A sliort vertical fold of the skin at the lower part of the base of 

 the pectoral ; the coracoid is below the level of the iipper margin of

a-h. Two inches long. From Mr. Gerrard's Collection. 



The head and the anterior part of the body are very broad and 

 much depressed ; the head is as broad as long, with its profile semi- 

 elhptical, the snout being obtuse and rounded. The crown of the 

 head is quite flat, the upper profile sloping downwards in a gently 

 curved line from the forehead to the snout ; the width of the inter- 

 orbital space equals the diameter of the eye, which is two-ninths of 

 the length of the head. The cleft of the mouth is horizontal, curved, 

 of moderate width, extending behind the anterior margin of the eye. 

 The lower angle of the opercular apparatus terminates in a slender 

 acute spine. There are four short incisors on each side of the lower 

 jaw ; they are separated from the conical lateral teeth by a larger 

 canine-Hke tooth. GiU-apparatus as in the preceding species. 



The distance of the origin of the dorsal fin from the caudal is two- 

 fifths of its distance from the snout ; caudal rounded ; the anal com- 

 mences below the third dorsal ray and extends a little more back- 

 wards than the dorsal. 



Colour uniform reddish.
