Family CIEEOTEUTHIDAE. 



Cirroteuthidae, Keferstein, '66, p. 1447. 



This family was defined by its founder Keferstein ('66, p. 1447) as follows : 

 " Kbrper mit rundlichen Flossen, von weicher Consistenz. Mantel rundum 

 bis zur Trichterbasis mit dera Kopfe verwachsen. Eine knorpelige, breite 

 innere Schule (wahrscheinlich als verwachsene Riickenknorpel anzuseben)." 

 This definition still holds good in all essential points : there might be added to 

 it the words, — " suckers in a single series alternating with paired cirri, raduli 

 absent ; " and in view of the variety which has since been shown to exist in 

 the form of the internal cartilage, the word " breite " might be advantageously 

 omitted. 



Here are included at present the following genera : — 



Cirroteuthis. — Dorsal cartilage saddle-shaped ; umbrella present, intermedi- 

 ate web present or absent. 



Stauroteuthis. — Dorsal cartilage horseshoe-shaped with the free ends 

 directed towards the head ; umbrella present, intermediate web present. 



Froekcnia. — Dorsal cartilage horseshoe-shaped, the free ends directed 

 towards the head ; umbrella absent. 



CIRROTEUTHIS. 

 Cirroteuthis Eschriclit, '36, p. G27. 



The species of this genus hitherto known may be discriminated by the 

 annexed key : — 



I Total length to brcadtli about 3:1 plena Verrill. 



' I Total length to breadtli more than 4:1.... 2. 

 Length and breadth of fin equal to length and 



breadth of body meqaptera Vorrill. 



Length and breadth of fin less than length and 



breadth of body 3.
