Family LAMPADIOTEUTHID^ new family. 



Squids of small size, with terminal, sagittate fins. Arms with 

 two rows of suckers. Tentacle clubs with four rows of suckers. 

 No hooks present on either arms or tentacles. Buccal membrane 

 eight-pointed. Gladius with lateral wings, but no terminal cone. 

 Luminous organs present in the pallial chamber, on the eyeball, 

 along the stalk of the tentacles, and at the base of the tentacles. 



For the present the characters of the new family must be drawn 

 from those of the type genus alone, so no doubt important emenda- 

 tion must later take place. 



I would tentatively place the Lampadioteuthidce between the 

 Lycoteuthidce on the one hand and the Enoploteuthidce on the other. 

 The group cannot be referred to the Lycoteuthidce on account of the 

 entirely different construction of the gladii. Some teuthologists 

 may prefer to place it with the Enoploteuthidce, but it seems to me 

 that the complete lack of hooks or modified suckers on either tenta- 

 cles or arms produces an anomaly fatal to this arrangement. Of 

 course a fuller knowledge of the anatomy of all these forms than is 

 now possible is as likely as not to bring about an entirely different 

 classification, but I think the one adopted is for the meanwhile the 

 most reasonable.
