REPORT OF COMMISSIONER OF FISH AND FISHERIES. [70] 
Lestoteuthis (gen. nov.).—Tentacular club with numerous suckers, and 
few large central hooks. Sessile arms dissimilar; lower ones with four 
rows of suckers; upper, with two central rows of hooks, alternating with 
marginal suckers on each side. Pen narrow, with a short, hollow, term¬ 
inal cone. (Type, L. Kamtscliatica Middendorff, sp.) 
Sessile arms with hoohs only. v 
Verania. —Tentacular club with hooks; sessile arms with hooks in two 
rows. Fins large and broad. Pen lanceolate. 
Acanthoteuthis. —Tentacular and sessile arms with hooks. (Fossil.) 
Ancistrochirus. —Tentacular and sessile arms with hooks in two rows. 
Pen lanceolate. Fins extending forward to edge of mantle. 
Enoploteutliis (typical).—Tentacular club with two rows of hooks, and 
with a cluster of small connective suckers and tubercles on the wrist. 
Sessile arms all with hooks, in two rows, extending to the tips. Fins 
short. Pen lanceolate. 
The position of Moroteuthis among the genera enumerated above must 
remain uncertain, for the present, because the armature of the tentacular 
club is unknown. But as it has smooth-ringed suckers ou the ventral 
arms, at least at-the base, it is probable that the genus is more nearly 
allied to the genera in the first group. But it differs very decidedly 
from all those named, in the form of the pen, and in having a long, solid 
cartilaginous cone, shaped like a large Belemnites , appended to its pos¬ 
terior end. In respect to this feature of the pen, this genus differs from 
all existing genera, and seems to have affinities with some of the ineso- 
zoic fossil genera. 
In Onychoteuthis and Teleoteuthis* the pen has a more or less lanceo¬ 
late form, with a small posterior hood or hollow cone, without a solid 
appendix. Gonatus and Lestoteuthis not only differ from Moroteuthis in 
the pen, but have four rows of serrated suckers on the ventral arms. 
The genus Ancistroteuthis (type A. Lichtensteinii ) agrees somewhat 
better in the form of the pen, which is widest near the anterior end, from 
whence it tapers back to a long and oblique, compressed, posterior, 
hollow cone, but without a solid appendix at the end. It has numerous 
longitudinal nuchal crests, like Onychoteuthis. 
It is not improbable that it may become necessary to establish a dis¬ 
tinct family for Moroteuthis , when its armature becomes known. In that 
case the family should be called Moroteutliidce. 
LESTOTEUTHIS Verrill, 1880. 
The characters of Lestoteuthis Kamtscliatica, which I proposed to take as 
the type of this generic group, are not yet fully known. The peculiari- 
* This name is proposed as a substitute for Onychia Lesueur, 1821 ( non Hubner, 1816). 
The type-species is T. carribwa (Les., sp.). T. platyptera D'Orb. aud T. Krohnii Verany 
appear to be additional species.
