teeth may be only a sexual character ; but they are so similar to the 

 differences that I observed in the skulls of the Dolphins sent from 

 Liverj)ool that came from different localities, and had such a different 

 system of coloration, that I am inclined to regard them as distinct 

 for the purpose of attracting attention to them, and in the hope that 

 Mr. Layard, or some naturalist in the southern hemisphere, may 

 obtain a series of specimens, and be able to study the question in 

 more detail. 



The shorter-beaked sj)ecies of Clymene are chiefly known from 

 Layenorhi/nchtis by the convexity of the upper surface of the beak, 

 and of the intermaxilla above that surface.

ACANTHOPTERYGII. 

 Berycid^. 



Uhynchichthys ornatus, sp. nov. 



D. 12/J. P. 15. V. 1/G. A. 4/9. C. 15. L. 1. 36. L.tr.34/6. 



Length of specimen \-f^ inch. 



Length of head j, of pectoral i, of base of dorsal spines ^, of base 

 of dorsal rays y^ij, of base of anal \, of caudal i of the total length. 

 Height of head ^, of body g, of dorsal spines \, of dorsal rays \, of 

 ventral i, of anal spines i, of anal rays y\j of the total length. 



Etjes. Large, circular, diameter f of length of head, rather above 

 ^ a diameter from end of snout, nearly 1 diameter apart. 



Appearance percoid ; the dorsal profile much more convex than 

 the abdominal, which is nearly horizontal from the lower surface of 

 the snout to the inferior margin of the caudal fin. 



Mouth below, posterior to the produced and pointed snout. The 

 posterior extremity of the maxilla extends to beneath the centre of 

 the orbit ; it is hidden by the prseorbital. PrBeoperculum, its vertical 

 limb with fine but distantly placed serrations ; a large and strong 

 spine extends from its angle to the base of the pectoral fin ; its hori- 

 zontal limb strongly denticulated, as is also the lower margin of the 

 interoperculum. Operculum with two spines, the upper the largest, 

 its lower margin denticulated. Praeorbital and shoulder-bones ser- 

 rated. The upper surface of the head roughened by raised longi- 

 tudinal ridges. 



Teeth. Villiform in jaws, vomer, and palatines. 



Fins. Dorsal fins connected ; spines moderately strong, the second 

 the longest, whence they decrease to the last ; interspinous mem- 

 brane deeply cleft. Pectoral rounded. Ventral arises a little dis- 

 tance posterior to the pectoral, its spine being equal to the second 

 of the dorsal fin in length. Third anal spine longest and strongest, 

 the first very minute. Caudal slightly lobed.
