Tentacles slender, half as long again as the arms; tentacular club 

 armed with four rows of suckers arranged as follows: (7) two dorsal 

 rows of small suckers, largest at the middle of the club, but extending 

 for its entire length; (2) two ventral rows of similar suckers on the 

 distal portion of the club, replaced proximally by (3) a single row of 

 five or six rather large hooks; (4) at the base of the 

 club, upon the carpus, a fiixing apparatus consisting of 

 four or five extremely minute suckers and a few pads. 

 Buccal membrane seven-pointed, coarsely papillose 

 within; color uniformly pale, with a few slightly darker 

 spots (chromatophores) scattered over the outer sur- 

 face. 



Photophores numerous, quite symmetrically distrib- 

 uted in about ten ill defined longitudinal rows on the 

 ventral surface of the mantle; upon the ventral surface 

 of the head five rows, one of them median; upon the 

 funnel four rows, each comprising a single large organ 

 and several smaller ones; upon each of the ventral 

 arms three rows, two of them upon the body of the 

 arm, the third extending along the marginal keel for 

 over half its length; upon the ventral 

 periphery of the right eyeball a very 

 prominent row of five large, reddish, 

 bead-like organs conspicuously dif- 

 ferent from the others. (The left eye 

 was so retracted as to render exam- 

 ination impossible without mutilation 

 of the specimen.) 



Color of preserved specimen a dirty bufi^, the 

 gladius showing through the dorsal integument as 

 a very prominent median dark line; photophores 

 bluish, with whitish centers; chromatophores nu- 

 merous, especially on the dorsal aspect, but largely 

 replaced ventrally by the photophores. 



Length, excluding tentacles 56.5 mm.; length of 

 mantle 34 mm. ; maximum width of mantle 10 mm. ; 

 width across fins 22 mm. 



The type, which was the only specimen obtained, 



was dredged in about 192 fathoms, coarse coral sand 



and shell bottom— station 4122, oft' the southwest 



coast of the island of Oahu. 



This species agrees with Pfeffer's "^o^Z^i-group," of the genus 



Abralia, as defined by that author," in that "die Leuchtorgane
