680 ON CEPHALOPODA FROM THE MONTE BELLO ISLANDS. 
Internal characters.—The mandibles (text-fig. 1, D). 
The radula (text-fig. 1, E) resembles that of S. kochii figured 
by Appellof (3) pretty closely ; but differs in the condition of the 
basal plate of the median tooth, which is much deeper and of a 
different shape, in certain characters of the lateral tooth and of 
the inferior marginal. It is unfortunately impossible to give a 
fuller account of the internal characters, owing to the fact that 
only one specimen is available for examination. 
Locality. Dredged off Hermite I. (Monte Bello Islands), 
W. Australia. 
Type in the British Museum (Zoological Department). 
2. POLYPUS sp. 
Two specimens from the same station (one immature). 
This form, which might be referable to more than one Pacific 
species, cannot be satisfactorily identified.
