250 MELANIID^J. 



var. [? M. humerosa, Gould]. 

 1 Ataran [Tenasserim Prov.] ; ex c. Dr. P. Stoliczka. 



The whorls are markedly more convex in this specimen, and 

 the spiral sculpture subobsoletely, but less unequally developed. 



Long 44 J, diam. 17f ; 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 pi. 11, 

 fig. 3b, and pi. 14, fig. 2, may be compared. 



var. gloriosa. 



Melania gloriosa, Anthony, Amer. J. Conch., I, 1865, Pegu. 

 6 Saudoway District, Arakan ; ex c. Dr. F. Stoliczka. 



I have never seen as fine a specimen as that represented 

 in the Con. Indica, pi. 72, fig. 2 ["Bassein "] ; these Sandoway 

 ones are intermediate between the above-quoted figure and 

 fig. 6. Long. 66, diam. 30^ mil. 



var. peguensis [ ? dist. sp.]. 



Melania peguensis, [Anthony"], Hanley, Con. Indica, pi. 72, Jig. 6. 



2 Henzada, Pegu [typical of var.] ; ex c. Dr. F. Stoliczka [72; 26|]. 



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. 23| mil. ; decollate, of 5 whorls. 



This is the form nearest typical M. tourannensis, from which 

 it principally differs by not possessing the excavation below the 

 suture. It is a still smaller and more compact variety than var. 

 peguensis, with the spiral striae at base of last whorl very dis-
