Finally from the following Station: — 
Hyd. Sta. 3998 (236). Jan. 28, 1900. Lat. 6° 34’ N., long. 170° 59 E. Surface. Electric light. 6 
specimens. “Albatross.” ; 
Remarks.— To the description in the ‘‘Siboga” paper may be added, that , 
the dorsal keel on the third antennular joint is medium sized, with its feebly 
rounded distal angle about 100° and the front margin subvertical or distinctly 
oblique. 
One of the largest specimens measures 13 mm. in length; most of the adults 
are about 10-12 mm., sometimes even only 8-9 mm. 
Distribution This species is more widely distributed than the allied #. 
diomedeae, but the number of specimens seen by me of H. mutica is yet much 
smaller than the number of the other species. In the tropical East Pacifie 
the two species were seldom taken together or at localities near each other, 
E. mutica being restricted to the southern part of the area explored, not being 
found North of Lat. 10° 14’ S., while in the major portion of this southern 
part E. diomedeae was entirely wanting.— E. mutica has been taken by the 
Prince of Monaco in the Sargasso Sea at Sta. 137 and Sta. 142 (West of Long. 
40° W., South of Lat. 42° N.) and the Copenhagen Museum possesses speci- 
mens from the following places in the Atlantic: — Lat. 39° 30’ N., long. 50° 
W.; Lat. 33° N., long. 47° W.; Lat. 24° N., long. 22° W.; the West Indies; 
the Guinea current, finally Lat. 38° S., long. 12° E. Furthermore the Copenhagen 
Museum possesses specimens from the Indian Ocean about at Lat. 23° S., long. 
813° E., from the South Chinese Sea: Lat. 19° 14’ N., long. 116° 6’ E., and from 
Japan: Lat. 31° 20’ N., long. 132° 29’ E. The “‘Siboga”’ captured some speci- 
mens at two Stations in the Indian Archipelago.— The species has very 
frequently been taken at the surface.
