ZAMENIS DAHLII.

of the upper labials, post- and praeoculars. Under surface pale yellowish without 
spots. 
It attains to a length of 1080 millim., of which the tail forms 340 millim. 
In the great French work on Egypt the snake represented on Suppl. pi. iv. (1S13) 
figs. 4 1-43 is unquestionably a good figure of this species, which is not uncommon in 
Southern Europe, east of the Adriatic, and in South-western Asia. It has frequently 
been recorded from Syria and Palestine, but beyond the fact that the following unnamed 
figure occurs in the ' Descr. de l'Egypte,' leading to the supposition that the species is 
Eg. 10. 
Zamenis dcihlii, Eitz. 
Keproduced from Plate iv. fig. 4 (1813) of Eeptiles (Supplement), Deser. de l'Egypte. 
present in Egypt, not a single specimen, so far as I have been able to ascertain, has 
ever been recorded from that country before or since the day, in 1801, when Savigny 
and E. Geoffroy St.-Hilaire left the harbour of Alexandria for France. I have made 
very careful inquiries after it, but with no success. It may be very rare, or it may be 
confined to a limited area of N.E. Egypt, and thus have escaped observation ; but as 
four out of the six species of snakes figured on Suppl. pi. iv. have been found in 
Egypt, there is a reasonable expectation that it also will be rediscovered, and in order 
to facilitate its identification I have reproduced above a sufficient portion of Savigny's 
drawing to admit of the species being recognized by anyone who may be fortunate 
enough to find it.
