CEPHAI^OPODA OP THE HAWAIIAN ISLANDS. 
275 
Type. — Lcetmoteuthis lugubris Berry 1913, a species of the Hawaiian Islands. 
The genus is closely allied to both Cirroteuthis and Stauroteuthis , but differs in the absence of paired 
cirri and the presence of an odontophore.

Lcetmoteuthis lugubris Berry 1913, p. 563. 
Body large, rounded posteriorly. Lateral fins situated well back on the mantle, but small, 
transversely elongate, their greatest dimension (width) about twice as great as their length (fig. 2). 
Funnel thin walled, very large and 
broad; interior ample. Eyes prob- 
ably large. 
Arms long, appearing merely as 
thickenings or soft folds in the 
broad and ample umbrella and witli- 
out any intermediate web connecting 
them thereto. Umbrella longest be- 
tween the ventral arms, but every- 
where extensive though very thin. 
Suckers large, flattened, distant; in 
a single series, though frequently 
somewhat zigzag; slightly, but not 
much, firmer in texture than the 
arms or umbrella; round-tubercular 
in shape; the apertures contracted, 
their margins crenulate. Paired cirri 
indistinguishable . 
Mandibles large, compressed; 
but, with the exception of the sharp 
powerful beaks, thin and compara- 
tively fragile; color black, homy at 
margin. (PI. xuix, fig. 1, 2.) 
A very large and perfectly de- 
veloped radula present; of the seven 
rows of teeth the tricuspid medians 
are considerably the largest. 
Surface color a livid dark brown- 
ish slate, with a somewhat bluish 
cast over the inner surface of the 
umbrella in preserved specimens. 
The label accompanying tlie type contains a note to the effect that the color of the specimen when 
captured was chocolate brown. Chromatophores small, numerous, and heavily distributed over the 
entire surface.
