Fammy CIRROTEUTHIDAE. 
Cirroteuthidae, Keferstein, '66, p. 1447. 
This family was defined by its founder Keferstein ('66, p. 1447) as follows 
A CM. mit rundlichen Flossen, von weicher Consistenz. Mantel rundum 
bis zur Trichterbasis mit dem K opfe verwachsen. Fine knorpelige, breite 
innere Schale (wahrscheinlich als verwachsene Rückenknorpel anzusehen)." 
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, radula 
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. 
Stawroteuthis. — Dorsal cartilage horseshoe-shaped with the free ends 
directed towards the head; umbrella present, intermediate web present, 
Froekenia, — Dorsal cartilage horseshoe-sl haped, the free ends directed 
towards the head ; umbrella absent.
