ON SOME OIGOPSID CUTTLE PISHES.

also a member of the Ommastrepbidm, and the same may be 
said of Doratopsis, which Pfeffer has classified so closely with 
Tracheloteuthis (his Yerrilliola). 
Even Mastigoteuthis has affinity for one of the Chiroteu- 
thidae, for Verrill (6) mentions an olfactory lappet which I 
find is like the one I have described for Histioteuthis, though 
his mention of an auditory pore is puzzling. 
Taking all these points into consideration, I think we may 
safely dispense with the family name of Taonoteuthidae, and 
place the Chiroteuthidae as a subfamily under the Ommas- 
trephini.
