curved, without secondary tooth. The setiferous lobe (fig. 2e, Is) 

 has, besides the six distal, strong and long setae, three thinner setae 

 on the distal part of the inner margin and five fine setae distributed 

 along nearly the whole outer margin; the oblique triangular lobe 

 constituting a kind of pouch is very large. 



Length. — One of the largest females (from lat. 39° 18' N.) is 22 mm. 

 long and a large male (from off Vancouver Island) is 21.5 mm. long. 



Remarks. — This species is distinguished from E. lucens H. J. Hansen 

 and E. frigida H. J. Hansen, especially by the shape of the processes 

 of the copulatory organs; furthermore, by the very short frontal 

 plate, the shape of the lobe of the first antennular joint, and other 

 minor points in the antennulae. 



Distribution. — To the interesting distribution shown by the fists 

 above it must be added that the Copenhagen Museum possesses speci- 

 mens from seven localities situated at Formosa, and especially near 

 Japan and Korea northward to lat. 39° N.; finally, that a number of 

 immature specimens were taken between San Francisco and the 

 Hawaiian Islands in lat. 33° 40' N. (Harvard paper).

Occurrence. — Taken only at a single place in the South Atlantic : 

 Sur. 12. January 15, 1888. Lat. 45° 22' S.; long. 64° 20' W. 

 Surface. 12.10 p. m. Surf. temp. 58°. 2 specimens. 



Distribution. — According to my paper quoted this species has been 

 taken four times in the southeast Atlantic and at a place between 

 New Zealand and Tasmania, while three of the places given by Sars 

 remain doubtful. In 1913 Tattersall 1 enumerated three additional 

 localities in the southeast Atlantic nearly west of the Cape of Good 

 Hope.
