lviii INTKODTJCTION. 
Mr. Boulenger, in 1887 1 , mentioned incidentally that Professor Strauch had informed 
him that Scincus fasciatus=Scincopus fasciatus, Peters, occurred at Khartum. 
Strauch 2 , in his memoir of the Geckonidse, described a new genus from Egypt 
which he named Bunopus, and designated the species B. blanfordii. 
Lataste, in 1887, recognized a new genus of Elapine snake in a specimen that had 
been forwarded to him from Cairo by Dr. Walter Innes, who had purchased it from a 
snake-catcher, along with one or two other examples of the same serpent. This new 
genus he named Walterinnesia after its discoverer, and called the species cegyptia on 
the assumption that it was an Egyptian snake. 
Mr. Boulenger, in 1892 3 , described a new snake from Sennaar which had been 
regarded by Miiller, of Basel, as a variety of Eryx jaculus (Hasselq. & Linn.), and 
named it Gongylophis muelleri, ~B\gr.,=Eryx muelleri, Blgr. 
The same author 4 recorded Zamenis rhodorhachis, Jan, as an Egyptian species, one 
of the specimens in the British Museum having been obtained from Egypt so long 
ago as Wilkinson's day. In the same volume in which the foregoing species appeared, 
Lytorhynchus diadema (Dum. & Bibr.) also occurs as a snake found in Lower Egypt, 
the specimens having been obtained by me at Gizeh and Abu Roash. 
In 1893 5 , I described a species of Zamenis from Lower Egypt under the name of 
Z. rogersi, and, on the same occasion, indicated a new species of toad, Bufo pentoni, 
from the Suakin district. 
The second report on the additions to the collection of lizards in the British 
Museum by Mr. Boulenger was published in 1894 6 . In it one species new to the 
fauna of the Nile Valley in Lower Egypt is mentioned, viz. Tropiocolotes tripolitanus, 
Peters, the specimens recorded having been found by me at Gizeh. Another species 
new to the fauna of North-east Africa is also recorded, viz. Chalcides delislii, Lataste, 
which I found to be common at Suakin. 
In a preliminary list of the Reptiles and Batrachians of Egypt published in 1896 "', 
the following lizards were added to the fauna of Suakin, viz. Tarentola ephippiata, 
O'Shaughn., Latastia longicaudata (Reuss), Eremias mucronata (Blanf.), and Chame- 
leon basiliscus, Cope ; whilst the presence of the last named in the Delta of the Nile 
Valley, along with C. vulgaris (Linn.), was established. In the same list, Testudo ibera, 
Pallas, was indicated as being possibly present in the Sudan.
