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 medimii sized, with its feebly 

 rounded distal angle about 100° antl the front margin sub vertical or distinctlj'' 

 obhque. 



One of the largest specimens measures 13 mm. in length; most of the adults 

 are about 10-12 mm., sometimes even only S-9 mm. 



Distribution. — This species is more widely distributed than the aUied E. 

 diomcdeap, but the number of specimens seen by me of E. mutica is yet much 

 smaller than the number of the other species. In the tropical East Pacific 

 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° 1-4' S., while in the major portion of this southern 

 part E. diomedcae 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 cui'rent, finally Lat. 38° S., long. 12° E. Furthermore the Copenhagen 

 Museum possesses specimens from the Indian Ocean about at Lat. 23° S., long. 

 8l|° 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 

 freciuently been taken at the surface.
