(pl. 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 Aètobatis narinari belongs to 
the American form, which there is every reason to think was redescribed by Duméril 
as A. latirostris’ ai\di by Gill as A. 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 Raja flagellum, and corresponds very 
closely with the description of that species given by Müller and Henle ( ‘ ‘ Plagiostomen, ’ ’ 
p. 180). I therefore recognize the following species in the genus : Aètobatis narinari 
(Euprasen), A. guttata (Shaw*) and A. flagellum (Bloch and Schneider). Possibly others 
exist.

' See Shaw’s General Zoology or Systematic Nahiral History, vol. v, partii, p. 285 (1804). Shaw did 
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.
