V. FOUR NEW SPECIES OF AULACOBOLUS 
POC. .(DIPLOPODA: SPIROBOLIDAE) 
FROM INDIA. 
By F. SILvEsTrI. 
The genus Aulacobolus was proposed by Pocock ! for Sp/rvabo- 
lus uroceros, Poc , from Madras and up to the present comprises 
in addition only Sfirobolus thurstont, Poc., also from Madras. 
Mr. F. H. Gravely has sent me specimens of two species collected 
at Kavalai and Mr. L. Newton specimens of two more collected on 
the Pulney Hills. Exainination of this material his shown that 
the four species received by me are distinct among themselves 
and from the species named by Pocock, they are therefore des- 
cribed here as new. 
It is worthy of record that the species of Aulacobolus are all 
from Madras and South India, as are also the two species of 
Eucentrobolus, Poc., a genus distinguished from Aulacobolus only 
by the very strange sculpture of the body. 
Aulacobolus excellens, sp n.
