94 Contributions to Indian Malacology. [No. 2, 
locality where H. Huttoni, Pir., is found, I met with an intermediate 
variety, between the carinate form and the typical H. hariola. 
The Plectopylis group is represented near Ava by H. perarcta, de- 
scribed above, and further south by H. leiophis, Bens. This shell 
occurs near Thayet Myo, but I found it abundantly only at Akou- 
toung. Another form, which may be a small variety of lecophis, but 
which shews some differences in the internal pligation, also occurs 
near Thayet Myo. At Prome, close to the Pagoda, I found H. Fed- 
deni, (described above) which, however, appeared very rare, as I only 
obtained two perfect specimens, despite much search. 20 or 30 miles 
south of Akoutoung, I found H. Karenorum in abundance, and 2 or 3 
specimens of the large variety of the same shell still further south in 
the Arakan hills, nearly due west of Henzada. Elsewhere in the 
Henzada district and throughout Bassein, no species of the Burmese 
form of Plectopylis was met with, but the Himalayan and Khasi 
H. plectostoma, Bens. abounded south of the town of Bassein in sever- 
al places, Pyema Khyoung, Long Island, &c. It was also found by 
Captain Ingram in Arakan, near Tongoop. 
Bulinus. 
A variety of the sinistrorse Bulimus Sinensis, Bens., measuring 26 
millem. inlength and 15 in diameter, occurs near Prome. It has 
generally two dark stripes round the body whorl, but some specimens 
have other stripes, usually 3, above the periphery. Occasional speci- 
mens were met with further south. At Tongoop in Arakan, I found 
a much smaller variety, measuring only 20 millem. in length, and 124 
in diameter. At Akyab [I also found this small variety ; some shells 
being entirely yellow without any stripes, like Mr. Theobald’s Mergui 
specimens. 
B. putus, Bens. is rather common at Akoutoung, less so at Thayet 
Myo, and scarce to the south: I found it, however, occasionally, in the 
Bassein district. 
B. pullus, Gray, occurs near Ava; but not, so far as I am aware, in 
Pegu. Specimens of B. cenopictus, Hutton, were also met with in 
Upper Burma. JB. gracilis, Hutton, occurs throughout Burma appa- 
rently. I have found a rather dwarf variety in Ava, Pegu and 
Arakan, and have received it from Molmein.
