 72. Columbella electroides, Rve. Bay of Guayaquil. 

 74. Columbella Pacifica, Gask. Galapagos. 

 109. Columbella pusilla, Sby. Island of St. Vincent, W. I. lt - Nitidella Gouldii, 



Cpr." [The Nitidella is a distinct Upper Californian species.] 

 120. Columbella lactea, Rve. Gulf Calif., Mr. Babb, R.N. [A. Nitidella, 80 tran- 

 sparent that the axis can be seen throughout.] 



122, 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. S. Lucas, Xantus : Acapulco, New- 

 berry ; Guacomayo, Mus. Smiths. The name (as expressing error) should 

 therefore be altered to C. Reevei, Cpr.] 



123. Columbella spadicea, Phil., MS. in Mus. Cum. Mazatlan. [Described by 



Phil, in Zeit. f. Mai. 1846: B. A. Rep. p. 225.] 



130. Columbella venusta, Rve. [Mazatlan, E. Philippi.'] = C. taniata, Phil, [in 

 Zeit. f. Mai. 1846], not Ad. ajpd Rve., [Voy. Samar. 1850 ; therefore Phil, 

 has precedence. ?= Anachis Gaskoinei, Maz. Cat. no. 652. The Sanaa- 

 rang shell is probably a Nitidella.^ 



Columbella sulcosa^ Sby. " Annaa and Ld. Hood's Islands *. Cuming. 

 Columbella Gouldii, Agass., MS. in Mus. Cum., Nov. 1858. [_ = Amycla Goul-

142. Columbella uncinata, Sby. Is. Muerte, Bay Guayaquil. [Acapulco, Jewett.~\ 



105. Columbella Calif ornica, Rve. April 1859. California. [No authority. 

 Like Anachis lirataJ] 



176. Columbella rorida, Rve. Lord Hood's Island*, Cuming. [Transparent, 

 glossy, with necklace of opake white dots.] 



Genus Meta [ = Conella, Swains, eliminated by Rve. from Columbella; but Anachis, 

 Strombina, Ami/da (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. Lupontice, 

 Kien. Ichaboe, South Africa; [but that of] M. ovuloides, " C. B. Ad., 

 MS." [is shown by his published works to be Jamaica; and the following 

 are from the West Coast]. 



3. Meta ccdonulli, Rve. [La Paz, Mus. Smiths. ; C. S. Lucas, Xantus ; Panama, 



JeivettJ] 



4. Meta coniformis, Sby. [? Panama, Jeicett.~\

[=T.versicolor, Mke., 1850, = Z. Calif ornicus, A. Ad., 1851. Scarcely 

 differs from " Javanicus, Lam.," in Mus. Cum. The form was dredged by 

 Mr. A. Adam? in the eastern seas.] 



Cl. Zhiphimis Antonii, Koch, in Phil. Abbild. pi. 1. f. 4. Australia. [Scarcely 

 differs from the shouldered var. of Calliostoma lima (Phil.) 0. B. Ad!, 

 which is called eximiu , Rve., in Brit. Mus. Col.] 



23. Trochus Japonicus, Dkr., [represents Pomaulax undostts on the east side]. 



24. Trochus digitatus, Desh. Distinct from unguis, with base like yibbei osus. 



Central America. [Mr. Reeve's distinct shell is perhaps not that of D^sh. , 

 and not from the West Coast.] 



26. Trochus tmdosus, Wood. = T. gigas, Anton. California f.
