Distribution. — In the Harvard paper a long list of localities situated 

 in the east Pacific between lat. 22|° N. and lat. 12^° S. has been 

 published. 



25. EUPHAUSIA LAMELLIGERA H. J. Hansen (1911). 



1912. Euphausia lamelligera H. J. Hansen, Mem. Mus. Comp. Zool., vol. 35, 

 No. 4, p. 250, pi. 8, figs. 4a-4e; pi. 9, fig. la. 



Occurrence. — Among the unnamed material specimens are at hand 

 from only a single station in the tropical east Pacific: 



Sur. 16. March 1, 1888. Lat. 4° 21' S.; long. 81° 50' W. Sur- 

 face. 4.31 a. m. Moonlight. Surf. temp. 74°. 4 specimens. 



Besides, some of the specimens referred by Ortmann in 1894 to 

 E. mucronata G. O. Sars belong to E. lamelligera: 



Hyd. 2619. March 11, 1891. Lat. 7° 31' N.; long. 78° 42' 30" W. 

 300-0 fathoms. 6 specimens. 1,000-0 fathoms. 12 specimens. 



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

 400-0 fathoms. 19 specimens. 



March 7, 1891, thus near lat. 6° 21' N.; long. 80° 41' W. Surface. 

 1 specimen. 



Distribution. — This species is, as shown in the paper quoted, rather 

 common in the tropical east Pacific between lat. 19° 52' N. and lat. 

 10° 17' S. 



26. EUPHAUSIA GIBBOIDES Ortmann (1893). 



1912. Euphausia gibboides H. J. Hansen, Mem. Mus. Comp. Zool., vol. 35, No. 4, 

 p. 252, pi. 9, figs. 2a-26. 



Occurrence. — The unnamed material contains specimens from a 

 station in the northwest Atlantic and from a place in the tropical 

 east Pacific off Chile: 



Sta. 2098. October 1, 1883. Northwest Atlantic. Lat. 37° 40' 

 30" N.; long. 70° 37' 30" W. 1 specimen. 



Sta. 2808. April 4, 1888. East Pacific. Lat. 0° 36' 30" N. ; long. 

 89° 19' W. 1 specimen (male). 



Furthermore, Ortmann in 1894 correctly referred specimens from 

 three stations in the Pacific to this species: 



Sur. 540. January 14, 1891. Lat. 35° 19' 30" N.; long. 125° 21' 

 30" W. 300-0 fathoms. 3 specimens. 



Hyd. 2627. March 25, 1891. Lat. 0° 36' N.; long. 82° 45' W. 

 1,832-0 fathoms. 1 specimen (male). 



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

 200-0 fathoms. 1 specimen. 



Finally I found a somewhat young specimen of this species among 

 the specimens referred by Ortmann to E. mucronata G. O. Sars from 

 the following locality: 



Sta. 3414. April 8, 1891. Lat. 10° 14' N.; long. 96° 28' W. 

 300-0 fathoms. 1 specimen.
