The latter only lias an apical set of suckers to the tentacular club. 

 This genus is greatly in want of revision by some naturalist who cotild have access to 

 the type-specimens.

Subfamily Cheiroteuthid^. 



Cheiroteuthis macrosoma, n. sp. (PI. 3. figs. 51, 52, 53, 54, 55, 50, & 57.) 



A single female specimen of this elegant Cephalopod was captured off the Kistna 



delta, lat. 12° 50' N., long. 81° 30' E., at a depth of 475 fathoms. 



From figure 51 and the measurements given below, it will be seen that this new 



species of Clieiroteutlds is remarkable for the great length and graceful tapering of the 



mantle.

The colour of this specimen in spirit is of a dull purplish-brown, lighter and yellower 

 on the lower surface, darker and inclining to heliotroije and blue on the uppper surface 

 of the mantle, head, and on the outer surface of the arms. The buccal membrane, inner 

 surface of the arms and suckers are paler. 



The mantle, as seen in the figure from the ventral surface, tapers gradually until the 

 middle of the fin, whei-e it is very narrow ; it then enlarges slightly, and is produced 

 beyond the fin at its apex {ap.2)rol.) very much as in Cheiroteuthis Ficteti, a species
