40 CYPR/EA. 



A***. Ribbed, or tuberoulated, or allied to those that are so ; 

 columella)' plait distinct. 



136. Adamsoni, Gray, (f. 401, 402). — C. testa parva, pyri- 

 formi, cancellata, fulva, maculis aurantiis polygonis 6 ad 7 

 ad dorsum picta; extremitatibus productis, labii superne 

 elevata acuminata incurva, sulco columellari angusto, plica 

 terminali parva distincta. 



Note. — This beautiful little species is not striated or 

 ribbed in the same manner as the Trivice, with which it has, 

 indeed, little affinity. The ribs are spiral, and the terminal 

 columellar plait and lobe are distinct. 



137. pustulata, Lamk., (f. 396, 397; set. juv. 398).— C. 

 testa ovata, fusco-cinerea, ad dorsum pustulis aurantiis ro- 

 tundis rubro-marginatis ornata ; extremitatibus productis, 

 approximatis ; basi distanter albicostata, planata, cicatrice 

 dorsali angusta. 



Note. — In the young state, the shell is spirally ribbed as 

 in 0. Adamsoni. The pustules only appear in adult shells. 



138. staphylsa, Linn., (f. 223-229 et 518).— C. testa ovato- 

 oblonga, subdepressa, crassiuscula ; dorso plerumque granu- 

 loso, interdum lsevigato, granulis vel maculis rotundis albis ; 

 extremitatibus aurantio-fusco tinctis, productis, acutis sive 

 obtusis, marginibus reflexis, foveolatis ; basi subcomplanata ; 

 dentibus super basim omnino vel partim prolongatis. 



Var. laevigata, pallida, tenuis, acuta; dentibus tenuibus, 

 f. 225, 225 ; fimbriatula, f. 518. 



Note. — No species is so widely variable as this. In f. 228, 

 229, it is a rounded, beaked shell, granulated all over at the 

 back, and with the dental ridges completely crossing the 

 base. In f. 223, 224, and 227, the interstincta of Wood, and 

 the limacina of Lamarck, the middle teeth of the columellar 

 lip stop suddenly before reaching halfway over. The pale, 

 thin, sharp variety is from the Sandwich Islands. All these 

 varieties, differing extremely in some specimens, yet pass 

 imperceptibly into each other, so that it is impossible to 

 separate them. 



139. nucleus, Linn., (f. 399, 400). — C. testa alba, seu fulvo- 

 rubescenti, ovata; extremitatibus productis; dorso elevato, 

 irregulariter tuberculato, tuberculis intercostatis ; basi sub- 

 rotunda, costellis transversis numerosis, ad marginem inter- 

 mediis divergentibus, terminalibus distinctis divaricatis ; 

 apertura angusta, cicatrice dorsali latiuscula.
