equally connected • P. Beguensu coming between P. artata and P.

P. Arula, B. P. Peguensis, B. P. Artata, B. P. Blmfordi, TL 



POMATIAS PEGTTEtfSE, Th. 



Testa auguste sive obteote umbilieata, turrita, costulate striata 

 translucente, flavescente-cornea. Apiee obtuse-, hevi. Anfractibus sep- 

 tern sive octo, tumidis, lente erescentibus. Apertura sub-eirculari. 

 Peristomate duplici, extra brevissime expanse., intus continuo, crasso 

 juxta suturam leviter inciso. Operculo tenui corneo. 



Long. 10. Lat. 8.5 mills. Apertura 2.5 mills. 



Habitat in monte marmoreo, cavernoso, hand procul a Gwa, pa^o 

 littore Peguensi. 



This Poinatias is accompanied at the Limestone hill near Gwa by the 

 following shells which I give to illustrate the range of some of them. 



Cyclophorus Theobalclianus, B. 



Leptoponia aspirans, B. 



Pupina artata, B. 



Alycseus seeptieus, Bl. 



Hydrocena pyxis, B. 



Diplommatina. 



Helicina. 



Pomatias Peguense, Th. 



Helix delibrata, B r 



H. textrina, B. 



H. honest a, G-ould. 



H. eastra, B. 



H. rotatoria, V. d. Busch. (small). 



H. baseunda, B. var. 



H. gratulans, Bl. 



Plectopylis plectostoma, B. 



Bulimus putus, B. (slender var.) 



B. gracilis, Hutton. 



Cryptosoma prsestans, Gould. 



Streptaxis Burmanica, Th. 



The Diplommatina I have not made out, as I got no good speci- 

 mens. The Helicina is very variable, and is I have no doubt H. 

 Andamanica, B. but two distinct varieties occur, differing chiefly in 

 size, and both smaller than the type, (as I regard it) from Port Blair, 

 but as some of these shells may have been described before, I refrain 

 from naming them. They are respectively five and six mills, diameter 

 whilst the type measures eight mills. From the Andamans, however, 

 I have a single small Helicina, smaller than either of those from the 

 mainland, and I believe all four forms are merely races, all merging 

 into each other, but my sole specimen has gone home to Mr. Benson, 

 who, from its vast discrepancy in size from the type he is acquainted 

 with, will probably regard it as a distinct species. Hand ego.
