Indian Deep-sea Fishes. 141 



Lithodes Agassizii, S. I. Smith (also from the Azores), 

 Pylocheles Agassizii, A. M.-Edw. (not elsewhere). 



And the following are common to the northern parts of the 

 North Atlantic and the Indian seas: — Nephropsis atlantica, 

 Norm an , and Calocaris Macandrece, Bell, the latter having 

 been also found at New Zealand. 



No nectic or abyssal species are included in this list. 



(e) Among the Mollusca, which have been identified by 

 Mr. E. A. Smith and Mr. E. S. Goodrich (Cephalopods), 

 4 out of 20 deep-sea species that are known to occur else- 

 where are common to India and the North Atlantic. They 

 are : — Solariella infundibulum i Watson (also occurs off the 

 Crozets), Puncturella asturiana, Fischer, Lucina spinifera, 

 Montagu, and Octopus januarii, Ststp., which last has also 

 been taken in the Eastern Pacific. 



Altogether, of the species that inhabit the moderate depths 

 (100-1000 fathoms) of the Indian seas and are also known 

 from corresponding depths elsewhere, ^j^jtha are known from 

 the Atlantic north of 10° S., and j^ths are identical with 

 species that also belong either to the deep fauna of the West 

 Indies and neighbouring coasts of America, or to the deep 

 fauna of the Atlantic approaches to the Mediterranean. 



This — which expressly excludes all true abyssal as well as 

 " Necton " species — is, so far as we know, a larger number of 

 thus limited deep species than the seas of India have in 

 common either with the basins of the East-Indian Archipelago 

 or with the seas of Japan, although it is interesting to note 

 that the affinities of the Indian with the Japanese deep fauna 

 are very well marked — 28 species being common to the 

 moderate depths of the two regions. 



For fuller details I would refer to a Report, now in the 

 press, upon the deep-sea Madreporaria dredged by the ' Inves- 

 tigator,' and to a paper (to be shortly published in the 

 ' Scientific Memoirs of the Medical Officers of the Army of 

 India ') summarizing the zoological observations of the 

 ' Investigator' between the years 1884 and 1897. 



To the list of Fishes common to the We3t Indies and the 

 Bay of Bengal and Andaman Sea must be added 



Bembrops gobioides (Goode) [= Hypsicometes gobioides, Goode, 

 =-Bembrops platyrhynchus, Alcock]. 



In the Indian Museum there is one of the ' Albatross' (?) 

 duplicates of Hypsicometes gobioides, presented to us by the 



Ann. & Mug. X. Hist. Ser. 7. Vol. ii. 11
