These specimens, though the mantle-length is only some 5 mm., 'show dis 

 tinctly the characteristic form of the articulation with the base of the siphon. 



SYMPLECTOTEUTHIS. 



Si/mplectoteuthis Pfeffer, : 00, pp. 178, 180. 



This genus has recently been created by Dr. Pfeffer for the reception of the 

 species named below, on account of the fusion of the mantle with the base of 

 the funnel on either side.

 Symplectoteuthis oualaniensis Pfelfer, : 00, p. 180. 



Habitat. — Station 3363, east of Cocos Island (surface tow-net) : February 

 26, 1891 ; lat. b° 43' N., long. 85' 50' W., 978 

 fathoms ; white globigerina ooze ; temperature, sur- 

 fiice 83°, bottom 37. °5 ; one specimen. [H. 53.] 



The funnel groove (see Figure F) somewhat re- 

 sembles that figured b}' Steenstrup ('80, p. 81) for 

 Todarodes sagittatus and Ommastrephes pacificus ("80, 

 |. ^ p. 79, Figs. 4, 5) except that the area occupied by 



k^ the cutaneous folds is very much narrower. In this 



''•-^ ' """-^H iL'spcct it differs from the original drawing by Les- 



son ("29, Plate 1, Fig. 2) of his L. oualaniensis, 

 where the funnel groove is shown as though it were 

 striated all over.

Profcs.sor Chun's re-tliscovery of the curious immature form described by 

 Souleyet ('52, p. 17, Piute 1, P'igs. 15-21) is of extreme interest, and although
