Ceratoptera orissa. 



From this list it may be seen that of the fifty-three distinct species here recognized 

 as occurring in Indian seas, no less than thirty-three have been taken during the past 

 year by the " Golden Crown." Of the remaining twenty, seven probably live only 

 in water deeper than that in which the operations of the fishery steamer have been con- 

 ducted, while at least four (the members of the family Ceratopteridœ) are surface 

 forms and would not usually be taken in a trawl. In the Hst there are twenty-one specific 

 and two varietal names not to be found in Day's volume in the " Fauna," or there 

 regarded as synonyms. Of these, nine belong to species described within the last few 

 years by Alcock ' or I^loyd" and, with two exceptions, taken in deep water by the ' ' In- 

 vestigator," while twelve are here recorded for the first time or have recently been 

 recorded for the first time in the Records of the Indian Museum. A new genus, five 

 new species and a new variety are described in this report. 



Suborder BATOIDEI. 



Family PRISTID^ (Saw-fishes). 



The saw-fishes, which abound in the Bay of Bengal and make their way up some 



of the larger rivers, are very destructive to edible fish. Their livers yield an oil which 



should prove valuable (see Mr. Hooper's analysig, postea) and the flesh of the young 



is edible, although there does not seem to be much demand for it.
