1 6 GUDE : NEW SPECIES OF HELICOID LAND SHELLS. 



Diam. lo; alt. 5.75 mm. 



Hah. — Mount Mouleyit, Tenasserini, Burma. Type in my 

 collection. 



This is an interesting form of Sesara, allied to S. attaranensis, 

 Theob., which, however, is a much smaller shell. The new species is 

 further distinguished from S. attaranensis, by its semiglobular shape, 

 rounded whorls, deeply impressed umbilical region, and receding last 

 whorl. In the shape of the aperture, the form of the peristome, the 

 horseshoe-shaped fold on the basal margin, and the entering collu- 

 mellar fold, the two species are remarkably alike. Figure 7 (enlarged) 

 shows the aperture with its two folds. 



For both the shells here described, I am indebted to the kindness 

 of Colonel Beddome, whose MS. name of the latter species I have 

 had much pleasure in adopting. 



DESCRIPTION OF TWO NEW SPECIES OF 

 MICROPARMARION FROM THE ANDAMAN ISLANDS. 



By WALTER E. COLLING E, 



The Universi/y, Birmingham. 



(Plate i.) 



Hitherto the only reference to any Parmarion-\Wt molluscs in the 

 Andaman Islands, is a brief note by Lieut. -Col. Godwin-.A.usten^ in a 

 paper on the Land moUuscan fauna of these and neighbouring islands. 

 He there states that his brother and Col. Hobday found, when making 

 the ascent of Saddle Peak on North Andaman, a large slug-like form 

 resembling Girasia. The specimen, unfortunately, was accidentally 

 lost before they returned into camp. 



In the early part of last year Dr. O. F. von ]\Iollendorff sent me 

 two molluscs from the Andaman Islands, both of which belong to the 

 genus Microparmarion. 



I take this opportunity of expressing to him my best thanks, for so 

 kindly placing these very interesting molluscs in my hands. To the 

 Council of the Birmingham Natural History and Philosophical Society, 

 I also desire to express my best thanks for their kindness in defraying 

 the artist's charges in connection with the accompanying plate.
