The height of the body is a little less than one-fourth of the total 

 length (without caudal). The lower jaw is the longer ; the maxillary 

 barbels extend to the second third of the anal fin, those of the mandi- 

 ble are shorter than the head. Pectoral spine slender, smooth ; anal 

 not united with caudal. Body with irregular darker spots ; a blackish 

 blotch behind the gill-opening. (H. B.)

Vomerine teeth in two distinct patches (according to Bleeker, 

 Nederl. Tydschr. Dierk. 1863, p. 115). 



5. Callichrous anastomus.

 The height of the body is nearly equal to the length of the head, 

 and one-fifth of the total (with the caudal). The diameter of the 

 eye is one-fifth or one-sixth of the length of the head. The vomerine 

 teeth form two separate, narrow, transverse bands. The maxillary 

 barbels extend to the anal, those of the mandible to behind the orbit. 

 Pectorals shorter than the head : their spine is serrated, and equal 

 in length to the distance of the orbit from the end of the operculum. 

 Anal not united with the caudal. A blackish spot behind the gill- 

 opening. (Bl.)

The height of the body is contained five times and a third to four 

 times and three-fourths in the total length (without caudal), the 

 length of the head five times to five times and two-thirds. The dia- 

 meter of the eye is one-sixth or one-seventh of the length of the 

 head. Neck elevated, the upper profile obliquely descending, straight. 

 The lower jaw is the longer ; the vomerine teeth form a narrow band, 

 interrupted in the*middle. The maxillary barbels extend to the second 

 fifth of the anal fin ; those of the mandibles are about as long as the 

 head. Pectorals a little longer than the head, with a slender spine, 

 which is not denticulated, and equal in length to the distance between 



* This figure is not very accurate, the cleft of the mouth being produced back- 

 wards to below the eye, whilst in truth the eye is always behind the angle of the 

 mouth, even when the latter is opened. The anal and caudal also are entirely 

 disconnected in the figure, which does not agree with our specimen or with Dr. 

 Bleeker's description.
