(pi. x) accompanying the paper from which this quotation is taken is by no means 

 accurate but shows the white spots extending as far forwards as the spiracles and, 

 moreover, represents the snout as exceedingly short. 



It seems indisputable, therefore, that the name Aetobatis narinan belongs to 

 the American form, which there is every reason to think was redescribed by Dumeril 

 as A. latirostris and Ijy Gill as .4. laticeps. For the common Indian form, on the other 

 hand, the name A. guttata (Shaw)' is available. There is, however, a second Indian 

 form, much rarer than the first in the Bay of Bengal, which, in Mr. Boulenger's 

 opinion, is identical with Bloch and Schneider's Raia flagellum, and corresponds very 

 closely with the description of that species given by Miiller and Henle ( ' ' Plagiostomen , ' ' 

 p. 180). I therefore recognize the following species in the genus : Aetobatis iKirnuiri 

 (Euprasen), A. guttata (Shaw) and A. flagellum (Bloch and Schneider). Possibly others 

 exist.

 not distinguish the Atlantic from the Oriental species, and his figure of " Raja guttata " is quite 

 indefinite; but as he clearly meant to include the common Indian species in his description, his name 

 may stand.
