hrouojht iu ballast from Lower California.

no. 298. 



299. Natica Souleyetiana, C. B. Ad., closely resembles N. maroccana, with larger 



umbilicus. 



300. Natica virginea, C. B. Ad.,+302, N, sp. ind. h,=Polinices uher, M. 576. 



301. Natica, sp. a, = maroccana, var. unifasciata. 

 318. ?? Truncatella dubiosa is probably a Paludinella. 



321. SuUa punctulata = B. Adamsii, M. 224.

325. Stomatella inflata is a Lamellaria. 



326. Hipponyx ?subrufa, 0. B. Ad., = S'. Grayanus, jun., M. 350, +?barhatus, jun. 



327. Hipponyx fbarbata, 0. B. Ad. The type-series contains If. harbatus, M. 349, 



-\-H. Grayanus + Discina Cumingii, M. 14 (valve). 



330. Caiyptrcsa aberrans is a valve of Anomia. 



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



tnamillarii, 

 333. Calyptma coniea. Most of the specimens are G. mamillaris, = 340, G. regu- 



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

 338. Calyptrcea planulata is a young flat C. cepacea. 



342. Calyptrcea fiunguis, C. B. Ad.,= Crucibulum spinosum, jun. 



343. Crepidula cerithicola= C. onyx, jun., M. 340, + C. incurva, jun., M. 339. 



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



to C. incurva. 



350. Crepidula unguiformis. Some of the specimens belong to this species ; others 



to C nivea. 

 S51. 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. 



352. Crepidula osculans belongs to another order, = Scutellina namceUaides, M. 269. 



353. Crepidula rostrata, 0. B. Ad., Rve.,= C. uncata, Mke., M. 338 ; and is perhaps

no. 359. 

 . 366, Siphonaria ?pica, C. B. Ad. Young dead limpets [?Acmeea']. 

 307. Lottia fpatina, C. B. Ad. [non Esch.], may stand, until more specimens have 



been collated, as Acmcsa (^fioccata, •vm.)Jilosa. 



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



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



vernicosa. 

 371. fPatella, sp. ind., resembles P. vulgata, but may be an Acmcsa. 

 372-376. There was no opportunity of dissecting the Amherst Chitons ; but among 

 the remaining duphcates of the collection (all of which were obtained and 

 brought to England) were the following : —
