This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1835 edition. Excerpt: ...fusco-violaced. Diam.-f-poll., lat. Hab. ad Sanctam Elenam. The back of this shell is not unlike the upper valve of some of the TerebratuUe. Found on dead shells in sandy mud, at a depth of six fathoms. 21. CALYPTRjEA DILATATA, Lam. Varietas intus nigro-castanea. Tab. XXVIII. Fig. 11. Cal. testd sordide albd castaneo strigatd, intus nitide nigro-castaned, lamind albd. Diam. If poll., lat. If, alt. f. Hab. ad Valparaiso. This highly coloured variety was found on exposed rocks at low water. The pure white of the plate shows to great advantage, lying above the rich back ground of the interior of the shell. In some individuals this internal colour is all but black. 22. CALYPTRjEA STRIGATA. Tab. XXVIII. Fig. 12.

Cal. testd albidd violaceo maculatd, interdum fuscd, striis longitudinalibus creberrimis, spinis fornicatis horridd, intus Jlavente vel albd. Diam. 1] poll., lat. If, alt f. Hab. ad Peruviam. (Lobos Island.) In old specimens the spines are almost entirely worn down, and rough stria only for the most part remain. In this state it bears a great resemblance to the figure given of Crepidula fornicata in Mr. Sowerby's ' Genera of Shells', No. 23. f.. Found under stones at low water. 24. CALYPTRjEA Hystrix. Tab. XXIX. Fig. 2. Cal....
