ventral fins) more elongate/ and the space between the 

 pointed occipital process and the origin of the dorsal fin 

 greater (more than one fourth of the length of the head 

 measured to the extremity of the occipital process). These 

 two characters ought I think to enable anyone to identify 

 further examples, which I hope may soon turn up. In the 

 meantime I here give a description of the specimen for which 

 the British Museum is indebted to Dr. Warren: 



Depth of body 7^ times in the total length, length of head 

 4 times. Head once and ^ as long as broad, its upper surface 

 coarsely granulate ; occipital process angular; frontal fonta- 

 nelle nearly 4 times as long as broad, ^ the length of the 

 head ; occipital fontanelle very small, well in advance of the 

 occipital process ; eye very small, its diameter 4 times in the 

 length of the snout, 7 times in the interorbital width, which 

 equals the width of the mouth and -| the length of the head ; 

 band of premaxillary teeth 6 times as long as broad ; band of 

 vomerine teeth a little narrower than the premaxillary band, 

 rather widely interrupted in the middle, composed of small 

 partly pointed, partly granular teeth. Nasal barbel ^ the 

 length of the head ; maxillary barbel as long as the head, 

 reaching middle of pectoral spine ; outer mandibular barbel J 

 the length of the head, inner about h. (lill-rakers on first 

 arch long and closely set, 55 in number. Clavicles hidden 

 under the skin. Dorsal fin with 63 rays, its distance from 

 the occipital process -f- the length of the head, its distance 

 from the caudal fin 4 times the diameter of the eye. Anal 

 fin Avith 50 rays, narrowly separated from the caudal. 

 Pectoral fin i the length of the head, the spine feebly serrated 

 on the outer border, -i the length of the fin. Ventral fins 

 once and } as distant from the root of the caudal fin as from 

 the end of the snout. Caudal fin h the length of the head. 

 Dark olive brown above, whitish beneath. 



The type specimen, which measures only 480 millim., has 

 a rather larger eye, — its diameter 3 times in the length of 



' In CI. ifariepiniis the ventral fins are nearly equally distant from 

 the end of the snont and from the root of the candal fin.
