According to Lleckel, whow T ell distinguished this species from L. niloticus, " Ilorie^ 

 is the name it bears at Assuan. According to Mr. Loat, it is not distinguished by 

 fishermen, so far as he could ascertain, from the " Labis," whose various names are given 

 under L. niloticus. 



L. horie is easily distinguished from L. niloticus by its more strongly fringed upper 

 lip, its higher and usually more convex dorsal fin with fewer rays, and its larger scales. 

 Out of thirty-six specimens examined, three have 12 branched rays in the dorsal fin, 

 twenty-eight have 13, and five have 14 ; seven specimens have 40 scales in the lateral 

 line, thirteen have 41, eight have 42, seven have 43, and one has 44; 16 scales round 

 the caudal peduncle occurs thirteen times, IS scales twenty-two times, and 20 only 

 once. 



L. senegalensis, C. & V., of which I have examined a good number of specimens 

 from the Senegal, the Gambia, the Niger, and Lake Chad, is extremely closely related
