SOLARiELLA (SOLARICIDA) KONDOENSIS, new species. 



Shell of moderate size with six moderately inflated whorls, the 

 nucleus lost, the color olivaceous, the suture distinct, not appressed; 

 spiral sculpture of (on the upper whorls two, on the last two whorls three) 

 sharp threads behind the periphery raised into rather sharp nodules 

 at the intersections with the axial threads, and with wide interspaces 

 between the suture, each other and the following tlireads, the first 

 of which on which the suture is laid and three similar threads on the 

 base are minutely beaded, while the last, at the verge of the funnel 

 shaped axially striated deep umbilicus is m.ore coarsely beaded; 

 axial sculpture of fine sharp threads more or less obsolete in the inter- 

 spaces but forming nodules at the intersections and between them 

 finer sharp close threadlets; not nodulating the posterior spirals; 

 base convex, aperture rounded, the pillar and outer lip continuous 

 thin and sharp, the inner lip erased, pearly; operculum thin, multi-

SOLARIELLA DIOMEDEA, new species. 



Shell small, white with pinkish brown touches on the prominences 

 and four or five brown radial flecks on the spire; whorls five exclusive 

 of the glassy subglobular nucleus, flattened in front of the suture, 

 otherwise well rounded; spiral sculpture on and near the periphery of 

 five or six subequal cords with narrower interspaces; on the base are 

 about eight finer closer threads extending to the verge of the funic- 

 ular umbilicus within which are four stoutly beaded strong cords 

 diminishing in strength inward; axial sculpture of numerous fine equal 

 regularly spaced threads with wider interspaces, beading the posterior 

 spiral and conspicuous on the flattish part of the whorl; aperture 

 circular, hardly interrupted at the body, the margin thin, crenulated 

 by the sculpture; operculum multispiral, concave, translucent; height 

 of shell, 4 ; diameter, 5 mm. U. S. Nat. Mus. Cat. No. 194971.
