much more globose; it is extremely finely ribbed, and has 

 an almost spirally sinuous, very narrow aperture, with very 

 small and sharp varices on the columellar lip. Vitrcea is 

 still more globose, with a pellucid texture and coarser ribs, 

 angulated and depressed at the dorsal sulcus, which some of 

 them cross in continuation, while others end alternately with 

 each other. For brevissima, see sp. 168. 



169. subeosteata, Gray, (f. 480, 481, 482, et 489).— C. 

 testa, globosa, solida, fusco-purpurascenti ; margine dextro 

 obtuse marginato ; extremitatibus subrostratis, obtusis ; 

 sulco dorsali brevi, conspicuo ; costellis numerosissimis, per 

 sulcum pluriinis continuis, plurimis alternatim interrupts ; 

 basi rotunda ; columella brevi, utrinque obtuse varicosa ; 

 sulco subsequaliter angustato; apertura angusta, arcuata. 



170. pulla, Gash., (f. 490, 491).— C. testa C. subrostrata 

 affini, magis elongata, ; costellis tenuioribus, per lineam dor- 

 salem plerumque continuis, linea, dorsali subdepressa incon- 

 spicua ; sulco nullo. 



Note. — Subrostrata and pulla. The dorsal groove in subros- 

 trata is well-marked and conspicuous ; some of the ribs cross 

 it, others are interrupted and their ends intercalate. Pulla 

 has no distinct sulcus, has finer ribs, and is less globose.

 purpurascenti vel rosescenti, frequenter latera versus basim- 

 que nigricanti ; lateribus dilatatis, leviter depresso-margina- 

 tis ; extremitatibus obtusis ; linea dorsali brevi, vix depressa, 

 medio macula sanguinea magna, picta, utrinque albida ; cos- 

 tellis albidis, crassis, valide divaricatis et radiantibus, ple- 

 rumque per sulcum continuis ; basi convexa, labiis dilatatis ; 

 columella vix varicosa ; apertura arcuata, ad terminos leviter 

 arcuata, costellis dentalibus et interstitialibus crassis, albidis. 



172. posca, Gray, (f. 487, 488). — C. testa, 0. sanguinea 

 affini, parva, angusta, omnino fumeo-fusca ; costellis tenuio- 

 ribus ; dorso magis rotundo-elevato, linea, centrali albida ;

 acutis ; columella utrinque varicosa, labio angustato. 



173. edbinicolok, Gask., (f. 500, 501). — "C. testa ovato- 

 subglobosa, utrinque subrostrata, rubella ; extremitatibus
