in which the granulation is not much developed, and in most other 
examples at the commencement of the chitinous margin of the 
last loculus. An examination of the arrangement of the various 
internal organsshowed, that, as Wiilker (op. c7#., p. 31) has already 
pointed out, this genus and Sefia resemble each other almost 
exactly as regards the anatomy.

Sepiella sp. 
(S. W. Kemp)—One. 
The above is too young to determine with certainty as it has 
a mantle-length of only 133 mm. Wutilker regards Sepia specimens 
with mantle of 27-40 mm. as too young to determine specifically. 
If, however, a number of specimens of large and small size occur 
together it seems possible to assign them specifically at a much 
earlier age. 
Family SEPIIDAE. 
M 5}9*5 ‘Investigator’ station 80: 17-i-1890, 4 miles S.E. of Sonapur 
Beacon, Ganjam Coast, 24 fathoms—Two immature. 
These have a mantle-length of 6 mm. The fins commence 
at 2 mm. from the mantle-margin and are most developed 
posteriorly. Fourth arms the largest and with keels; suckers of 
arms in two rows. Tentacles missing except for a retracted one 
which can be observed coiled round beneath the skin on the 
ventral surface. Colour buff, closely freckled with small purple- 
brown chromatophores, which are thickest on the median dorsal 
surface of the mantle and head.
