Himalayah. 



The surface is dull, and shows in the type here 

 figured, not merely concentric folds, but, also, some 

 faint and distant spiral strise.

Aracan Hills, between 'f'ongoop and Prome. 



The aspect of the under side reminds us of a 

 miniature gigas.

Mergui, Birmah. 



Our drawing is from the same shell figured by 

 Reeve from the collection of Mr. Cuming, who, 1 

 think, had it fi-om the author. Yet the term " de- 

 pressa " is scarcely suitable for the specimen.

 Balcadara, Ceylon. 



Our figure is taken from the shell delineated by 

 Reeve, which has not arrived at the full size stated 

 by Benson, but is the only specimen attainable.

 for M. balteata. Reeve (not Phil.) Conch. Icon. 

 Melan. f. 144, b (scarcely 144, a). 



The type in the British Museum is an immature 

 form of the shell we had intended to call Goliah (pi. 

 72, f. 3), and the young may prove the too briefly 

 described M. hnmerosa of Gould, from Manko, Tavoy 

 (Proc. Bost. Nat. H. 1847, vol. 2, p. 219).

Apparently very rare : our sole specimen was a 

 broken one ; so the oviter lip has been corrected in 

 accordance with Tryon's outline.

Our figure is taken from the supposed type in the 

 British Museum, purchased from H. Cuming.

6, 7. All from the Shan province. Figure (3 is 

 the M. variabilis, var. turrita of Theobald in the 

 J. Asi. Soc. Beng. 1865 (vol. 34, pt. 2, pi. 9, f. 6 ; 

 f. 7 his variabilis, var. vittata (do. f . 4) ; f . 5 a 

 form somewhat allied to the first, bnt with many 

 more rows of granules. They may possibly all 

 be forms of baccata, or possibly all distinct species, 

 but pending the monograph of Melania by Dr. 

 Brot we will not venture topi-onounce an opinion.
