330. Calyptrcea aberrans is a valve of Anomia. 



331. Calyptraa aspersa= Galerus conicus, broken, worn, and young; one sp. may be 



mamillaris. 

 333. Calyptrcea conica. Most of the specimens are G. mamillaris, = 340, G. reyn- 



laris ; but a few may be the true G. conicus, worn, M. 332.

349. Crepidula squama. Some of the young shells belong to C. onyx ; one perhaps 



to C. incurva.

to C. nivea. 



351. Crepidula nivea. The type-specimens are small, poor, and rough, of the var. 



striolata, passing into Lessonii. Perhaps, therefore, the first name squama 

 should be retained for the species (nos. 348, 349, 350, part, and 351), leaving 

 striolata and Lessonii for the vars.

 no. 359. 



366. Siphonaria ?pica, C. B. Ad. Young dead limpets [?Acmcea~\. 



367. Lottia ?patina, C. B. Ad. [non Esch.], may stand, until more specimens have

368. Lottia, sp. ind. a, may be quoted as Acmcea (?floccata, var.) subrotundata. 



369. Lottia, sp. ind. b, may rank, for the present, as Acmcea (?vespertina, var.) 



vernicosa. 



371. ? Patella, sp. ind., resembles P. vulgata, but may be an Acmcea.
