This new species is to be distinguished from L. melanops, Newpt., apparently 
its nearest relative, by its rugose tergites and by the spinal armature of the legs. 
The only Lithobius so far recorded from Persia is L. persicus Pocock, 1899, from. 
Seir. The possibility of identifying the above described specimen with Pocock’s 
species is excluded considering that the latter has only the 13th dorsal plate 
angularly produced, that the anal leg is armed with O. 3. 3. 1 spines below, with 
a single apical claw and with a coxolateral spine, and that the legs of the two 
last pairs are sulcate above in the male. 
CHORDEUMOIDEA, sp. 
One female specimen from Resht; II, 1919. 
TULOIDEA, sp. 
One immature specimen from Resht; II, 1919. 
POLYXENUS PoNnTICUS (Lignau, 1903) nob. 
Length (without the anal bunch) 8, 50 to 9 mill. Breadth of the 7th segment 
(including pleurz) about 0.95 mill. 
In most of the morphological details the Persian specimens are identical 
with P. lagurus Latr. The sense cones of the palpi are single-jointed. Ocelli 
six. Sense calicles of the head disposed in a triangle as in the western species. 
Also the anal bunches are located alike. .
