adly pyramidal, with short canal, yellowish-white, stained with brown and with 



white streaks. Whorls 9, ol which about 2 form a smooth, convexlj whorled, 



i nucleus. Subsequent whorls slightly contracted above, not verj convex below, 



. bj .1 conspicuous, slightly waved suture; sculpture consisting in the excavation of a 



ig liration, single in upper whorls, divided lower <>n by a groove, and correspondinglj adorned 



or doublé row of beads, below this, 2 narrow lirae run still in the excavation; lower 



part i>f whorls with a larger number of lirae, 6 in penultimate whorl, about 25 in last whorl, 



inclusive of canal, with more or less conspicuous intermediate ones in many interstices. These 



lirae are crossed 1>\ oblique, on lower whorls by waved ribs, more conspicuous and remote on 



upper whorls, closer and fainter on last one, producing beads where they are intercrossing, 



the last whorl having the appearance of being more or less regularly bcaded all over. The 



brown colour is very irregularly divided, on the infrasutural hand it is nearly continuous but 



on the body-whorl darker brown beads alternate with lighter or even white ones. Last whorl 



rather convex, attenuated below, ending in a short, rather broad canal. Aperture oval, with a 



wide sinus above, peristonie thin, regularly arcuate, columellar margin concave, running in the 



canal, which is wide and slightly directed to the left ; interior of aperture bluish white, coluni- 



ella with a thin layer of white enamel.

I know nu species which is nearly allied to this one, in sculpture it resembles somewhat 

 D. digitalis Reeve, but not at all in shape or colour.

The Siboga-specimen is larger than Weinkauff's one, (38 instead of 31 MUI. in Iength . 

 but otherwise it agrees as well as can be desired, with his description and figure; Weinkauff did 

 not know its locality. Tryon says (1. c.) it is an immature D. umbilicata Gray, the quoted 

 localities are "Sierra Leone (Gray); West-Indies (Swift)"; the Siboga-specimen has not at all a 

 juvenile app e and this circumstance, connecteil with the remote locality, may plead for my 



opinion that the two species may stand. As I have seen no other specimens, I cannot insist 

 on the other important differences in shape and particulars of aperture, between the existing figures.
