10 SOLARIUM. 



siilcato and ril)l)ed above and below the })cripherv and near the 

 umbilicus; color as in S. per spectivum, exce\)t that the brown 

 band below the upper sulcus is usually wanting. 



Diam. 2'5 inches. 



Java ; Ceylon. 



S. Taylori, Hanley (PI. 3, figs. 33, 84), has somewhat coarser 

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

 agree with Reeve in th'nking it to be the same shell as *S'. 

 maxinium. 



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



Umbilical crenulations tinged with reddish-brown ; sculpture 

 and color as ,in S. Tayloyi. Diam. 2*5 inches. 



Zanzibar : Bay of Panama. 



This species is certainly very closel}' related to S. maxiniinn, 

 and is probably identical.

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

 near the umbilicus. Diam. 15 inches.

S. fragile, Hinds, is a sjnionym. This species is i)robably 

 identical with S. maximum. 



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

 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
