MYRIAPODS FROM MESOPOTAMIA AND PERSIA, 
CoLLECTED BY Mr. P. A. BUXTON 
BY 
H. W. BroLeMann, Pav, FRANCE. 
(With two plates.) 
The material collected by Mr. P. A. Buxton, though limited to a few specimens, 
is far from being void of interest. 
A new Lithobiid has had to be inscribed to the Persian fauna. The redis- 
covery of Humbert and Saussure’s Strongylosoma persicum offered good oppor- 
tunity for describing the sexual characters of the female, which were still un- 
known ; such a type of vulva has not been observed before. The capture of a 
species of the genus Polyxenus, most likely to be P. ponticus, afforded the possi- 
bility of making up for the blanks of Lignau’s diagnosis. 
For the favor granted in enabling him to put on records such valuable speci- 
mens, the author wishes to express his sincerest thanks to Mr. Buxton.

An additional dorsal p exists on the 4th joint of legs of 2nd, 6th and 9th pair, 
but on one side only. No sexual structure on the last two pairs of legs, the last 
being somewhat swollen (vet not as much asin L. crassipes) and bearing a 
single claw.
