81. Patella Nuttalliana. (Mus, Cum.,= A, pelta, typical. The figure looks more 
like patina. 
140, Be, anilota, 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]. 
57. Turbo marginatus [Rve., non] “ Nutt.” [is a Pacific species, quoted by Messrs. 
Adams as the Collonia marginata of Gray ; but that is a Grignon fossil, olim 
Delphinula (teste type in Brit. Mus.). The Nuttallian shell, published in 
Jay’s Cat., was described by A. Ad. as Chlorostoma funebrale= Chl. meestum, 
auct. Con Jonas, the true 7. mestus being S. American, teste A, Ad. and 
Mus, Cum.)]. 
39. Cyprea onyx iN 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 
“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 Re- 
port, here as elsewhere, is alone responsible. 
56. Fusus turbinelloides, Rve., Jan. 1848. ?Africa, Mus. Cum. [=Stphonalia 
pallida, Br. and Sby.; spines somewhat angular]. 
62. Fusus cancellatus, Lam. “ Unalaska, Kamtschatka, Mus. Cum.” [Doubtless 
the origin of the prevalent locality-error]. 
70. Fusus Nove-Hollandia, Rve., Jan. 1848. N. Hol., 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. Dupetithouarsit, Kien. ] 
91. Fusus Gunneri, Loy., (Tritonium), Ind. Suec. p.12. Greenland. [= T'ro- 
phon multicostatus, Esch. The fig. should be 90, 6; f. 91= Bamffius. ] 
52. Cardium pseudofossile, Rve. “P. Z. 8. 1844.” Hab.?— [Not found in 
P. Z. 8.,=C. Californiense, Desh., 1839, non C, Californianum, Conr., 
1837. This is the Eastern form; the Californian Pvar.= C. blandum, ea 
67. Buccinum modrficatum, Rve., Dec. 1846. Hab. ?— [Agrees sufficiently wel 
with worn specimens from La Paz, Mus. Smiths.,= Siphonalia, closely 
allied to pares. 
62. Buecinum dirum, Rve., Dec. 1846. Hab.?— Mus. Cum. [Worn specimen 
of Chrysodomus Sitchensis, Midd., 1849,= F. incisus, Gld., May re 
110, Buceinum corrugatum, Rve., Feb. 1847. Hab.?— [“ Zruncaria,’ Cuming, 
MS. “ Pisania,’ H. Adams. Vancouver, most abundant. } 
2. Sanguinolaria ovalis, Rve., March 1857. Cent. Am. [?=S. miniata, jun. 
3. S. tellinordes, A. Ad., is the same, adolescent; 5. S. purpurea, Desh., adult. ] 
4, Psammobia maxima, Desh., P. Z. 8. 1854, p. 317, Panama. [Closely resem- 
bling Ps. rubroradiata, Nutt. Puget Sound. } 
19, Mytilus palliopunctatus, Dkx, Cal. and Mazatlan. [No authority for Cal. | 
41. Mytilus bifurcatus, Conr., J.A.N.S. Phil. Hab.? [Conr. assigns his Nuttallian 
species to California; but it is the common Sandw. Is. species, teste Pse. 
he Californian shell, with the same sculpture, is a Septifer, and is the 
S. bifurcatus of Mus, Cum.] 
44. Mytilus Sallei (Dreissina), Recl. Central America. {? On which slope. ] 
62. Mytilus Cumingianus, Recl. Panama, [Septifer.] 
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 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 representing only the judg- 
ment of the latest worker, which may or may not be correct. Synonyms, whether real
