5. Station 103.— 2nd April, 1890. 



Off ]\ra(lras coast, lat. 15° 14' N., long. 81° 9' E. Depth 

 12G0 fathoms. Bottom blue miuL 



Temperature at surface 86° Fahr., at bottom 36° Fahr. 



In the trawl-bag were two fishes of different species, both 

 quite dead. 



§2. Revieio of the Collection, loith 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 wdiich, however, 

 were from the sandy bank at Station 96. They fall into 

 twenty-four species, of wliicli 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 thii'teen 

 genera into which the undescribed species full, five have been 

 founded upon sujiposed 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 investigatorisj 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.
