APPENDIX C.

At the beginning of the present century (1809) the grand work 
containing the discoveries and observations of the naturalists 
accompanying the French expedition to Egypt was published. 
(^^Description de FEgypt/^ Paris. Folio.) The ichthyological 
portion was worked out by Geoffroy St. Hilaire (father and son). 
It contains the descriptions and figures of twenty-seven species^ 
all from the lower parts of the Nile. The figures are productions 
of great artistic value^ though frequently inaccurate in points 
of detail. 
Not less important than the discoveries of the French naturalists 
were those made by Dr. Eduard Euppell_, who collected in Egypt_, 
on the Ped Sea^ and in Abyssinia;, in the years 1829 to 1835. He 
treats of the fishes of the Nile in three papers^ published in Frank- 
fort-on-the-Maine^ and gives a list of forty-five species^ thirteen of 
which were discovered by himself. Like his predecessors;, he col- 
lected chiefly on the Lower Nile ; but he added also six species from 
Lake Zana^ which we shall mention hereafter. Singularly enough_, 
these latter fishes have never been found in the Nile proper^* there- 
fore I need not add here their descriptions. 
Two French travellers paid some attention to these fishes almost 
at the same time as* Puppell. The first;, De Joannis^ appears to have 
collected chiefly small fishes^ which^ unfortunately^ are too much 
neglected by collectors;, who depend on the native fishermen^ and 
consequently obtain only the larger and eatable kinds. He de- 
scribes six species which have not been rediscovered, and are but 
indifferently described and figured in Guerin^s Magazin de 
* Lake Zana is 5,800 feet above the level of the sea, and tbe temperature of its 
water in March was 16*^ E. (Elippell.)
