THE BATKACHIANS OF EGYPT. 
" Similar to the typical form, but the marking on the loin is absent; the lateral streak 
frequently broken up into spots from the middle of the side." This description is 
based on individuals from the island of Elba, from the region to the east of the Levant 
as far as Resht in Northern Persia, and from the island of Hainan in the Chinese Sea. 
The description given by Audouin of Hyla savignyi differs but little from the characters 
usually found in the typical form, with the single exception that the marking on the 
loins is absent. No Egyptian example of this frog exists in any museum, so far as I 
am aware ; and as Audouin's description is the only one extant, the figure on which 
his account was based is here reproduced (fig. 14), as there is no evidence that he 
had a specimen before him when he wrote it.

I took a great deal of trouble, while in Lower Egypt, to try and discover this frog, 
but without success. I had a coloured drawing of it prepared and had it showed 
to many native gardeners in and around Alexandria, but not one of them 
recognized it. 
This variety is common in Palestine and Syria, and also to the west of Egypt, along 
the coast-line of the Mediterranean. It has also an extensive distribution over Asia, 
and occurs as far east as Japan.
