Lat. 18° 16' S., long. 123° 34.4' W. Surface. 6 specimens. 



Lat. 19° 0.4' S., long. 125° 5.4' W. 300 fms. to surface. 2 specimens. 



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 tliird antennular joint is inedium sized, with its feebly 

 rounded distal angle about 100° and the front margin subvertical or distinctly 

 oblique. 



One of the largest specimens measm-es 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 allied E. 

 diomedeae, 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° 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. 

 8l5° E., from the South Cliinese 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.
