Nearly related to G. grceca of the Mediterranean, but attaining 

 much larger size, the latticed sculpture generally coarser, the apex 

 more central, bounded by a black line, as it usually is in the grceca. 

 The two forms are very closely allied, separated more on account of 

 their different distribution than for any other reason. F. nigro- 

 ocellata Rve. should be compared with the young of this species. 

 See under G. sieboldii Rve. 



G. fontainiana Orbigny. PI. 62, figs. 28, 29, 30. 



Shell ovate-oblong, subconic, narrower in front, white, longitudi- 

 nally and transversely ribbed, decussated, the ribs acute, unequal ; 

 fissure subrotund, large. Length 20, alt. 8 mill. This charming 

 species approaches the F. grceca, but it is more elevated, more conic, 

 the hole rounder, wide and horizontal ; the ribs are more elevated 

 and salient, spinose ; the internal hole-callus is narrow and equal 

 all around, not truncated behind. (Orb.)

G. foveolata Garrett. PI. 03, figs. 17, 18, 19. 



Shell oval, conical, hole a little in front of the middle, slopes 

 .straight or convex posteriorly. Surface having about 18 strong 

 radiating ribs (with some smaller interstitial riblets usually) crossed 

 by raised concentric threads, which bead the ribs and cut the inter- 

 stices into deep squarish pits. 



White or brownish, with irregularly scattered spots of black or 

 deep brown, the spots showing through the thin shell on the inside. 

 Hole-callus truncated behind. Length 8'., width 6, alt. 3 ] mill.

Very coarsely sculptured, like a small G. grceca or G. listeri. 

 The hole-callus is dark. The largest specimen was unfortunately 

 broken, so that the figures and measurements are from a smaller 

 one. I do not know where it was originally described. The speci- 

 mens are from Garrett. 



G. granifera Pease. PI. 03, fig. 13. 



Shell small, oval, conical, elevated, the apex a little in front of 

 the middle; slopes straight or nearly so; sculptured with subequal
