81. Patella Nuttalliana. [Mu3. Cum.,=^. ^efta^ tj'pioal, Tlie figure looks more 



like patina.'] 

 140. Patella mamillata, Niitt. [non Esch., is an elevated, stunted form of the Hack 

 ? var. of scabra, Nutt. The name being preoccupied, this distinct form may 

 stand as Umatula']. 



64. Fissurella densiclathrata [is distinct from O. aspera. Sta. Barbara, JeiDetf]. 



til. Turho marginatus [Rve., non] "Nutt." [is a Pacific species, quoted by Messrs. 

 Adams as the Collonia marginata of Gray ; but that is a Gripnon fossil, olim 

 Delphinula (teste type in Brit. Mus.). The Nuttallian shell, published in 

 Jay's Cat., was described by A. Ad. as Cldorostoma funehrale= Vhl. mosstum, 

 auct. (non Jonas, the true 1\ mcestus being S. American, teste A. \d. aud 

 Mus. Cum.)]. 



39. Cyprcea onyx ps the E. Indian, C. spadicea the similar S. Diegan species]. 



The follomng species, either quoted from the W. Coast, or known to in- 

 habit it, or connected with it by synonymy, have been observed in lleeve's 

 'Conch. Ic' since the date of the last Eeport. The number of the species also 

 refers to the figure. Por the remarks enclosed in [ ] the writer of this Ke- 

 port, here as elsewhere, is alone responsible.

 the origin of the prevalent locality-error]. 



#'o. FusKS Novee-Holhiidia, Rve., Jan. 1848. N. Hoi., Metcalfe. [As Mr. Met- 

 calfe gave numerous West Coast shells to Brit. Mus. under locality " N.H.," 

 this shell also was probably from W. Mexico, = -F. Dupetilliiniarm, Kien.]

 P. Z. S.,= C. Californiense, Desh., 1839, non C. Califnrii.iitimm, Conr.,

67. Biiccinum mochficatum, Rve., Dec. 1840. Hab. ? — [Agrees sufficiently well 

 with worn specimens fi:om La Paz, Mus. Smiths., = &))^o;ia&, closely 

 allied to pallida.'] 



62. Succiniim dirum, Rve., Dec. 1846. Hab.? — Mus. Cum. [Worn specimen 



of Chrysodomus Sitchensis, Midd., 1849,= P. incisus, Gld., May 1849.]

41. J/(//i/i(S J(/(u-cote, Conr., J. A. N.S.Phil. Hab.? [Conv. assigns his Nuttalban 

 species to California ; but it is the common Sandw. Is. species, teste Pse. 

 The Californian shell, with the same sculpture, is a Septifer, and is the 

 S. bifarcatus of Mus. Cum.] 



44. Mytilus Sallei (Dreissina), Reel. Central America. [F On which slope.] 



62. Mytilus Cmningianus, Reel. Panama. \_Septifei\] 



60. Mytilus glomeratus, Gld. Hab.? — * [Gould's species is from California, but 

 the name is attached to a very different shell in Mus. Cum.] 



* Several species occur in the recent monographs without locality, which are well 

 known to inhabit the W. Coast. This is partly due to the writer not thinking it neces- 

 sary to refer to published books for information, and partly to the changes which have of 

 late years been made in the principal authority, viz. the Cumingian collection. By the 

 redistribution of species into the modem genera, the student is greatly aided in his search 

 for special forms ; but, for the sake of uniformity, the autograph labels of colleetors or 

 Uescribers of species are generally rejected, the names being either in the handwriting of 

 the clerk or from the printed index in the monograph, and representing only the judg- 

 ment of the latest worker, which may or may not be correct. iS^nonyms, whether re^l
