ment is by the apex, the surface is sometimes transversely and 

 not longitudinally sculptured. 



Yar. CARPENTERI, Morch. 



Is founded upon the presence and form of the interior lamellae 

 as shown in section by the figure. Carpenter described it as 

 Petaloconchus renisectus (fig. 12). 



Y. VARIANS, d'Orb. PI. 49, figs. 22, 23 ; PI. 48, fig. 1 1. 



Irregularly convoluted, longitudinally rugoscly costate or 

 smooth, violaceous brown. 



Brazil to West Indies, W. coast of Florida. 



The varieties described by Morch need only to be named and 

 figured here ; the} 7 are scarcely of sufficient importance to justify 

 separate headings and descriptions. They are : 



Yar. CARPENTERI (fig. 11), West Indies ; var. OCCLUSA, Morch, 

 West Indies; var. MONILE, Morch, Honduras; var. IRREGU- 

 LARIS, d'Orb.; var. ELECTRINA, Morch; var. BADIA, Morch; 

 var. CANDIDISSIMA, Morch; var. PERLATA, Morch ; and var. 

 COSTATA, Morch ; all from the West Indies. As to var. 

 IRREGULARIS, Mo'rch quotes the text of d'Orbigny's Cuba, 

 but writes, " I am nearly sure that the group figured is a 

 SpiroglyphuSj perhaps mixed with a Vermetus." 



Y. CONICUS, Dillw. PL 49, fig. 24. 



Flexuose, spiral at base, tube rather thick, brownish white, the 

 spiral portion irregularly wound, about 8 whorls. 



West Indies. 



The sculpture varies as in the preceding species, it usually 

 consists of longitudinal striae ; the tube is much larger than in 

 V. varians, and also differs in its light color. It is V. lumbri- 

 calis,fl. of Gmelin. Morch has vars. PERSONATA, GORPIALIS (decus- 

 satus. Lam. non Gruel.), PROBOSCIS, RETIFERA. 



Y. RENISECTUS (Carp.), Morch. PL 49, figs. 25, 2G. 



Brownish ash-color, attached, spirally contorted, lightly longi- 

 tudinally lirate, the interstices rather smooth, especially towards 

 the aperture, incremental striae rugose, regular, somewhat gran- 

 ulated in intersecting the longitudinal lira 1 . Interior with two
