The species is new for the E. Indian-Archipelago, at least Pilsbry mentions only China 

 as the habitat. It is a much smaller species than the preceding one, the type may be at once 

 distinguished by the beautiful rose-colour.

This shell agrees exactly in sculpture with E. rtiber and with specimens of var. brunneus 

 received from Japan, it is still smaller than Pilsbry's specimens, being only 5 1 /, Mill. in altitude 

 instead of 6 1 /.,. In colour it differs little from many specimens of the preceding species. The 

 interstices of the spiral lirae are narrow, as well in the type as in the variety. I can detect no 

 intermediate lirae, nearly always very distinct in E. atratus, only faint traces of them may be 

 eventually found, when the interstices are slightly broader.

This species is also new to the fauna, its habitat, mentioned by Pilsbry, being Viti-islands, 

 New Caledonia, and with doubt also Japan. In his "Catalogue of the Marine Mollusks of Japan, 

 collected by F. Stearns", published in 1895, Pilsbry does not mention it. 



4. Euchelus ringens n. sp. PI. VI, fig. 6. 



Stat. 98. 6°9'N., i2o°2i'E. 350 M. Sand. 1 Spec. 



Shell globose-conical, probably imperforate, rather thin, flesh-coloured, with 3 rows of dark 

 brown spots on the upper whorls, nucleus white, lower 2 l / 2 whorls with faint brown blotches 

 near the upper part and scattered brown dots. Sutures deep, canaliculate, whorls 5, com-ex. 

 Nucleus smooth; upper whorls with from 2 to 3, penultimate one with 5, last with 14 spiral 

 lirae, and a few intermediate ones, becoming more numerous towards the aperture, the principal 

 lirae are conspicuously beaded, the intermediate ones less so, the interstices are crossed by 

 lamellae, often corresponding to the beads. Body whorl slightly depressed but not angular. 

 Aperture rounded, very oblique, margin slightly expanded, with a broad, flat rib interiorly, with 

 numerous elongrate wrinkles and a few shorter intermediate ones at the outer margin: margrins 

 connected by a thin expanded callosity with regular wrinkles, the whole circumference of the
