Achatina. 
Achatina tenwispira, Bens., of small size, is common at Akoutoung 
and further south. A small variety of A. crassilabris, Bens., occurs 
in Arakan, and another form, perhaps distinct, but closely allied, was 
found in the Shan hills near Ava. The species of Achatina do not 
appear to be numerous in Burma; they attain their maximum in the 
Indian area in the Western Ghats, and the hills of South India and 
Ceylon, and their numbers diminish to the eastward. 
Vitrina, 
Vitrina prestans, Gould, differing in no respect from the Molmein 
shell, and V. gigas, Bens., equally identical with the Khasi form, are 
both met with throughout the Arakan hills, though sparingly. A 
smaller species, which I had looked upon as the young of V. gigas, 
has been correctly separated by Mr. Theobald, and will doubtless be 
described by him, 
Ennea and Pupa, 
Ennea bicolor was met with near Tongoop in Arakan, and at one or 
two places in Pegu. Asin many other localities throughout its wide 
range, it is a scarce shell. 
Pupa Avanica, Bens. occurs near Ava, I found it abundantly on a 
small hill, a few miles north of Mandélé. 
Streptaxis, 
Besides the species above described from Arakan, a smaller form 
occurs in Pegu, which I consider a variety of S. Andamanica, Bens., 
the only difference I can detect being in the sculpture, which is some- 
what finer in the Pegu shells. 
Hypselostoma. 
I have nothing to add to the particulars of the distribution of the 
two species of Hypselostoma beyond those given in a preceding number 
of these contributions, 
CycLostoMAcEA, 
Cyclophorus. 
In the Shan hills east of Ava, I found two forms of large turbinate 
Cyclophori, one apparently a variety of C. speciosus, Phil., the other 
so closely allied that I doubt if it is wise to describe it as distinct. 
C. speciosus does not appear to occur in Northern Pegu, but I found
