1 . AbrostomuB umbratus. 

 Sjnith, I. c. pi. 12. fig. 1. 

 Scales very small. The height of the body is nearly equal to the 

 length of the head, and a little more than one-lifth of the total 

 (without caudal). {Smith.) 



Streams north of Orange River. 



2. Abrostomus capensis. 

 Smith, I. e. fig. 2. 

 Scales small. The height of the body is equal to the length of the 

 head, and two-ninths of the total (without caudal). (Smith.) 

 Cape Colony. 



To this genus probably belong Labeo cnffer from the Great Fish 

 Elver and Uiheo sicheli from the Orange Eiver, very insufficiently 

 noticed by Castelnau, Poiss. Afr. Austr. p. 60. They are said to 

 have only one small barbel at the corner of the mouth.

 t The division named Garra by Hamilton Buchanan is an odd compound, 

 without any claim to anything like an artificial or natural genus ; it thus happens 

 that one of the species is a Discognafhus. which induced Dr. Bleaker to supersede 

 a most appropriate name given to a most natural genus by the barbarous deno- 

 mination Garra !
