Remarks. — One of the surprises offered by the "Endeavour" 

 material was the occurence of no less than four adult speci- 

 mens of both sexes of this rare and little known genus of 

 Squids. Furthermore, although the species to which they 

 belong is admittedly close to the Japanese E. chunii, IshikaAva 

 (1914, p. 401), as well as to the type of the genus, the poorly 

 understood Atlantic E. leptura (Leach) (cf. d'Orbigny, in 

 d'Orbigny and Eerussac, 1839, p. 337, Onvchoteuthes, pi. 6, 

 pi. 11, figs. 6-14, pi. 12, figs. 10-24), it still seems clearly 

 distinct enough to be awarded a separate name. Its most 

 conspicuous peculiarity lies in the arrangement of the photo- 

 genic organs of the ventral aspect of the body. These, although 

 much more numerous and crowded than would seem to be 

 the case in either of the older species, fail to show the aggre- 

 gation into more or less definite longitudinal bands character- 

 istic of both the latter. The specimens further differ from 

 E. chunii in the more reduced sucker-bearing area on the 

 sessile arms, the greatly diminished number of suckers on the 

 terminal portion of the tentacle club, and the consequently 

 smaller area of the organ occupied by them, the lack of small 

 suckers between the carpal apparatus and the hooks on the 

 main portion of the club, certain details in the number of 

 hooks and relative position of the protective membranes on 

 the hectocotylized arm, and so on. None of these peculiarities 

 are very striking, but are relatively constant in the material
