SPECIES OF LAND-SHELLS FROM BORNEO. 345 



liris tenuissimis paucis (in anfr. superioribus 3, ultimo 4) spiraliter cincti, 

 lineis increraenti exilissimis striati, ultimus ad peripheriam acute rotun- 

 datus, inferae striis spiralibus pamtn distinctis sculptus, antice vix des- 

 cendens ; apertura intus albida, circularis ; peristoma leviter incrassatum, 

 duplex, superne vix expansum, inferae et prope umbilieum angustissime 

 reflexura. 



Diam. maj. 11 millim., min. 8; alt. 8|. Apertura 5 longa et lata. 



Sab. N.E. Borneo. 



The wliite radiating markings whicli ornament the upper surface 

 of this pretty species stop short at the periphery, leaving the 

 base of a uniform, chestnut tint. The notch in the peristome is 

 slight, but quite evideut at the point where the upper margin 

 meets the vrhorl. Of the four thread-like lirae upon the body- 

 whorl, the three uppermost revolve up the spire, and the fourth, 

 which is just below the periphery, passes into the suture and is 

 not seen upon the upper whorls. 



8. Lagocheilus inornatus. (PI. XXV. fig, 8.) 



Testa depresse turbinata, mediocriter umbilicata, albida, pellucida, ad 

 peripheriam carina filiforme cincta, striis incrementi tenuibus sculpta; 

 spira breviter eonica ; anfractus 5-6, convexi, inferne prope suturam carina 

 vel lira spirali instructi, ultimus circa umbilieum lira alia ornatus, ad 

 carinam medianam epidermide pilosa amictus, antice vix descendens ; aper- 

 tura circularis ; peristoma duplex, margine externo mediocriter expanso, 

 subreflexo. 



Diam. maj. 8| millim., min, 7; alt. 7. Apertura 3| longa et lata, 



Sah. Gromanton, N. Borneo. 



This species is peculiar in the absence of markings and on 

 account of the peripherial and basal lirse. 



9. Lagocheilus alius. (PI, XXV. fig. 9.) 



Testa parva, elato-conica, anguste perforata, subpellucida, pallida, 

 epidermide tenuissima pilosa induta, strigis obliquis rufescentibus ornata ; 

 anfractus 5|, convexi, liris tenuibus pilosis (in anfr. superioribus 2, in ultimo 

 5) incrementique lineis obliquis tenuibus subdistantibus late cancellati, 

 ultimus rotundatus, baud descendens ; apertura circularis ; peristoma intus 

 leviter incrassatum, album, extra anguste expansum, rufescens, ad parietera 

 tenuissimum. 



Diam. maj. 4 millim., min. 3 ; alt. 4|. Apertura 2 longa et lata. 



Sab. Busau, N.W. Borneo. 



The apical whorls are reddish, but this may be partly due to 

 the remains of the animal. The spiral elevated lines are a 

 trifle coarser than the rather distant oblique ones, and it is at 

 the points of intersection that the short epidermal hairs arise.
