■ From this list it may be seen that of the fifty- three di.stinct species here recognized 
as occurring in Indian seas, no less than thirty-three have been taken during the pa.st 
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 Ceratopteridæ) are surface 
forms and would not usually be taken in a trawl . In the list 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 Ifioyd- 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. 
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 analysis, postea) and the flesh of the young 
is edible, although there does not seem to be much demand for it.
