Color in alcohol greenish-olivaceous, pale or whitish below, and the 

 edge of each scale more or less tinted with dull coppery. A dull 

 purplish band running from the upper part of the eye, narrowly bor- 

 dered on each side, while on the head, with blue. It runs along the 

 base of the dorsal. A dusky purplish band runs from the side of the 

 snout through the eye to the base of the caudal above, and along the 

 side of the trunk it is very broad. A similar narrow band from the 

 pectoral along the lower side. A narrow pale dusky band starts above 

 the opercle and includes the lateral line till it descends posteriorly. 



'^ I have recently rejected Walbaum's name Raia birostris, adopting Raia 

 manatia of Schneider. A re-examination of Walbaum convinces me that the 

 word birostris is evidently a typographical slip, and that sucli names as he used 

 in the " Additamentum" are availaljle as binomials, for in every case a specific 

 name is italicised. The name Mobulidce should supersede Mantidce. See Science, 

 XVII, April 10, 1903, p. 594. 



^ Pennant says {Arctic Zoology, II, 1792, p. 377), under his discussion of Labrus 

 /imi«Za Linnaeus, that it inhabits the seas of Carolina, "as I suppose the three 

 former do," of whicli the one immediately preceding is Catesby's fish.
