Hub. ad Pegu. 



A pretty little species, with no very marked character, re- 

 ceived by Mr. Theobald with the last from the neighbourhood of 

 the town of Pegu. It is a single specimen, like the other. 



Mr. Theobald has, during the late rainy season, verified the 

 occurrence of Pupina imbricifera, B., at Teria Ghat, on the 

 ascent of the Khasia Hills from Sylhet. In its operculum he 

 finds the corkscrew formation observable in those of the oriental 

 Megalomastomata and Cataulus. The shell occurs infrequently 

 on dead boughs of trees. A fine Cyclophorus which he got at 

 the same place and at Lacat, proves to be C. Siamerisis, Sowerby, 

 the received habitat of which may consequently, in the absence 

 of direct testimony to its occurrence in Siam, be subject to 

 doubt. Both Cyclophorus Pear'soni, B., and its variety C. Ben- 

 soni, Pfr., have been taken by Mr. Theobald on the southern 

 face of the Khasia range at Lacat and Chaila, and by Capt. 

 Rowlatt at the northern base of the same mountain group, in 

 Assam. If C. Siamensis should have an equal range, the more 

 widely known country of Siam may, from the similarity of 

 sound, have been substituted for Assam. Geographical specific 

 names are better avoided in cases where the collector has not 

 verified the alleged habitats personally. A Helix inhabiting 

 China has been called SenegalensiSy and a bivalve, alien to Gan- 

 getie India, has been called Bengalensis, — the specimen having 

 been merely purchased in the Calcutta Bazaar, which derives its 

 supplies of shells mainly from the boats of the Maldive islanders. 



Another shell found at Teria Ghat proves to be a dwarf variety 

 of Pterocyclos Albersi, Pfr., the habitat of which was previously 

 unknown. It is noted as "not common" by Mr. Theobald, 

 who obtained Pt. hispidus, Pearson, abundantly in the same 

 tract, as well as Hydrocena sarrita, B. Cyclophorus zebrinus, B., 

 was not common at Nanclai. 



The late researches of Mr. Theobald, aided in part by Mr. 

 Oldham in Ava, and the Messrs. Blanford in Sikkim, throw
