REPORT ON THE FISHES TAKEN BY THE BENGAL 

 FISHERIES STEAMER "GOLDEN CROWN." 



PART IL— ADDITIONAL NOTES ON THE BATOIDEL 



By N. Annandai^e, D.Sc, F.A.S.B., Superintendeiit, Indian M^iseum, 



Since my report on the Batoidei was published {Mem. Ind. Mus., ii, pp. i — 60), 

 a considerable number of interesting specimens of this group have been obtained by 

 the " Golden Crown," whose operations have now been brought to a close so far as the 

 Government of Bengal is concerned, and I have had the opportunity of examining 

 some of the Indian rays in the British and the Royal Scottish Museums. It has 

 therefore become advisable in some cases to supplement, and in one to correct my 

 former statements in the light of additional knowledge. I have nothing to add to 

 what I said as regards the Pristidae and Rhinobatidae, but the Trygonidae and My- 

 liobatidae need further comment, while as regards the Torpedinidae I may note that 

 a considerable number of specimens of Bengalichthys impennis of both sexes have 

 recently been taken in Balasore Bay, and one small female on the shore at Puri. 



My great and increased obligations in this work to Dr. J. T. Jenkins must be 

 acknowledged, and also my sense of the courteous assistance which I met in the 

 British Museum at the hands of Mr. G. A. Boulenger.

Bleeker's specimen of T. undulatus (one of the types of that "species") in the 

 British Museum (specimen M in Günther' s Catalogue) appears to be a young example 

 of T. uarnak in which the spots have already begun to coalesce. At this stage I am 

 unable to distinguish the colour variety variegatus from the typical form. Several of 

 the synonyms in the Catalogue must undoubtedly be transferred from this species to 

 T. gerrardii; but a more careful examination of Bleeker's specimens than I had time 

 to undertake in Europe would be necessary to elucidate this point fully. T. pareh 

 seems to me to be distinct from either species, although it is probably identical 

 with my own T. alcockii, which of course, should this prove to be the case, must be 

 sunk as a synonym. It may be noted that in dried or shrivelled specimens of 

 T. alcockii the flat scales on the dorsal surface become more conspicuous than is the
