SOLARIUM. 1 5 



Tar. AUSTRALIS, Hanle}* (un figured). 



Tawny brown or reddish brown color, cither with spiral lines 

 of a darker color or banded above with small, close, white spots 

 and below with angulated white spots ; base and apical whorl 

 with spiral light and dark lines of color. 



S. CINGULUM, Kiener. PL 5, figs. 63, 64. 



Umbilicus contracted, crenulations white, very strong; whorls 

 regularly, spirally striated, ribbed at the periphery, spirally 

 sulcate and ribbed above and below the periphery and near the 

 umbilicus ; color white, upper part of the whorl 3-ellowish-brown 

 with rays of the same color descending to the periphery ; base 

 slightly convex and of a pale-smoky color. Diam. 1 inch. 



Sandwich Is.; Fiji Is.; Philippines. 



This species is easily distinguished by the scalloped white band 

 above the periphery. The shell differs from S. hybrid um in the 

 coloring and in the less convex base, but is probably only a 

 variety of that species. 



S. OXYTROPJS, A. Ad. PI. 5, figs. 65, 66. 



Shell depressed, umbilicus wide; whorls smooth, plane, ribbed 

 at the periphery, spirally sulcate and ribbed above the periphery 

 and near the umbilicus ; color white, glassy, ornamented with 

 yellowish brown ; base convex. Diam. 13 mill. 



New Caledonia. 



The type of this species which has been considered by Hanley 

 to be a young specimen of S. hybridum, differs from that form 

 in being quite depressed, in the widely open umbilicus, and in 

 the absence of a rib below the periphery. 



S. PSEUDOPERSPECTIVUM, Brocchi. PI. 5, figs. 67, 68. 



Shell very depressed ; umbilicus rather narrow ; whorls planu- 

 late above, having three nearly obsolete moniliform raised bands, 

 ribbed at the periphery, spiral^ sulcate and ribbed near the 

 umbilicus ; base slightly concave near the periphery, convex in 

 the middle. Diam. 1-4 inches. 



Mediterranean, Naples. 



S. perspectiviforme, Tiberi ; and S. discus, Phil., are synonyms. 



S. MEDITERRANEUM, Monts. PL 5, figs. 69, 70. 



Whorls 4-5, smooth, rapidly increasing, ribbed at the periph- 

 ery, spirally sulcate and ribbed above the periphery and near the
