Tracheloteuthis, though in 
many points agreeing with 
topsis, is, I think, better placed now by Hoyle among the 
Ommastrephidse. 
Verania sicula (Krohn). PI. VIII, figs. 1 — 3. 
In its main features this species resembles Enoploteuthis, 
e. g. shape of fin and suckers modified into hooks, and is 
classified together with Enoploteuthis. The specimens studied 
by me were sent from Messina by Professor Kleinenberg to 
Professor Lankester. 
The arms, according to length, are 2, 3, 1, 4. Each arm has 
at its extremity a small swelling preceded by eight to ten pairs 
of modified suckers, and according to Pfeffer (10) these are 
hectocotylized portions, just as we find them on the fourth 
pair of arms in Enoploteuthis. 
The tentacular arms are very short and thin, and the club 
bears only a few suckers, three of which are relatively very 
large. These suckers are narrow, but do not bear hooks 
(fig. 3). 
The tentacular arms were not observed by Riippell or Krohn, 
and Verany thought that they were regularly lost at a certain 
stage. 
The specimen I examined was very much smaller than those 
previously described, and probably still quite young. Brock
