MACKOCHLAMYS. 141 



possibly be the same as the Himalayan H. vesicula. Hutton, who 

 was a very accurate observer, noticed the difference between 

 them : he says " they have no tentacular processes on the right 

 side, no fleshy hook on the tail." No. 6 Helix of a previous 

 paper in same Journal, February 1834, p. 83, was a Macrochlamys, 

 and is now known as M, petrosa : " shell is like No. 29, but is 

 more polished."

 Nanina (Macrochlamys) honesta, var. andersoni, Reeve, Conch. Ic. 



pi. 84, fig. 452 (as H. honesta) j Nev. Hand-list, i, 1878, p. 24. 



Original description : " This variety is distinguished (from 

 typical honesta) by its less depressed shape, it is scarcely if at all 

 angled at the periphery (the angulation being very distinct in the 

 type form), the peristome not being so broadly reflected over the 

 perforation ; the substance and texture, perforation, shape of the 

 aperture, and number of whorls are identical." 



Type of var. andersoniana from Ponsee (J. Anderson). 



Diam. 11, axis 6| ; apert. alt. 4, diam. 5^- mm. 



Nevill records: Hob. Thyetmyo, Sibsagur, Naga and Khasi 

 Hills, Chittagong and East Cachar, Dafla Hills, &c. 1 can only 

 accept his Upper Burmah localities : Pudupyoo, 2nd Defile Irrawady, 

 Nan din, and Ava. Specimens from Bhamo (Anderson) in my 

 collection do not agree with the Assam shells, and I doubt the 

 identification, many of the shells having been collected by and 

 known to me. The description of the Bhamo shell is as follows: 



Shell globosely and depressedly conoid, narrowly umbilicated, 

 rather solid ; sculpture very smooth and glossy, longitudinal 

 microstriation ; colour pale horny with a greenish tinge ; spire 

 moderately high, slightly convex ; suture adpressed ; whorls 4|, 

 sides above convex and well rounded on the periphery, the last 

 slightly descending ; aperture oblique, broadly lunate ; peristome 

 slightly thickened, straight, reflected considerably over the per- 

 foration. 



Size : major diam. 10-3, minor diam. 8-5; alt. axis 5'0, alt. body 

 whorl 4-0 mm. 



Having examined the animal of M. honesta from Moolayit, 

 Tenasserim, I have found considerable differences between it and 

 M. andersoniana, especially in the radula ; this last I consider a 

 good species. It was apparently this species, or one very like it, 

 which Stoliczka described in the Journ. Asiat. Soc. Bengal, 1871, 

 at the bottom of pp. 249-250, with the figures on pi. xvii. of 

 teeth of the radula, fig. 14, and the sperm atophore, fig. 13. 



No. 157. Macrochlamys beata, Godwin-Austen. 

 Teeth of radula are figured on p. 126, fig. 49 E.]
