locality where H. Huttoni, Pfr., 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 E. 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 leiophis, but 

 which shews some differences in the internal plication, 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 Kkasi 

 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. 



Bulimus. 



A variety of the sinistrorse Bulimus Sinensis, Bens., measuring 26 

 millem. in length 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 12 J 

 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. pidlus, Gray, occurs near Ava ; but not, so far as I am aware, in 

 Pegu. Specimens of B. ccenopictus, Hutton, were also met with in 

 Upper Burma. B. 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.
