2 Ergino River, tributary of Omo River, Malo, 3000 ft. — Zaphiro, 7.7.05. 



This large series has enabled me to ascertain the amplitude of variation in this 

 long-known but not at all well-known species. I have counted the dorsal fin-rays and 

 the scales in 140 specimens, and recorded the following variations: — 



One specimen (from the Sagan River) has 13 branched rays in the dorsal, thirty-one 

 specimens have 14 9 seventy-one have 15, thirty-five have 16, two have 17; 41 scales 

 in the lateral line occurs twice, 42 twelve times, 43 thirty- eight times, 44 seventy times, 

 45 eighteen times ; 8^ scales in a tranverse series above the lateral line one hundred 

 and thirty-one times, 9J nine times ; 8^ scales in a transverse series between the 

 lateral line and the middle of the belly fifty-nine times, 9J seventy-seven times, 

 10 three times, 10^ once ; 18 scales round the caudal peduncle twenty-three times, 

 20 one hundred and ten times, 22 seven times. 



To judge by the series collected by Mr. Loat, the species is more common in the 

 north than in the south, and Mr. Loat describes it as by far the commonest fish 

 between the mouths of the Nile and Haifa. 



The following list of native names is supplied by Mr. Loat, who observes that 

 L. horie is not, as a rule, distinguished from L. niloticus by the fishermen : — " Labiss" 

 (i^^J), at Cairo, Samannud, Lake Borollos, Lake Edkou, Beni Souef, Eosetta 

 (at Kafr-el-Zayat the words "labiss hdsharbie" refer to big "labiss")', " bessariya" 

 (jcj ,L*j), at Cairo, Barraga N. of Cairo, Eosetta, Kafr-el-Zayat, Assiut, Fayum, 

 Beni Souef, is used when speaking of small " labiss,' 1 also at Sohag, Akhmim, 

 Girga, Nag 'Hamadeh, Assuan ; " syrr " ( j*<*), this name is sometimes applied to this 

 species at Samannud, Lake Borollos (at Kafr-el-Zayat "syrr" applies to medium- 

 sized "labiss")', "hinnima" (<ujJ^), on and near Lake Menzaleh; "migwar" ( .|yu») 

 is the name given to big examples and " makaky" (&&«) to medium-sized examples in 

 the Fayum (the word " labiss" not being used in the Fayum at all); "labiss eraie" 

 (^M| jjd) is a name used by some of the fishermen at Beni Souef; "lips" ( L «J)
