One of the large.st 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° 17.0' S., long. 129° 14.5' E. The Copen- 

 hagen Aluseum possesses males from two localities, ^■iz. Lat. 13° S., long. 103° 20' 

 E. (Capt. Andrea) and Lat. 34° 30' S., long. 27° 40' E. (('apt. Hartmaim), the 

 latter being in the most western part of the Indian Ocean, East of Port Ehzabeth. 

 The list above shows that the species has been taken ten times in a trans\-er,se 

 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 

 jxart . Furthermore the Hst seems to show that the species at least as a rule does 

 not live at the sm'face, but the specimens in the Copenhagen IMuseum have 

 certainly been taken near the surface and proljably din-ing night.

I have nothing to add to the description in tlie "Siboga" paper. 



Distribjition. — Only the two specimens recorded from the Pacific are known 

 hitherto; Ortmann's specimens from the Hawaiian Islands referi-ed (1905) to 

 E. pseudogibba belong to E. hcmigibba 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 ("Clalathea" Exp.) and 

 from Lat. 11° 16' 8., long. 103° 50' E. (Capt. Andrea). — The specimens from 

 twelve localities in all in tlie ( 'openhagen Museum are nearly all males and 

 have certainly been taken at tlie surface during the night. 



(The fovuili species of the f//66a-group sens, strict., E. Iiemigiltba H. J. H. 

 (see the "Siboga" paper) is very common in the Atlantic from Lat. 42° N. to 

 southwest of the Cajie of Good Hope, and in tlie Indian Ocean from Port Eliza-
