Mangilia {?) incerta, sp. nov. (PI. IX., Fig. 1). 



Shell small, narrow, somewhat solid, fusiform, composed of five 

 and a half slightly convex whorls, with a well impressed suture. 

 Embryonic portion consists of a whorl and a half, smooth and 

 slightly swollen fi'om the dorsal aspect, and apparently with an 

 exsert tip. 



The penultimate and spire whorls relatively strongly ornate, 

 with close narrow costae traversed by a few strong spiral threads ; 

 on the penultimate whorl itself there are twelve or thirteen costae 

 which are broader than the interspaces, and there are about five 

 spiral threads, the median one being the coarsest. 



The costae gradually fade out on the body whorl, but there 

 are numerous (about fifteen) more or less irregular spiral threads, 

 the strongest being situated at about the shoulder. 



Aperture elongate-ovate, a little less than half the length of 

 the shell, with a very broad anterior canal ; columella smooth, 

 slightly excavated medially, and with a gentle twist towards the 

 anterior end.
