The suckers are crowded on all the arms except in large specimens 

 and are in a single series. They are deeply embedded in the gelat- 

 inous coating. According to Thore, they have an average mdex of 

 5.9 but those of the female have an index of 4.3. The web is well 

 developed and is especially prominent between the dorsal and the 

 ventral arms. In the smaller of the two, sector E was deepest, with 

 an mdex of 38.4. 



The funnel is large and extends past the eyes. The funnel organ 

 is distally placed and distinct. It is inverted V-shaped, with fat 

 oval lateral members, and narrowly united at the apex. 



Measurements and indices of a female Japetella diaphana Hojde, 

 1885, are: 



Type. — British Museum (Natural History). 



Type Locality.— North of Papua, 147° E., 42' S., 1100 fms., 

 Globigerina ooze. 



Discussion. — This species has been revised by Thore (1949) and 

 nothing can be added here. Accordmg to this author the young live 

 at about 200 m., just below the discontinuity layer. Later, they 

 migrate downward, adults of more than 40 mm. living below 333 m. 

 and concentrated at two levels, one at 1750 m. and the other at 

 2500 m. 



Distribution, — Cosmopolitan in deep water in the tropical and 

 warm temperate seas. It has been previously reported from the 

 Philippines {see Thore, 1949).

No specimens of this bathypelagic octopod were taken by the 

 Albatross. It is Usted here on the authority of Thore (1949) who 

 recorded it from several localities in the Philippine Islands. Details 

 of external morphology, anatomy, and distribution are available in 

 Thore. 



Type. — U.S. National Museum. 



Type Locality.— 37°12'20'' N., 69°39' W., in 2949 fathoms 

 (VerriU).
