SCHTZOPOPA, STOMATOPOPA. AND NON-ANTAHCTTC ISOl'OPA. 187 



Discovery. 



Lat. 30 43' S., long. 21 36' W. Six. 

 Lat. 35 10' S., long. 13 40' W. Three. 

 Lat, 30 27 -V S., long. 8 2u' W. One. 



At present, this species is known only from the tropical Atlantic (HANSEN), Indian 

 Ocean, and Mediterranean (TATTKRSALL). 



Euphausia pseudogibba, < >rtmann. 



E. pseudogibba, Ortmaun, 1893. 

 E. pseudogibba, Hansen, 1910. 

 E. pseudogibba, Hansen, 1912. 



Scotia. 



Station 29, lat. 12 31' N., long. 25 9' W., tow-net. One. 



This species is known from the tropical Atlantic, Indian Ocean, and the Pacific, 

 from which the types were recorded. It is most generally distributed in the Indian 

 Ocean and the Atlantic, and decidedly rarer in the Pacific. 



Euphausia gibboides, Ortmaun. 



E. gibboides, Ortmann, 1893. 

 E. gibboides, Hansen, 1911. 

 E. gibboides, Hausen, 1912. 

 Discovery. 



Lat. 36 27^' S., long. 8 20' W. One female, 22 mm. 



This specimen differs from the description and figures given by HANSEN (1912) 

 in the form of the lobe on the first joint of the antennular peduncle. This lobe has a 

 bifid extremity, the outer process quite minute, and much smaller than the inner and 

 main extremity. The specimen, however, agrees otherwise so well with E. gibboides 

 that it has seemed best to include it in that species for the present, at any rate until 

 male specimens are forthcoming and the copulatory organs on their pleopods can be 

 investigated. 



Euphausia longirostris, Hansen. 



E. lonyiroftris, Hansen, 19086. 

 E. longirostris, Hansen, 1911. 

 Discovery. 



Lat. 37 47' S., long. 3 59' E. One adult male, 19 mm. 



When first I examined this specimen, I determined it as a variety of E. spinifera, 

 G. 0. Sars, with which it agrees very closely, except in regard to the lobe from the
