10 SOLARIUM. 



sulcate and ribbed above and below the periphery and near the 

 umbilicus; color as in S. perspectivum, except that the brown 

 band below the upper silicas is usualh' wanting. 



Diam. 2'5 inches. 



Java ; Ceylon. 



S. Taylori, Hanley (PI. 3, figs. 33, 34), has somewhat coarser 

 sculpture and a double band of color below the suture, but I 

 agree with Reeve in tlrnking it to be the same shell as S. 

 maximum. 



S. QUADRICEPS, Hinds. PI. 4, figs. 39, 40. 



Umbilical crenulations tinged with reddish-brown ; sculpture 

 and color as in S. Taylori. Diam. 2*5 inches. 



Zanzibar ; Bay of Panama. 



This species is certainly very closely related to S. maximum, 

 and is probably identical. 



S. PICTUM, Phil. PL 3, figs. 35, 36. 



Umbilical crenulations white ; sculpture as in S. maximum ; 

 color purple-fawn, with two interrupted bands of reddish-chestnut 

 below the suture, the ribs at the periphery spotted with reddish- 

 chestnut ; base with a band of distant, round reddish-brown spots 

 near the umbilicus. Diam. 1-5 inches. 



New Guinea. 



S. fragile, Hinds, is a synonym. This species is probably 

 identical with S. maximum. 



S. TRYONI, Marshall. PI. 2, figs. 28, 29. 



Umbilical crenulations white; whorls spirally bisulcatc below 

 the suture, ribbed at the periphery, spirally sulcate and ribbed 

 above the periphery and near the umbilicus, ribs crenulated ; sur- 

 face of the shell covered with radiating, almost direct, impressed 

 growth-lines ; color light purplish chocolate, with an interrupted 

 chestnut band on the space between the suture and the upper 

 sulcus, another very narrow band just below the upper sulcus, 

 none of the spots reaching to the second sulcus, a band reaching 

 from the periphery beyond the rib above it and changing from 

 orange-3 r ellow on the periphery to chestnut above; base with the 

 rib of the periphery elevated and an interrupted band of orange- 

 brown near the umbilicus. Diam. 1 inch.
