while Ortmann gave it to be 36-40.5). Finally, the fin is specially 

 thickened at the posterior end, a fact not mentioned by Ortmann but 

 which constitutes an important diagnostic character, in as much as it 

 serves to distinguish at once the species from any other of the genus.

 Two ££. specimens obtained by K. Mitsukuri at Enoura, Suruga 

 Prov., April 1884 (Sci. Coll.). Mantle-length 87 mm., 77 mm. The 

 characters agree well with Hoyle's description of the Challenger 

 specimen ; only the posterior end of the fin does not reach the ventral 

 surface of mantle, as it did in the Challenger specimen, but extends 

 straight on toward the posterior mantle-end as usual in this genus. 



This is a very variable species, as is shown by the fact that the 

 descriptions of it given by Hoyle, Ortmann, Appellöf and Wülker 

 disagree with one another in some points. The specimens which I 

 examined always showed some discrepancy from the descriptions
