This species differs from S. elegans by the characters indicated in the subjoined 
synopsis of the species. It has decided affinities to Crossobamon eversmanni, Boettger. 
Nothing is known regarding its habits. The specimens were collected for me by 
Professor Petrie, while he and his staff were engaged excavating on the plain of 
Tel el Amarna. 
As has already been stated, it has been found at Bou-Saada, in Algeria, close on 
2000 feet above the sea ; at Batna (3350 feet), and also between Batna and Biskra. 
The latter place, on the margin of the Sahara, stands only 360 feet above the sea, and 
the oasis of Tuggurt, at about the same altitude, is distant only 136 miles due south. I 
am further indebted to the courtesy of Mr. Boulenger for the opportunity of examining 
a specimen of this species collected by M. Lataste at Mairer, on the way between Biskra 
and Tuggurt. Moreover, Dr. Franz Werner's description of the Stenodactijlus obtained 
by him between Mairer and Tuggurt suggests the probability that it also is this species. 
The only other example that I have seen is the one from Egypt, preserved in the 
Paris Museum, and figured by Dumeril and Bibron. 
The following is a synopsis of the species : —
