The collection described in this paper includes all the speci- 
mens of Cephalopoda (except shells of Nautilus) that have 
accumulated in the Indian Museum in the course of the last 
20 years, since Mr. Goodrich published his ‘‘ Report on the collec- 
tion of Cephalopods in the Indian Museum ”’ in the “‘ Transactions 
of the Linnean Soctety”’ in 1896. 
The Cephalopods in the present list have been taken in most 
instances by the ‘ Investizator’ off the Indian and Burmese coasts 
at depths varying from 5 to 947 fathoms, and in one instance a 
haul was made at 2000 fathoms. Reference to the text will show 
that many specimens were also collected on shore, and that the 
area covered extends from the Persian Gulf to China and Japan, 
and southwards to the Andaman Islands. It will be noted that 
many interesting specimens owe their capture to the energy of 
private collectors. Over four hundred specimens are enumerated, 
consisting of sixteen genera and forty-three species, only cne of 
which, a small Sepfza, appears to have been hitherto undescribed. 
There are also some specimens which are too young or in too bad 
a state of preservation for specific indentification. Over half the 
collection is comprised of individuals of Loligo indica, Pietfer, and 
Sepiella inermis (van Hasselt), in about equal numbers. Goodrich 
(1896) enumerates fifteen genera and twenty-eight species, five 
genera and twelve species of which are absent from the present 
list, but the results of both collections produce a total of twenty- 
one genera and fifty-five species. 
Of these genera Polypus comes first with twenty species, and 
it may be thought that the eighteen members of this genus noted 
in the present paper have been described at undue length, but 
anyone who has made a study of these creatures is aware of the 
difficulties lying in the path to correct identification and will not, 
I think, regret having as many details as possible, especially as it 
seems probable that future research may reduce the number of 
species ascribed to this genus. The Sepia family comes next with 
nine species. In this family so many differences occur in colour, 
surface and shape, from individual variation, and different modes 
of preservation, that in many cases specimens very unlike each 
other have proved to be the same species when the shell was 
examined. Measurements of a number of shells will be found in
