148 39 12. Patella Mazatlandica, Mazatlan. This species did not occur among 

 the iBvriads of limpets lately sent from the same place. It closely 

 resembles AcnuBa cassis, Esch., and may really have come from the 

 North.

150 43 9. Chama echinata, Brod. Trans. Zool. Soc. vol. i. p. .306. pi. 39. f. 5-7. 

 The specimen figured iu these books, and in Chen. Conch. 111., as a 

 very old individual of Ch. echinata, is proved by the series in the 

 B.M. Mazatlan Coll. to be a comparatively young shell of Chama 

 frondosa, var. Mexicana. V. Cat. p. 87. no. 121. 



8. Venus neglecta. Central America, in saudy mud.

at Panama. The specimen here figured can hardly be distinguished 



from the young of C. proceruni. 

 152 42 3. Pectunculus inaqualis. Sow. Proc. Zool. Soc. 1832, p. 196. Sandy 



mud at Panama and Real Llejos. This is not the shell usually 



known by this name, and is accordingly quoted by Krauss for a
