124 MR. E. A. SMITH ON LAND-SHELLS FROM [Feb. 5, 



The Palawan specimens have half a whorl less than those from 

 Luzon, the spire above the penultimate volution appearing in 

 consequence a trifle shorter. The sculpture, form of aperture, 

 and columellar denticle are the same '.

Hab. Busau (ty^ic) ; Mulu Mountain and Mount Eabong, 

 Sarawak ; also Balabac and Palawan (A. Everett). 



This species is rather variable in size, even among specimens 

 from the same locahty. Some examples are stouter than others, 

 and one from the cave-earth, in a semi-fossilized condition, has an 

 exceptionallv tall spu*e. There is A^ery little variation in the form 

 of the aperture, the peristome, and sinuses.

 spira depressa, ajnceobtuso, prominido ; anfractus 5, convexi, 

 celeriter nccrescentes, sutura jjrofunda sejimcti, idtimus antice 

 leviter descendcns ; apjertura mediocris ; peristoma duplex, 

 marr/ine e.rterno superne laio, teinii, liavd reflexo,prope suturam

 inter carinas acutas excavaium, sordide cdbidum, ex anfractibus

Var. PABVA. Testa minor, concolor, vel supra plus minus maculata ; 



peristoma angustius expansum. Diam. maj. 15g millim, 

 Hab. Maranggas, S.W. Palawan. 



If very carefully examined, a very faint peripheral zone is 

 traceable.

Hab. Luzon and Negros, Philippines {Sau'erby) ; Marinduque 

 and Cebu {Hidalgo) ; Palawan {Everett). 



Two specimens from Palawan, 9 millim. in diameter, are peculiar 

 in having the last half of the body-whorl disconnected -with the 

 penultimate. 



' In my Eeport upon the Land-Shells of the Natuna Islands, I named a 

 species belonging to this genus D. strubeUi. I regret to find that that name 

 had already been used, and propose therefore to change it to D. brunonis.
