J 22 MR. K. A. SMITH ON LAND-SHELLS FROM [Feb. 5, 



L. tnliratus. The fourth lira surrounds the umbilicus, and the two 

 others are within it. The epidermis seems somewhat different, 

 and the peristome is a trifle less thickened than in the Labuan 

 species. These appear to be small differences ; still, thev will 

 probably prove to be constant in specimens from the two localities.

1 regret having overlooked GodN^in- Austen's L. mundyanus when 

 describing L. altvs. They are undoubtedly identical. A specimen 

 recently received differs from the typical form in being of a 

 uniform dark purplish-brown colour. 



69. Lagochilus qitadbicinctus. (Plate IV. fig. 10.) 



Testa parva, anguste umhilicata, turbhuita, tenuis, pellucido-albida, 

 ad apicem fuscescen^ ; nnfractus 5g, supremi 2-3 convexi, Iceves, 

 penidtimus convexiusculus, hicarinatus, ultimus mediocriter 

 convexus, carinis quatuor cinctus ; apertura fere cireularis ;

This species is somewhat like L. hantensis, Smith, but is much 

 smaller, without colour-markings, has larger nuclear whorls, and 

 is differently keeled. The peristome also is more widely expanded 

 and not so distinctly double.

 coll.) ; Natuna Islands (Smith). 



The intensity of the reddish colour is variable, and the outer 

 peristome is more remote from the inner in some specimens (e. g. 

 those from the Natuna Islands) than in others.

Testa dextrorsa, ovata, superne acuminata, cornea ; anfractus 6, 

 perconvexi, lameUis tenuissimis obliquis numerous omati.
