Sta. 4742. Feb. 15, 1905. Lat. 0° 3.4’ N., long. 117° 15.8’ W. 300 fms. to surface. 1 specimen. 
One of the largest specimens, a female, measures 17 mm., a very small 
adult male is scarcely 12 mm. long, but the most common size is 15-15.5 mm. 
Distribution.— This species has been established on a few specimens taken 
in the Indian Archipelago, at Lat. 0° 17.6’ S., long. 129° 14.5’ E. The Copen- 
hagen Museum possesses males from two localities, viz. Lat. 13° S., long. 103° 20/ 
E. (Capt. Andréa) and Lat. 34° 30’ S., long. 27° 40’ E. (Capt. Hartmann), the 
latter being in the most western part of the Indian Ocean, East of Port Elizabeth. 
The list above shows that the species has been taken ten times in a transverse 
belt about between the line and Lat. 19° S. in the area explored by Agassiz 
1904-1905, while it was not met with in the larger northern and smaller southern 
part. Furthermore the list seems to show that the species at least as a rule does 
not live at the surface, but the specimens in the Copenhagen Museum have 
certainly been taken near the surface and probably during night.

I have nothing to add to the description in the ‘‘Siboga”’ paper. 
Distribution.— Only the two specimens recorded from the Pacific are known 
hitherto; Ortmann’s specimens from the Hawaiian Islands referred (1905) to 
E. pseudogibba belong to E. hemigibba H. J. H. The Copenhagen Museum and 
the Monaco collection contain numerous specimens from several localities from 
the eastern warmer temperate and tropical Atlantic North of the line; further- 
more I have seen specimens from the Bay of Bengal (‘‘Galathea”’ Exp.) and 
from Lat. 11° 16’ S., long. 103° 50’ E. (Capt. Andréa).— The specimens from 
twelve localities in all in the Copenhagen Museum are nearly all males and 
have certainly been taken at the surface during the night. 
(The fourth species of the gibba-group sens. strict., E. hemigibba H. J. H. 
(see the “Siboga” paper) is very common in the Atlantic from Lat. 42° N. to 
southwest of the Cape of Good Hope, and in the Indian Ocean from Port Eliza-
