ZOOLOGICAL LITERATURE. liii 
Giovanni Battista Brocchi 1 , a celebrated Italian mineralogist, was appointed by 
Mohammed Ali to be a member of the Scientific Commission attached to the Expe- 
dition which was dispatched, in 1823, for the conquest of Sennaar. He died at 
Khartum in 1826. In the Atlas to his posthumous work two lizards and two snakes 
are figured from that part of the Nile Valley. One of the lizards is Scincus officinalis, 
while the other figure suggests the Acjama described by Peters from Senaar, in 1862 as 
Agama hartmanni. One of the snakes represented is an Eryx, possibly E. muelleri, Blgr., 
but it is impossible to say what species the other figure depicts. 
Considerable uncertainty exists regarding the date of publication of the contributions 
of E. Geoff. St.-Hilaire, Is. Geoff. St.-Hilaire, and Victor Audouin to the first volume 
of the Natural History of the ' Description de l'Egypte ' which bears the date 1809. 
As the second of these distinguished men was born in Paris, in 1805, the fallacy of the 
date is self-evident; and as he was only made assistant to his father when he was 
nineteen years of age, the discrepancy between the date the volume bears and its 
possible actual date of publication is still further emphasized. A consideration of the 
literature of the period and a study of the evidence derived from the book itself by 
the passing references it contains to the literature of the time sanction the conclusion 
that Is. Geoffroy's portion was not completed before 1827 and that Audouin's Dart 
was not finished before 1829. 
E. Geoffroy's researches, and likewise Savigny's, were first carried on in the Delta, 
but were afterwards continued in Upper Egypt ; no details, however, are vouchsafed 
regarding the exact localities in which the specimens were found, except in two 
instances in which the two serpents are designated after the districts in which they 
were obtained.
