This shell may at once be distinguished from the Burmese 

 H. Petasus, B., and the allied forms, by the white, thickened, 

 and expanded inner edge of the peristome, the sinuate basal 

 margin, and the somewhat wide superior margin of the aperture. 

 A single specimen was sent by Mr. W. Theobald for examina- 

 tion, without any indication of the locality, which may possibly 

 be Burmese. 



6. Helix fritillata, B., n. sp. 



H. testa perspective umbilicata, depresso-subconoidea, arcuatim cos- 

 tulato- striata, subtus lseviore polita, superne striis conf ertis sjiirali- 

 bus impressis decussata, interstitiis couspicue quadrato-granulatis, 

 pallide cornea ; spira convexa, subconoidea, apice obtuso, laevi- 

 gata, sutura profunda ; anfractibus 6, angustis, lente accrescenti- 

 bus, convexis, ultimo demum latiusculo, extus depresso, antice vix 

 descendente, subtus valde convexo, circa umbilicum excavato ; 

 apertura obliqua, oblique semiovato-lunata, peristomate superne 

 tenui, valde arcuato, subtus breviter expansiusculo, arcuato, extus 

 marginato, marginibus remotioribus. 



Diam. major 13, minor 12, axis 7 mill. 



Habitat in regione Peguensi. 



A single specimen, belonging to the Museum of the Asiatic 

 Society of Calcutta, was received for examination. 



In the ' Annals of Natural History ' for September 1860, 

 Helix consepta, B., was founded on a single specimen found at 

 Damatha, near Moulmein, by Major Haughton. I have since 

 found a specimen of the same shell in Col. Robert Gordon's 

 collection, made at Moulmein ; and a dwarf variety from Pegu 

 belongs to the Museum of the Asiatic Society of Calcutta. 



7. Helix phyllophila, B., n. sp. 



H. testa vix perforata, trochiformi, tenui, superne sericea, oblique stria- 

 tula, subtus subnitente, utrinque (sub lente) striis confertissimis 

 undulatis minutissime ornata, translucente, pallide cornea ; spira 

 conica, apice acutiusculo, sutura impressiuscula ; anfractibus 6|, 

 convexiusculis, ultimo carinato ; apertura obliqua, subquadrato-
