20. Clarias btjogetti, sp. n. 



Vomerine teeth granular, forming a crescentic band which is as 

 broad as or a little narrower than the prsem axillary band ; the 

 latter about 7 times as long as broad. Depth of body 6| or 7 

 times in total length, length of head (to extremity of occipital 

 process) 3 or 3^ times. Head lg or lj as long as broad, very 

 feebly granulate ; occipital process angular ; frontal fontanelle 4 

 or 5 times as long as broad, its length about 4 times in length of 

 head; occipital fontanelle small, in advance of occipital process; eye 

 small, 3 or 4 times in length of snout, 5| to 7 times in interorbital 

 width, which nearly equals width of mouth and is contained 2^ or 

 2^ in length of head ; nasal barbel about | length of head ; max- 

 illary barbel as long as or a little shorter than the head (a little 

 longer in the young) ; outer mandibular barbel 1| or I5 as long 

 as inner, which measures \ or § length of head. Gill-rakers 

 closely set, about 40 on first arch. Dorsal 68 to 73, its distance 

 from the occipital process j? or ^ length of head, its distance from 

 the caudal fin greater than the diameter of the eye. Anal 46 to 

 50, narrowly separated from the caudal. Pectoral not quite | 

 length of head ; the spine serrated on the outer border, about § 

 length of the fin. Ventrals midway between end of snout and 

 caudal. Caudal \ length of head. Olive above, marbled with 

 black, white beneath ; anal with a light edge ; a blackish streak 

 from the angle of the mouth to the base of the pectoral. 



Total length 330 millim. 



Three specimens. 



Very nearly allied to C. senegalensis C. & V., with which it may 

 ultimately have to be united. The less rugose head and the 

 narrower frontal fontanelle are the characters which induce me to 

 regard it, provisionally, as distinct. 



" Called ' Connoconno ' by the natives. Often eaten by natives 

 but not much esteemed. Lives chiefly in shallow swamps,"
