 f. 6, 7, 8.— Reeve, Conch.. Icon. Vit. f. 11. 



Landour, Himalayah. 

 The surface is highly polished.

 Beng. vol. 7 (1838), p. 214.— Pfeif. Mon. Helic. 

 vol. 8, p. 2.— Reeve, C. Icon. Vitr. f. 10 (from 

 Benson's specimen). 



Himalayah. 



The surface is dull, and shows in the type here 

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

 faint and distant spiral strise. 



•5. V. venusta, Theobald, J. Asi. Soc. Beng. 1870, 

 vol. 39, pt. 2, p. 400. 



Aracan Hills, between Tongoop and Prome. 

 The aspect of the under side reminds us of a 

 miniature gigas. 



6. V. solida, Godwin-Austen, Proc. Zool. Soc. 

 1872, p. 518, pi. 30, f. 10 (as Helicarion).

 p. 65.— Pfeif. Mon. Hel. vol. 2, p. 498.— Reeve, 

 Conch. Icon. Vit. f. 59. 



Mergui, Birmah. j 

 Our drawing is from the same shell figured by j 

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

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

 pressa " is scarcely suitable for the specimen. 



8. 9. V. heteroconcha, H. Blanford, J. Asi. Soc. 

 Beng. 1871, vol. 40, pt. 2, p. 45, pi. 2, f. 8 (as 

 Helicarion).— Pfeif. Mon. Hel. vol. 7, p. 9.

 ser. 2, vol. 12, p. 93.— Pfeif. Mon. Helic. vol. 4, 

 p. 792.— Reeve, Conch. Icon. Vit. f. 78. 

 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. 



PLATE CLII I. 

 MELANIA. 



See previous plates Ixxi to Ixxv, ex. 



1. M. Reevei, Brot, Cat. Melan. 1862, p. 46, name 

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

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



Birmah. 



The type in the British Museum is an immature 

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

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

 described M. humerosa of Gould, from Manko, Tavoy 

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



2. M. praemordica, Try on, American J. Conch, 

 vol. 2, pt. 2, 1866, p. Ill, pi. 10, f. 3. 



Birmah, Pegu. 



Apparently very rare : our sole specimen was a 

 broken one ; so the outer lip has been corrected in 

 accordance with Tx'yon's outline. 



3. M. pagodtila, Gould, Proc. Bost. J. Nat. H. 

 1847, vol. 2, p. 219 ; Otia Conch, p. 200.— Reeve, 

 Conch. Icon. lo, f. 10 (as lo). 



Thoungyin River (branch of Salwen), 

 Birmah. 



Our figure is taken from the supposed type in the 

 British Museum, purchased from H. Cuming. 



4. M. Reevei, var. imbricata. 



5. 6, 7. All from the Shan province. Figure 6 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, but 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 to pronounce an opinion.
