1, 4. V. monticola, Benson, MSS. in Pfeif. Mon. 
Helic. vol. 2, p. 497 : Knst. ed. Chemn. Yit. pi. 2, 
f. 6, 7, 8.-—Reeve, Conch.. Icon. Vit. f. 11. 
Landour, II imalayah. 
The surface is highly polished. 
2, 3. V. cassida, Hutton and Benson, J. Asi. Soc. 
Beng. vol. 7 (1838), p. 214.—Pfeif. Mon. Helic. 
vol. 3, p. 2.—Reeve, C. Icon. Yitr. 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 striae. 
5. V. venusta, Theobald, J. Asi. Soc. Beng. 1870, 
vol. 89, 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). 
Hengdan Peak, JST. Cachar Hills 
7. V. Birmanica, Philippi, Zeits. Malak. 1847, 
p. 65.—Pfeif. Mon. Hel. vol. 2, p. 498.—Reeve, 
Conch. Icon. Vit. f. 59. 
Mergui, Birmah. 
Our drawing is from the same shell figured by 
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, II. 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. 
Darjiling. 
10. V. membranacea, Benson, An. Fat. H. 1853, 
ser. 2, vol. 12, p. 93.—Pfeif. Mon. Helic. vol. 4, 
p. 792.—Reeve, Conch. Icon. Yit. 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 lxxv, cx. 
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 Goliah (pi. 
j 72, f. 3), and the young may prove the too briefly 
described M. humerosa of Gotdd, from Manlco, Tavoy 
(Proc. Bost. Fat. II. 1847, vol. 2, p. 219). 
2. M. prsemordiea, Tryon, 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 Tryon’s outline. 
3. M. pagodula, Gould, Proc. Bost. J. Fat. H. 
1847, vol. 2, p. 219 ; Otia Conch, p. 200.—Reeve, 
Conch. Icon. Io, f. 10 (as Io). 
Thoungyin River (branch of Salwen), 
Birmah. 
Our figure is taken from the supposed type in the 
British Museum, purchased from II. 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.
