ON MOLLUSCA OF THE WEST COAST OF NORTH AMERICA. 551 
striulata, M. 2836. Its operculum proves it to be a true Phasianella, and 
not Melaraphe phasianella, Phil., of Add. Gen. 
Turbo rutilus, the worn remains of what perhaps was once Pomaulax undosus, 
brought in ballast from Lower California. 
Sealaria, oe ¢, = Opalia funiculata, jun., M. 569, 
Eulima ( Leiostraca] iota appears distinct from Z. retexta, M. 555, 
Eulima | Mucronalia) solitaria=Letostraca, sp. a, M, 552. 
Pyramidella, sp.,= Obeliscus Adamsii, M. 486. 
Natica hurida, C, B, Ad.,=pale var. of N. maroccana. 
Natica otis, C. B, Ad. (non Br. and Sby.), = Polinices “ Salangonensis,” C. B. Ad., 
no. 298, 
Natica Souleyetiana, C. B. Ad., closely resembles WV. maroccana, with larger 
umbilicus. 
Natica virginea, C. B, Ad.,+302, N., sp. ind. b,= Polinices uber, M. 576, 
Natica, sp. a, =maroccana, var. unifaserata. 
?? Truncatella dubiosa is probably a Paludinella. 
Bulla punctulata=B. Adams, M. 224. 
Bulla, sp.=Tornatina carinata, M. 225. 
Vermetus Pglomeratus, C. B. Ad.,=V. eburneus, Rve., M. 354. 
Vermetus Panamensis, C. B. Ad.,= Aletes centiquadrus, M, 352. 
Stomatella inflata is a Lamellaria. 
Hipponyx Psubrufa, C. B. Ad.,=H. Grayanus, yun., M. 550,+Pbarbatus, jun, 
Hipponyzx Pbarbata, C. B, Ad. The type-series contains H. barbatus, M. 549, 
+H. Grayanus+ Discina Cumingii, M. 14 (valve). 
Calyptrea aberrans is a valve of Anomia. 
Calyptrea aspersa= Galerus conicus, broken, worn, and young; one sp. may be 
mamillaris. 
Calyptrea conica. Most of the specimens are G. mamillaris,=340, G. regu- 
laris; but a few may be the true G. conicus, worn, M. 332. 
Calyptrea planulata is a young flat C. cepacea. 
Calyptrea ?Punguis, C. B. Ad.,= Crucibulum spinosum, yun. 
Crepidula cerithicola= C. onyx, jun., M. 340,+ C. ineurva, jun., M. 339. 
Crepidula squama. Some of the young shells belong to C. onyx ; one perhaps 
to C. incurva. 
Crepidula unguiformis. Some of the specimens belong to this species ; others 
to C. nivea. 
Crepidula nivea. The type-specimens are small, poor, and rough, of the var. 
striolata, passing into Lessonii. Perhaps, therefore, the first name sqguama 
should be retained for the species (nos. 348, 349, 350, part, and 351), leaving 
striolata and Lessoni for the vars. 
Crepidula osculans belongs to another order, = Seutellina navicelloides, M. 269. 
Crepidula rostrata, C. B, Ad., Rve.,=C. uncata, Mke., M. 338; and is perhaps 
distinct from C. adunca, Sby.,=solida, Wds.,=rostriformis, Gld. 
Fissurella microtrema. Dead shells, of which part= V. rugosa, var. M. 273. 
Fissurella mus. Intermediate between Gilyphis inequalis, M. 279, and yar, 
ica. : 
Biaurlla virescens. Intermediate between F. v., M. 271, and F. nigropunctata, 
no. 359. 
Siphonaria ?pica, C. B. Ad. Young dead limpets [? demea}. 
Lottia ?patina, C. B. Ad. [non Esch.}, may stand, until more specimens have 
been collated, as demea (2floccata, var.) filosa. _ 
Lottia, sp. ind. a, may be quoted as Acmea (?floccata, var.) subrotundata. 
Lottia, sp. ind. b, may rank, for the present, as Acmea (Pvespertina, var.) 
vermicosa. 
? Patella, sp. ind., resembles P. vulgata, but may be an Acmea. 
372-376. There was no opportunity of dissecting the Amherst Chitons ; but among 
373. 
the remaining duplicates of the collection (all of which were obtained and 
brought to England) were the following :— 
Chiton dispar, C. B., Ad. (? non Sby.), including Lepidopleurus Adamsit and. 
var, and Z. tenwisculptus.
