68 CLARIAS SALAE. 



are of larger size and less in number than in either of 

 the two other species referred to. The fin-formula is also 

 constantly different ; of the three specimens two have : A. 

 '/jj , one: A. ^J^q', all agree in having fifteen soft rays in 

 the dorsal. 



The transverse bands are also differently distributed : they 

 are continued down to the inferior margin of the belly and 

 never bend backwards in their dorsal half as I find they 

 do in all the specimens of C. mossambicus I was able to 

 examine. Moreover the distribution of colours on all the 

 vertical fins appear to be different , as is the dark colour 

 of the belly in front of the pectorals. Of even more im- 

 portance is the large number of rows of scales under the 

 eye; though generally five, I count six rows on one cheek 

 of one of the specimens.

This species differs from the other African representa- 

 tives of the genus by the following constant characters. 

 The dorsal fin has from 89 to 91 rays, the anal from 70 

 to 74, a larger number than is found in any of the other 

 Species. In old specimens the length of the head is con- 

 tained six times and a half in the length of the body ; 

 in young ones five times and a half. The caudal fin is 

 contained once and a half in the length of the head. The 

 anal fin terminates just a little in front of the end of the 

 dorsal. The extremity of the pectoral fin is separated from 

 the beginning of the dorsal by an interspace equal to half 

 its length. In adult specimens the upper surface of the
