In the original description, the anal fin is saitl to have 48 rays, but there must 

 have been incliuled by inadvertence the five rays of the right ventral fin, which is 

 continuous with the anal fin. There are 70 to 80 oblique rows of scales running 

 downwards and backwards above the lateral line. The blind side of the head in 

 advance of the preopercle, and the anterior rays of the dorsal and anal fins are 

 fringed with rows and clusters of filaments. These are not so long or so numerous 

 as in A.fonsecensis.

367. Symphurus atramentatus Jordan d- Bollman. 



Known from specimens dredged by the Albatross in Panama Bay at Sta- 

 tions 2795, 2797 and 2805, depths 33 to 51| fathoms; recorded by Garman (1899, 

 p. 229). 



368. Symphurus elongatus {Giinther). 



Occasional in the Panama market, reaching a large size, the largest specimen 

 seen by us being 255 mm. long. In adults, the depth is contained 3^ to 3| in the 

 length, thus much greater than has been ascribed to the species.
