A well marked species, both, 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. lionesta of Gould. 



Besides the above described new species, Glessula Pegu,ensis, Gless. 

 Jiastula, (somewhat larger than the Sikkim type shell), Succinea semicerica, 

 Sesara Basseinensis, BZelicina Arakanensis, Bupina Blanfordi, Bterocyclus 

 parvus, several Alyccei and Diplommatince occurred on the Kumah hill and 

 near Mai-i in the Sandoway district of Arakan.

Having lately obtained additional specimens of Macroglossus spelceus, 

 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.
