CEPHAIvOPODA OF THE HAWAIIAN ISEANDS. 
321 
In addition to the specimen above described, the Albatross collection contains three other indi- 
viduals which are so badly macerated (as though taken from the digestive cavities of larger animals, as 
was undoubtedly the case) that their true identity was not ascertained for a considerable length of time. 
One of these is a male and has been made the subject of the following notes; 
Male : Third arm pair very much larger than the others, bearing two or more very greatly enlarged 
basin-shaped suckers (pi. L, fig. 4) at their distal ends. No evidence of hectocotylization visible 
except that the left dorsal arm is much smaller than the right and is closely rmited witli its neighbor of 
the second pair by a very narrow basal webbing; no true fusion of the arms on either side can be made 
out after the fashion described for H. dispar. 
The firm adherence of the mantle and body just back of the nuchal cartilage is very clearly evident 
in this specimen. 
The extremely desiccated condition of the specimen precludes the giving of more accurate or com- 
plete details.

Remarks. — The only other species of this genus which are at present recognized are the H. dispar 
(Riippell) of the Mediterranean region and H. ineberi Joubin from the Dutch East Indies, from each of 
which H. hawaiiensis app&axs clearly distinct. Its nearer relationships are certainly with H. dispar, but 
it is to be differentiated on the following grounds: 
1. Indications of the presence of a ventral shield similar to that already familiar in Nectoteuthis and 
Stoloteuthis , but much less clearly defined. 
2. The complete concealment of tire funnel by the ventral lobe of the mantle. 
3. The heavy oblique folds on the under surface of the head which apparently function to secure a 
more perfect application of the mantle margin to the head and thus serve as a secondary locking apparatus. 
4. The curious nonconformity between the dorsal and ventral halves of the body in mature females. 
5. The shorter arms. 
The adults of this species are very neat, compact little creatures of pleasing appearance, and like all 
their near allies are probably quite brilliantly colored when living. They also possess luminous proper- 
ties, the photogenic glands overlying the ink sac in the present species being in all respects closely 
similar to those described for H. dispar and very conspicuous even in the macerated specimens.
