ture 44.1, 2 specimens. Bathymetrical range, 244 to 1,008 fathoms. 

 Temperature range, 44.1 to 31.8. Six specimens. 



The most careful comparison of these specimens with a large series 

 from the West Indies, among which is the type of adspersus, has failed 

 to bring to light any character by which they can be distinguished. 

 I have also examined carefully three cotypes of annectens and I do 

 not find that the characters, by which the distinguished Danish 

 zoologists suggested that that species might be recognized, are in any 

 degree reliable. I have therefore placed the name as a synonym of 

 adspersus, a conclusion which Ltitken and Mortensen themselves pre- 

 dicted might prove to be correct. We have in adspersus then, an 

 intertropical, if not a cosmopolitan species, for it has been taken in the 

 West Indian region by the Blake, in the eastern Atlantic by the
