DirLomMatina, Benson. 
41. DipLomMaTINA ConcinnaA, H. Adams. 
Diplommatina concinna, H. Adams, P. Z. 8. 1872, p. 13, pl. iii. 
fig. 22. 
This figure, though small, is, from the very peculiar and distinct 
form of the shell, sutticient for i ita identification, and I have therefore 
not given an enlarged drawing. 
42. DipLOMMATINA RUBICUNDA, v. Martens. 
Pawxillus rubicundus, v. Martens, Monatsber. d. Berlin. Akad. 
1864, p. 119; Preuss. Exp. Ost-Asien, Die Landschnecken, p. 164, 
pl. iv. fig. 17 (1867). 
Hao. Benkajang and Singkawang. 
43. DipLommatina apversa, H. & A. Ad. (Plate XX XVIII. 
. 3.) 
Paxillus adversus, H. & A. Adams, Ann. & Mag. Nat. Hist. 
ser. 2, vii. p. 63 (1851). 
No figure having ever been given of this species, I now give one 
from a specimen received from Mr. Henry Adams some years ago 
and in my collection.

Pazillus beecarii, Issel, Moll. Born. Ann. Mus. Civ. Genova, vi.

45. DirLomMMaTINA ISSELI, n. sp. (Plate XXXVIII. figs. 
5, 9a.) 
Shell sinistral, elongately fusiform, slightly rimate; sculpture 
very fine spiral liration, crossed by well-defined regular somewhat 
close costulation ; colour sienna-brown ; spire high, tapering rapidly ; 
apex fine; suture well impressed ; Sion 8 8, Saba convex, the last 
the largest, not ascending, constriction (fig. 5a) on side $ a whorl 
behind aperture, where position of operculum may be seen ; aperture 
very oblique, oval; peristome double, not thickened, reflected 
slightly, with a thin callous on the last whorl; columellar margin 
with a blunt rounded tooth. 
Size: maj. diam. 2°9 ; alt. axis 4:0 millim. 
Hab, Sarawak proper and Busan Hills (A. Everett). 
The species occurred also among the shells trom the cave 
deposits. 
‘This is a very peculiar form, and much more worthy of subgeneric 
distinction than Paazlus, which is only a reversed Diplommatina. 
46, DipLOMMATINA BUSANENSIS, n. sp. (Plate XXXVII. fig. 4.) 
Shell sinistral, ovately fusiform, somewhat short; sculpture fine 
longitudinal striation, crossed by distant regular well-marked constula- 
tion; colour orange-brown, dark madder-brown on apex; spire 
turreted ; apex pointed ; suture deep ; whorls 6, sides very convex,
