248 MELANIID^J. 



Long. 28, diam. 10| mil. ; anfr. 6J. 

 Not unlike Troschel's Mel. adspersa. 



var. minor [? M. tuberculata, var.]. 

 10 Mahe, Seychelles; coll. G. Nevill, Esq. 



A small, strongly decollate form, without longitudinal sculp- 

 ture ; appears to me fairly intermediate between the small, 

 truncated Mauritian variety of M. tuberculata and typical 

 M. commersoni. 



Sub-Genus MELANOIDES, H. & A. Adams. 



Gen. Moll. I, page 296, 1854, type [ as figured} Mel. asperata, Lam., as 

 Genus Melanioides, Olivier. 



I am unable to accept this section as of Olivier, in which case 

 the type could evidently only be Mel. tuberculata, Mull. [=fas- 

 ciolata, Oliv.'] ; I cannot find the word "Melanioides" in Olivier ; 

 and Ferussac in his Tabl. syst. merely mentions a *' Melanoide, 

 Olivier." Messrs. Adams included Mel. tuberculata in this 

 subgenus, but M. Brot rightly, as I consider, separates it. 



37. Melania [Melanoides] reevei. 



Melania reevei, Brot, Mater. 1, 1862,; =M. lalteata, Rv.[not Philippi] = 

 M. goliath, Hanley, Con. Indica, pi. 72, Jig. 3 ; var. =M. herculaa, 

 var., Srot, Mat. II, pi. 3, fig. 3 ; fide Hanley [not Bro]juv. ? =M, 

 Tiumerosa, Gld., P. Bost. S. 1840, "ManJco, Tavoy," long. 1%, diam. \poll. 



5 Pegu ; ex c. Dr. F. Stoliczka. 



Agree exactly with Con. Indica, pi. 72, fig. 3. Anfr. 4 ; long. 

 66|, diam. 32f mil. 



3 Myadoung; coll. Dr. J. Anderson [39, 16$]. 



Apparently not quite adult ; perhaps will prove a distinct, new 

 variety. 



var. lanceolata, nov. 



Con, Indica, pi. 153, fig. 1, Burma. 



M. Brot considers this the young state ; I am inclined to think 

 it an adult and very constant form.
