Columbella electroides, Rve. Bay of Guayaquil. 
Columbella Pacifica, Gask. Galapagos. 
Columbella pusilla, Sby. Island of St. Vincent, W. I. “= Mitidella Gouldii, 
Cpr.” [The Mitidella is a distinct Upper Californian species. ] 
Columbella lactea, Rve. Gulf Calif., Mr. Babb, R.N. [A Nitidella, so tran- 
sparent that the axis can be seen throughout. | 
Columbella Sta-Barbarensis, Cpr. Sta. Barbara. ‘“ Not merely faintly striated, 
teste Cpr., but unusually grooved.” {Described from a worn specimen 
in Jewett’s Col., and named to mark a more northern limit to the genus 
than had been assigned by Forbes. The label was probably incorrect, as the 
shell lives in the tropical fauna, C. 8. Lucas, Xantus: Acapulco, New- 
berry ; Guacomayo, Mus. Smiths. The name (as expressing error) should 
therefore be altered to C. Reevei, Cpr. ]

Phil. in Zeit. f. Mal. 1846: B. A. Rep. p. 225.] 
Columbella venusta, Rve. (Mazatlan, E. Philippi.) =C. teniata, Phil. [in 
Zeit. f. Mal. 1846], not Ad. and Rve., [ Voy. Samar. 1850; therefore Phil.

Strombina, Amycla (pars), and Nitidella, which do not even belong to 
the same family, if the opercula are to be trusted, are left in the old place. 
Of the six species, the author only knew the locality for one], M. Dupontia, 
Kien.—Ichaboe, South Africa; [but that of] M. owdoides, “C. B. Ad., 
MS.” [is shown by his published works to be Jamaica; and the following 
are from the West Coast]. 
. Meta cedonulh, Rve. {La Paz, Mus. Smiths.; C. S. Lucas, Xantus; Panama, 
Jewett. |

[=T. versicolor, Mke., 1850,=Z. Californicus, A. Ad., 1851. Scarcely 
differs from “ Javanicus, Lam.,” in Mus.Cum. The form was dredged by 
Mr. A. Adams in the eastern seas. 
Zixiphinus Antonit, Koch, in Phil. Abbild. pl. 1. f.4. Australia. [Scarcely 
differs from the shouldered var. of Calliostoma lima (Phil.) d B. Adi, 
which is called eximius, Rve., in Brit. Mus. Col. ] 
Trochus Japonicus, Dkx., [represents Pomaulax undosus on the east side]. 
Trochus digitatus, Desh. Distinct from wnguis, with base like gibberosus. 
Central America. [Mr. Reeve’s distinct shell is perhaps not that of Desh., 
and not from the West Coast. ] 
Trochus undosus, Wood,=T. gigas, Anton. California +. 
* Vide Report, 1856, p. 168, note §§. 
_ t+ Mr. Reeve states that, although this species is most like gibberosus, “‘ Messrs. Gray and
