the caudal peduncle, may safely be estimated as over eight inches. 

 They are thus rather large examples. 



Dr. Giinther has called attention to the existence of two varieties 

 of the species, of which the typical Norwegian forms were found to 

 differ from the Scottish chiefly in the greater attenuation of the body 

 and the greater size of the eye. The same difference was found to 

 exist between the solitary specimen from below the 100 fathoms line 

 and the smaller ones from lesser depths among the Irish survey 

 collections. Without entering into details, it may suffice for the 

 moment to remark that Mr. Dunn's specimens agree with the larger 

 Norwegian and deep-sea Irish type, and not with the smaller Scottish 

 and Irish variety. ^ -^Y j jj
