G. E. Dobson — On the Osteology of some species of Bats. [No. 4, 
A well marked species, botli by its peculiarly subcylindrial shape and 
by the denticulations of the apertural margins ; it is not uncommon on the 
Arakan coast.

Only the two figured specimens of this shell were found by Mr. Theobald 
at the above named locality. The species is intermediate between Blanford’s 
compluvialis and nebulosa, differing from the former by being somewhat 
depressed, by a comparatively slight sutural depression and larger umbilicus ; 
from the latter it differs by its polished surface, less numerous and regularly 
convex whorls, particularly at the periphery of the last. These differences 
also apply in a comparison with M. honesla of Gould. 
Besides the above described new species, Olessula Peguensis, Gless. 
liastula, (somewhat larger than the Sikkim type shell), Succinea semicerica, 
Sesara Basseinensis, Selicina Arakanensis , Papina Blanfordi, Pterocgclus 
parvus, several Alyccei and IJiplommatinm occurred on the Kumah hill and 
near Mai-i in the Sandoway district of Arakan.

Having lately obtained additional specimens of Macroglossus spelaeus, 
from Mr. Theobald,* I have been enabled to have a complete skeleton made 
from an adult male. 
As previously remarked by me, the index finger possesses no trace of a 
claw, but has instead a small, but distinct third phalanx connected with the

the description of the species was taken, were obtained by Dr. Stoliczka. (See Journ.
