of the Bay of Bengal. 199 



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 Centroiyristis ■investigatoris, sp. n,, and Trigla hemi- 



stictttj Sclilegel ; 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 afKnitics with Oneirodes from 



the Greenland Sea is another remarkable illustration of the 



wide range of distribution of the true deep-sea fishes.
