by the iirreorbital. The anterioi" margins of the mandibulary bones 

 form a rather obtuse angle ; the cleft of the mouth is more than 

 twice as broad as it is deeji ; the space at the 

 eliin, between the mandibularies, is short, 

 lanceolate. Eye with a very distinct poste- 

 rior adipose membrane, which extends nearly 

 to the pupil. There are twenty-one scales 

 between the snout and the dorsal fin ; the 

 ninth, the eleventh, the twenty-second or 

 twenty-third scales of the lateral line corre- 

 spond to the extremity of the pectoral and to 

 the origin of the two dorsal fins. The root of 

 the pectoral is on the middle of the depth of 

 the body, that of the ventral midway be- 

 tween base of the pectoral and dorsal. The 

 soft dorsal and anal scaly ; the origin of the dorsal is in the vertical 

 from the third soft anal ray.

Erom the Collection of Messrs. von 



I have ascertained by dissection that the number of the soft anal 

 rays is nine, and not eight as stated by Buchanan Hamilton. AU 

 the specimens of this species in the Collection of the British Museum 

 are from four to five inches long. The species, perhaps, does not 

 attain to a much larger size. The woodcut represents the head of 

 one of the typical specimens magnified twice the natural size. 



The fish called 31. parsia by Blocker has from forty to forty-five 

 transverse series of scales, and therefore cannot be identical with 

 oxir tyi)o.

The body is cylindrical anteriorly, and its height is contained five 

 times and a quarter in the total length, and nearly equal to the length 

 of the head. A posterior adipose membrane covers one-half of the 

 iris. The upper profile is curved ; the snout slightly convex, and not 

 shorter than the eye. The prseorbital has a deep notch anteriorly, 

 and does not cover the extremity of the maxillary. The upper lip 

 is rather thick. Doreal and anal fins equal in height ; pectoral 

 shorter than the head, the length of the snout not included ; caudal 

 as long as the head, emarginate, brown-edged. {Bl.')
