narrow, rounded ribs, about 12 in number on last whorl, crossed by thin Iirae in upper part 

 of whorls and in the basal part of last whorl; the Iower part of upper whorls and median 

 part of last one being impressedly striate. These lirae in crossing the ribs, make thcm nodulous 

 to nearly spinose, slightly crenulate on lower part, and again granose on the base of last whorl 

 else the interspaces of the ribs are smooth, but for fine growth-striae. Aperture oblong-oval, 

 rather bluntly angular above; peristome not thick, though thickened exteriorly, a little backwards, 

 by a stronger rib, lirate internally, at some distance from the peristome, by about 15 lirae; 

 columellar margin rounded, smooth, with a conspicuous, oblique basal fold and tracis of a 

 second one, a little higher on. Canal shallow, wide, slightly directed to the left. 



Alt. [O, lat. 4 s / 4 ; apert. alt. (with canal) 5, lat. 2 Mill. 



This small species is very different from any species I know, but its generic characters 

 agree with those of the known species of Phos\ unfortunately the dredging consists of more 

 or less fresh shells, without the soft parts; the specimens vary in the development of the spiral 

 lirae as mentioned above, but in other respects they have all the same specific character.

Reeve did not know the habitat of this species. Smitii recorded it from the Andaman 

 isles, v. Martens from Mauritius, Hidalgo from Cebu, the locality of the Siboga-specimen is 

 in accordance herewith.

The only specimen from Stat. 240, which is in good condition, agrees as much as can 

 be desired with somewhat worn specimens from Lifu ; that from Stat. 33 is not aclult, at least 

 the peristome is still thin, it is larger (13 1 /., Mill.), the central white band is less developed, it 

 seems to be notwithstanding these difterences, only a somewhat larger form of E. sinensis.
