250 MELANIIDA. 
var. [P M. humerosa, Gould]. 
1 Ataran [Tenasserim Proy.]; ex c. Dr. F, Stoliczka, 
The whorls are markedly more convex in this specimen, and 
the spiral sculpture subobsoletely, but less unequally developed. 
Long 444, diam. 17{; not decollate. Gould compares his 
species with M. intermedia, Busch. 
38. Melania [Melanoides] tourannensis. 
Melania tourannensis, Souleyet, Voy. Bonite, 1852, Touranne, long. 51, diam. 
21 mil., decollate, 4 whorls. 
Unlike M. Brot, I consider the deflection of the columellar 
margin as an important character of this species; his pl. 11, 
fig. 3b, and pl. 14, fig. 2, may be compared. 
var. gloriosa. 
Melania gloriosa, Anthony, Amer. J. Conch, I, 1865, Pegu. 
6 Sandoway District, Arakan; ex c. Dr. F. Stoliczka, 
I have never seen as fine a specimen as that represented 
in the Con. Indica, pl. 72, fig. 2 [“ Bassein”’]; these Sandoway 
ones are intermediate between the above-quoted figure and 
fig, 6. Long, 66, diam. 303 mil. 
var, peguensis [ ? dist. sp.]. 
Melania peguensis, [Anthony], Hanley, Con. Indica, pl. 72, fig. 6. 
2 Henzada, Pegu [typical of var.]; exc. Dr. F, Stoliczka [72, 262}. 
Almost seems to me specifically separate. Besides the different 
shape of the whorls and aperture, the entire absence of the spiral 
sculpture of the typical form is very characteristic. 
var. compacta, nov. 
2 Henzada, Pegu; coll. Dr. F. Stoliczka, 
Long. 63}, diam. 234 mil.; decollate, of 5 whorls. 
This is the form nearest typical M. towrannensis, from which 
it principally differs by not possessing the excavation below the 
suture. Itis a still smaller and more compact variety than var. 
peguensis, with the spiral strice at base of last whorl very dis-
