SCHILBE. 315 



generally applied to this species throughout the whole of Egypt, but, properly 

 speaking, it is the plural form of the word, while " shilhyer " is the singular. 



There is a little bronze model in Mr. Hilton Price's collection (No. 2717 of his 

 Catalogue) which I believe to represent this species. Very good representations of 

 the fish occur in the fishing-scene in tomb 15 of the Pyramids of Sapara* and in the 

 tombs of Aba and Zau, Deir-el-Gebrawi f.

This species is closely related to and agrees in most respects with the preceding, 

 from which it is to be distinguished by the following characters : — The upper profile of 

 the head is nearly horizontal, the nape ascending very abruptly from the occiput to the 

 dorsal fin; the eye is larger and supero-lateral in position, its diameter contained four 

 and a half to five and one-third times in the length of the head in the adult, once and 

 two-thirds to twice and one-third in the interocular width, the latter being less than 

 the width of the mouth ; maxillary barbel not half the length of the head in the adult. 

 Anal fin with 67 to 75 rays. Caudal fin with rounded or obtusely pointed lobes. 



The coloration in fresh specimens is described by Ruppell as silvery, with the back 

 steel-blue and the head sea-green ; fins flesh-coloured ; a more or less distinct brown 

 streak on the upper lobe of the caudal fin ; iris yellowish brown. Young specimens 

 sometimes with a dark lateral band and a black spot on the dorsal and pectoral fins. 



Total length 330 millimetres. 



KiippelTs original specimens were obtained on the Cairo fish-market, but the fish is 

 evidently a rare one in the Lower Nile. Specimens were obtained in the Upper Nile, 

 in the Blue Nile, in the White Nile, and in the Bahr-el-Gebel by Petherick and by 

 Mr. Loat. Pfeffer's S. emini, which is probably not separable from S. uranoscopus, is 

 based on an example from the Muhale, a stream in Uniamwesi ; a second specimen, 

 from the Ganana River, has been referred to it by Vinci guerra.
