81. Patella Nuttalliana. [Mus. Cum., =A. pelta, typical. The figure looks more 



like 2mtina.~\ 

 140. Patella mamillata, Nutt. [non Esch., is an elevated, stunted form of the black 



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



stand as limatula}. 



64. Fissurella densiclathrata [is distinct from G. aspera. Sta. Barbara, Jewett]. 

 67. Turbo marginatm [Rve., non] " Nutt." 



Adams as the Collonia marginata of < 



Delphinula (test3 type in Brit. Mus. 



Jay's Cat, was described by A. Ad. as CJilorostoma funebrale= Chi. 



auct. (non Jonas, the true T. mcestus being S. American, tesle A. Ad. and 



Mus. Cum.)]. 

 39. Cypr&a onyx [is the E. Indian, C. spadicea the similar S. Diegan species]. 



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

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

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

 refers to the figure. For the remarks enclosed in [ ] the writer of this lie- 

 port, here as elsewhere, is alone responsible. 



50. Fasus turbinelloides, Rve., Jan. 1848. ? Africa, Mus. Cum. \_-Siphonalia 



pallida, Br. and Sby. ; spines somewhat angular], 

 02. Fasus cancellatus, Lain. " Unalaska, Kamtschatka, Mus. Cum." [Doubtless 



the origin of the prevalent locality-error]. 

 '/o. Futus Nova-Hollandi*, Rve., Jan/ 1848. N. Hoi., Metcnlfe. [As Mr. Met- 



calfe gave numerous West Coast shells to Brit. Mus. und' j r locality "N.H.," 



this shell also was probably from W. Mexico, = -P. Dupclithouarsiij Kien.] 

 91. Fusus Gunneri, Lov., (Tritonium), Ind. Snec. p. 12. Greenland. [=Jro- 



phon multicostatus, Esch. The iig. should be 93, 6 ; f. 91 = Bamffius.~] 

 52. Curdium pseudofossile, Rve. " P. Z. S. 1844." Hab. ? [Not found in 



P. Z. S.,= C. Calif orniense, Desh., 1839, non C. Calif nrnianum, Conr., 



1837. This is the Eastern form; the 0&:ifomian ?var.= C. bland/on, Gld.^ 

 67. Buccinum modificatum, Rve., Dec. 184o. llab. ? [Agrees sufficiently well 



with worn specimens from La Paz, Mus. Smiths., ~ &iphonalia } closely 



allied to pallida.~\ 

 62. Buccinum diruin^ Rve., Dec. 1846. Hab. ? Mus. Cum. [Worn specimen 



of CArysodomus Sitchensis, Midd., 1849, = JP. incisus, Old., May 18i9.] 

 110. Buccinum corruffatum, Rve., Feb. 1847. Ilab. ? [" 'Iruncaria" Cuming, 



MS. " Pisania" H. Adams. Vancouver, most abundant.] 

 2. Sanguinolaria omlis, Rve., March 1857. Cent. Am. [?= miniata, jun. 



3. S. tellinoides, A. Ad., is the same, adolescent; 5. S. purpurea, Desh., adult.] 

 4. Psammobia maxima, Desh , P. Z. S. 1854, p. 317. Panama. [Closely resem- 

 bling Ps. rubroradiata, Nutt. Puget Sound.] 



19. Mi/tilm ralliopunctatus, Dkr. Cal. and Mazatlan. [No authority for Cal.l 

 41. Mytilus bifurcatus, Conr.,. J. A. N.S.Phil. Hab.? [Conr. assigns his Nuttallian 



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



The Ca'ifornian shell, with the same sculpture, is a Scptifer, and is the 



S. bifurcatns of Mus. Cum.] 



44. Mytilus Sallei (Drcissina), Reel. Central America. [? On which slope.] 

 52. Mytilus Cuminyianus, Reel. Panama. [_Septifer.~\ 

 60. Mytilus c/lom'>ratm, 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 ncces- 

 t>ary 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 modern genera, the student is greatly aided in his search 

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

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

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

 ment of the latest worker, which may or may not be correct, i^iionvms, whether real
