ZONITES. 



135 



from Taygetos, and Bottger has described, without figure, a var. 

 Narentana. 



Z. cultellatus, Thomson (fig. 79), was found living, plentifully 

 in Contra Costa Co., California, nearly thirty years ago, by Mr. 

 John H. Thomson, of New Bedford, Mass. It has not occurred 

 since to California]] collectors, and was doubtless the progeny 

 of an importation, which finally succumbed. I think it may 

 safely be referred to this species. 



Z. COMPRESSUS, Ziegler. PI. 44, figs. 73, 14. 



Widely umbilicated, much depressed, periphery obtusely angu- 

 lated, ver}' minutely clathrate and light brownish above, smooth, 

 shining and yellowish or yellowish white below, periphery nar- 

 rowly white banded. Diam. 32 mill. 



ML Tersatto, near Fiume. 



It is H. morlachica, Parr. Var. lardea, Stentz (unfigured), is a 

 little larger, the spire a little higher, the periphery more obtusely 

 angulated ; var. Italica, Kobelt (fig. 74), is from Mt. Majella. 



Z. ACIES, Partsch. PL 44, figs. 75, 76. 



Widely umbilicated, convexly lenticular, periphery distinctly 

 carinated, rugosely striated and very lightly decussated above, 

 reddish corneous, carina whitish, below yellowish white, smooth 

 and shining. Diam. 31 mill. 



Dalmatia. 



The s} T nonyms are H. acumen, Fer. ; H. acutimargo, Ziegl., 

 and H. algira, Olivi ? 



Z. CRYPTA, Parreyss. PI. 45, figs. 77, 78. 



Differs from the preceding species in the growth-striae being 

 finer and less rugose, and in having much more distinct close 

 spiral lines. Diam. 26 mill. 



Caverns in Dalmatia. 

 Z. CARIOUS, Roth. PL 45, figs. 80-82. 



Umbilicated ; rather solid ; whorls 4j, obliquely rugate and 

 closely granulated above, yellowish corneous, the vertex shining, 

 subimmersed, periphery subcarinated, below smooth, scarcely 

 lighter colored. Diam. 25 mill. 



Asia Minor. 



Differs from the preceding species most strikingly in having 

 fewer whorls.
