ZOOLOGICAL LITEEATUEE. ]v 
J. E. Gray 1 , in 1845, recorded Agama colonorum (non Daud.), Gray,=J. spinosa, 
Gray, from Egypt, the specimens having been collected by Wilkinson and Burton. 
In the same year as Gray's Catalogue appeared, Eiippell published his Catalogue 
of the Reptiles in the Senckenbergian Museum at Frankfort 2 , the species enumerated 
having been chiefly collected by himself. Among the vipers we have the first instance 
of the presence of Bitis arietans in Kordofan. 
A. Dumeril 3 (1851) recorded the presence of Stemothcerus adansonii (Schweigger) 
and Cryptopus senegalensis=Cyclanorbis senegalensis (B.ScB.) in the White Nile, where 
they were collected by d'Arnaud ; and the existence of Chamceleon calyptratus, A. Dum., 
in the region of the Nile, whence it had been obtained by Botta. 
Rhachiodon abyssinicus, D. & ~Q.,=Dasypeltis scabra (Linn.), was mentioned for the 
first time from the Nile Valley in 1854 4 . The specimen was found by dArnaud on 
his expedition to the White Nile. 
Ulrich Jasper Seetzen 5 , the distinguished traveller, visited Lower Egypt and the 
Fayum, in 1809. He had apparently interested himself in the Reptilian and Batrachian 
fauna of the country, as the posthumous account of his travels that appeared, in 1855, 
mentions about ten species of snakes and two batrachians, chiefly under their native 
names, but unaccompanied by any exact description. 
Dr. Gunther 6 , in 1858, enumerated seven species of snakes from Egypt, collected by 
Wilkinson and Burton, and a specimen of Psammophis schokari, ForskSl, obtained by 
A. Lefebvre, but which he did not recognize as distinct from P. sibilans (Linn.). He 
likewise, in the same year 7 , recorded the presence of a new genus (Hemisus, Gthr.) 
of the Engystomatidse in Kordofan — the H. sudanense (Steindach.). 
In 1800, Jan 8 figured a Glauconia from Sennaar under the name of Ste?wstoma 
macrorhynchum= G. macrorhynchus (Jan). 
Peters 9 published, in 1862, a list of reptiles collected between Wadi Haifa and 
Sennaar by -Baron de Barnim and Dr. Hartmann and some others from "Egypt." The 
following were new to the Nile Valley : — 
Pelomedusa gehafie, Riippell. = Pelomedusa galeata (Schoepff).

Agama savignyi, non D. & B. = Agama hartmanni, Peters. 
Gerrhosaurus flavigularis, Wiegm. 
Lytorhynchus diadema, Dum. & Bibr. 
Crotaphopeltis rufescens, Boie. = Leptodira hotambmia (Laur.). 
Heterophis resimus, Peters. = Causus resimus (Peters) . 
Cystognathus senegalensis, D. & B. = Cassina senegalensis (D. & B.).
