Thisis clearly an emendation of Alecto, as the genus is referred 
to Leach.

The fact that this species was only dredged twice by the 
Challenger at stations 78° apart, the single specimen from Station 
No. 160 showing certain differences from those from Station No. 
244, makes it necessary, if possible, to fix upon a definite type- 
locality, in case the differences should prove to be constant. Now, 
where the characters are first given (in the key on p. 158) the 
only differential character mentioned is the number of cirrus seg- 
ments. The single specimen from Station No. 160 had no cirri, 
and therefore could not have been the original from which this 
character was taken. The type-locality must, then, of necessity, 
be the other station.
