usual at this stage and the arms are shorter than customary. The suckers of the tentacular 

 arms are arranged in a formation more closely serried than those figured by Pfeffer 

 and Chun. 



Family 3. Enoploteuthidse. 



Abralia (Compsoteuthis), sp. 



One example, sex indeterminate, from off Providence, between surface and 10 fm^ 

 (1536). 



The specimen is in a very poor condition, the head and arms being damaged, but 

 from the characters that are apparent it is probably referable to this genus. 



Another very badly damaged specimen from 250 fathoms off' Desroches Atoll (1532) 

 is possibly referable to Abralia also. 



Family 6. Benthoteuthidse. 



Cliunoteuthis minima, n. gen. n. sp. (Plate 65, fig. 2). 



One example, sex indeterminate, from between Alphonse and Providence Islands, 

 900 fathoms (1528). 



This specimen has been the source of a considerable amount of trouble. In the first 

 place, it arrived in a very shrivelled-up condition, apparently having sufiered desiccation 

 at some time, and in consequence a good many of its external features have been 

 obliterated. In the second, it does not readily fall into line with any described and figured 

 OEgopsid genus. Even its family relationships are very doubtful. The result is that, 

 although it certainly calls for description, its exact position is extremely problematical, 

 seeing that examination of the anatomy and mantle cavity is denied by the state of its 

 preservation. After much hesitation it has been decided to assign it to the BenthoteuthidsB 

 on the strength of its general superficial appearance. 



Chunoteuthis, n. gen. 



General appearance. Yery small in size* (length of mantle from apex to base of 

 arms, 3 mm., length of tentacular arms, 5"5 mm. (? + l mm.), width 1 mm.). The head is 

 large and oblong in shape with very large, prominent eyes upon which no traces of 

 accessory light organs are to be seen. The body is saccular but laterally compressedf with 

 a well-marked dorsal carina and a very prominent nuchal protuberance on the dorsal 

 mantle edge. Posteriorly two small subquadrate fins are found. 



The tentacular arms are very long and slender. The club is not very much expanded 

 and the suckers upon it are irregularly disposed. The sessile arms were so tightly 

 entangled that they could not be separated without damage. They are relatively long 

 and apparently subequal in size, and all exhibit prominent suckers. 



The colouring has of course disappeared, but traces of dark chromatophores appear 

 upon the arms. 



C. minima, n. sp., with the characters of the genus. 



Type in the Zoological Department of the British Museum. 



* The adult condition is testified by the length of the arms both sessile and tentacular. 

 t It is not impossible that the lateral compression may be an artefact character.
