of the Bay of Bengal. 
5. Station 103. — 2nd April, 1890. 
Off Madras coast, lat. 15° 14' N., long. 81° 9' E. Depth 
1260 fathoms. Bottom blue mud. 
Temperature at surface 86° Fahr., at bottom 36° Fahr. 
In the trawl-bag were two fishes of different species, both 
quite dead. 
§2. Review of the Collection , with List of the Fishes 
and Descriptions of the new Species . 
The number of specimens obtained in the above five hauls 
was considerably over a thousand, most of which, however, 
were from the sandy bank at Station 96. They fall into 
twenty-four species, of which nine (belonging to eight 
genera and six families) are already known, though rare ; 
while fifteen (belonging to thirteen genera and nine families) 
do not appear to have been yet described. Of the thirteen 
genera into which the undescribed species fall, five have been 
founded upon supposed generic types in this collection. To 
glance at the subject of distinction : while the fishes from the 
less depths (98 to 102 fathoms) mostly belong to well-known 
East- Indian genera, yet as exceptions we must note with some 
interest Centropristis investigatoris ) sp. n., and Trigla hemi- 
sticta , Schlegel ; those from all depths show, as would be 
expected, identities or marked alliances with the bathybial 
and hemibathybial forms of the seas of Aru, Banda, Celebes, 
&c. ; lastly, the discovery in the Bay of Bengal of a deep-sea 
Pediculate showing the closest affinities with Oneirodes from 
the Greenland Sea is another remarkable illustration of the 
wide range of distribution of the true deep-sea fishes.
