THE FISHES OF MALABAR. 219 



I have named this fish after my excellent correspondent the Rev. H. Baker, Jan. who obtained 

 several specimens of it at Mundikyum, on the Travancore hills, where it grows to six inches in length. 



The Opsarius Malabaricus, Jerdon, from North Malabar, appears to be allied to this species, 

 but is much more beautiful in its coloration, and differs apparently in the number of rays, scales, 

 and position of the fins. 



Habitat— Hill ranges of Travancore, in South Malabar. 



Group DANIONES. 

 Genus PAEADANIO.* 



Branchiostegals, three. Body oblong, strongly compressed. Profile of back almost straight, that of 

 the abdomen very convex. Lips thin. Mouth antero-superior, cleft moderately oblique: the superior 

 jaws emargmate, the symphysis of the lower jaw hooked. Preorbital triangular, apex below. No cirri. 

 Eyes with free fids. Pharyngeal teeth in three rows, pointed and curved. Dorsal fin without scales at its 

 base; no hard rays to fin: it is situated behind the ventral, and its posterior portion is over the com- 

 mencement of the anal. Anal elongated, with more rays than the dorsal. Scales of moderate size, or 

 small. Lateral line strongly concave, situated near to the abdominal profile.

Length of head \, of pectoral \, of base of dorsal 1 of base of anal £, of caudal I of the total 

 length. Height of head \, of body I, of dorsal \, of anal } of total length. 



Eyes— Diameter J length of head, f of a diameter from end of snout, 1 diameter apart. 



Profile slightly raised to base of dorsal, from whence it gradually sinks to the caudal; the 

 inferior surface of the body much more convex than that of the back. The upper margin of the 

 lower jaw when closed is flush with the upper surface of the head. 



Mouth oblique. Lower jaw the longest; the extremity covered by a knob which is received 

 into an emarginate space formed by the intermaxillaries. Lips thin, covering the jaws. Preorbital 

 small, irregularly quadrilateral, the lower extremity the smallest, forming a sort of apex. Superior 

 margin of orbit close to profile. Upper surface of head nearly flat. Opercles smooth. 



Teeth— Pharyngeals curved and pointed : the external row much the largest— 5,4,1 I 1,4,5. 



Fins— Dorsal arises rather nearer to the snout than to the posterior extremity of 'the caudal' 

 but is entirely situated in the last half of the body; anal arises opposite the dorsal. Caudal 

 lobed. Pectoral just reaches the ventral, which does not extend to the anal. Anterior extremities 

 of the dorsal and anal the highest. Margin of dorsal convex, of anal slightly concave. 



* Dr. Sleeker having examined the species described in this work, considers that it might constitute 

 a sub-genus of his Danio, Ham. Buch. et Perilampus, Bleeker, and suggests that it might be termed 

 Paradanio, which may be distinguished from the Danio by the absence of cirri, and by the inferior jaw 

 having a more horizontal direction. As to my knowledge, this species is only one of a very large group in 

 Southern India, I have placed it in a distinct genus, which would come next to Dr. Bleeker's Danio.
