ART. 18 SMALL SHELLS DREDGED BY " ALBATROSS " DALL 129 



one on each side of the periphery, and three less prominent on the 

 base, tlie inner one forming the margin of the funicular umbilicus; 

 axial sculpture of sharp radiating lamellae, nodulose on the presutu- 

 ral ridge, with much wider interspaces, only slightly enlarged where 

 they cross the spiral cords, beading the verge of the deep umbilicus 

 into which they prominently descend; base rounded under the sculp- 

 ture, aperture rounded except for the modification by the spiral sculp- 

 ture, thin sharp-edged, somewhat oblique. Height of shell, 4; of last 

 whorl, 3; major diameter, 5 mm. U. S. Nat. Mus. Cat. No. 1G8424. 

 Thirteen specimens and fragments off Georgia, and 19 young shells 

 off Fernandina. A fragment has a major diameter of 6 millimeters, 

 but the description is based on a younger and more perfect specimen. 



SOLARIELLA ANOXIA, new species 



Shell small, white, with about five whorls following an obliquely 

 tilted glassy subglobular nucleus; the cone of the shell is acute, except 

 that the last whorl suddenly disproportionately enlarges; suture dis- 

 tinct, a small flattening in front of it gives a slight effect of tabulation 

 to the whorls; spiral sculpture of (on the spire two, on the last whorl 

 above the base, five) rather angular ridges, on the last whorl one near 

 the suture, and four a little nearer the periphery, alternating in prom- 

 inence, with subequal interspaces, and on the rounded base with 

 much wider interspaces; there is no sharp edge to the moderate-sized 

 funicular umbilicus; axial sculpture of numerous low equal and 

 equally spaced vertical lamellae which extend over the whole surface 

 minutely nodulating the intersections with the spiral sculpture, form- 

 ing a neat reticulation; aperture rounded, the lips thin, united over 

 the body by a thin wash of enamel. A vai'iety occurs with the spi- 

 rals feeble or partly obsolete. Height of shell, 3; of last whorl, L7; 

 major diameter, 2.5 mm. U. S. Nat. Mus. Cat. No. of type, 108142; 

 of the variety, 108420. 



Ten specimens, mostly young, off Fernandina, nine off Georgia. 



SOLARIELLA TUBULA, new species 



Shell small, white, depressed conical, with four well-rounded whorls 

 following a glassy subglobular nucleus; suture distinct, not deep; 

 spiral sculpture of a few feeble striations in front of the suture, the 

 peripherj^ mostly smooth, and two or three threads around the verge 

 of the wide funicular umbilicus; axial sculpture, most distinct on the 

 younger whorls, of numerous equal and equally spaced radiating 

 wrinkles, most prominent on the shoulder of the whorl, barely reach- 

 ing the periphery, and frequently obsolete on the last whorl; there is 

 sometimes a low ridge near and in front of the suture, giving an exca- 

 vated look to the depression between them, and in crossing this ridge 

 the wrinkles become feebly nodulous at the intersections. Height of 

 shell, 3; major diameter, 5 mm. IT. S. Nat. Mus. Cat. No. 108140.
