Type. — Catalogue no. 214314, United States National Museum [S. S. B. 260]. 
Type locality. — Albatross station 3989, 385 to 733 fathoms, bottom of coral sand and rock, vicinity of 
Kauai Island, June ii, 1902; a single specimen. 
Material examined. — The type is unfortunately unique. 
Remarks. — Although the whole aspect of this species is suggestive of Chiroteuthis rather than Masti- 
goteuthis, the short olfactory papilla and the apparent absence of photophores on either the eyes or the 
ventral arms preclude its reference to that genus as I had originally placed it. On the other hand, it 
seems to have little in common with the remarkable M. agassizii Verrill, which is the type species of the 
latter genus. Verrill’s species is notable for the extremely rich development of photogenic organs over 
the entire outer integument, and possesses other features which induce me to believe that it will 
eventually prove generically distinct from almost all the more recently described species usually 
associated with it. Even from the latter forms the present species is strikingly diSerent, and as the 
condition of the single specimen is confessedly not all that might be desired, besides being very likely 
immature, it may be that better material may after all accomplish its restoration to Chiroteuthis. 
In purely superficial characters M. famelica seems nearer to C. pellucida Goodrich of the Bay of 
Bengal than to any other form of either genus known to me, but differs in the much larger fins, shorter 
neck, more poorly developed arms, and a number of other characters. Both species are remarkable for 
their gaunt slender body, and to this feature is due the specific name of the Hawaiian form.

Mantle border firmly fused with the head in the nuchal region and with the base of the funnel on 
either side. Body usually membranous and transparent; nearly colorless. Eyes usually large, often 
pedtmculate. Sessile arms with two rows of suckers only; tentacles with four rows of suckers, which 
frequently extend down the stalk for the greater portion of its length; hooks may occur on the tentacle 
club, but only in one or two genera. Photogenic organs may be numerously developed on the ventral 
aspect of the eyeball, may occur within the pallial chamber, or may be entirely absent.

Mantle thin, saccular; often much inflated. Fins of rounded outline, terminal, small to moderate 
in size. Two diverging series of small conical cartilaginous tubercles extend back from the ventral 
point of fusion of the mantle and funnel on either side; in some forms a similar series may be present
