3414, referred by Ortmann to "S. 

 suhmi, ,} are so poor that they are unrecognizable. The specimen from 

 station Hyd. 2619 does not belong to that species but to the longicorne 

 group, being either S. affine or S. longicorne. 



Distribution. — S. affine is known from the Indian Archipelago and 

 the tropical east Pacific. 1 



44. STYLOCHEIRON ELONGATUM G. O. Sars (1883 

 1885. Stylocheiron elongatum G. O. Saes, Challenger Rep., vol. 13, p. 146, pi. 

 27, figs. 6-10. 



Occurrence. — Only a single specimen is at hand. 

 Sta. 2224. September 8, 1884. Lat. 36° 16' 30" N.; long. 68° 

 21' W. 1 specimen.
