 Hah. Summit of Mount Ambun, British North Borneo, at an 

 elevation of 3500 feet. 



This species \vas collected by Mr. S. B. J. Skertchly, who observes 

 on a ticket accompanying the two specimens, kindly presented to 

 the British Museum by Mr. J. J. Walker, "animal emerald-green, 

 so the shell looked green with white porcelain bands." 



Its small size and strong sculpture distinguish this species from 

 its allies, L. undatum, L. niaJiense, and L. r/eotrochiforme.

 Bah. Banguey Island, North Borneo. 



This species is clothed with a very hairy epidermis ; the hairs 

 are short, dark brown, situated upon the spiral lirae and the 

 impressed lines on the base of the body-whorl, and at the same 

 time they form oblique series in the direction of the lines of 

 growth. The epidermis is easily cleaned off, the shell then having 

 a very different look. The red radiating markings are curved and 

 somewhat wavy, but do not extend beyond the middle of the body- 

 whorl.
