46. Columhella adcula, Rve. California. [No authority.] 

 56. Columhella encaustica, Rve. Gulf California, Lieut. Shipley, Mus. Cum. 

 67. Colujnbella vexillum, Rve. Gulf California. [No authority.] 

 62. Columhella cribraria, Qiioy and Gaim. [i. e. Lam.]= C. guttata, Shy. Panama, 

 common under stones, Cuming. [No other localities given. V. Niti- 

 della crihraria, Maz. Cat. no. 613J 

 72. Columhella electroides, Rve. Bay of Guayaquil. 

 74. Columhella Paci/ica, Gask. Galapagos. 

 ! 109. Columhella piisilla, Shy. Island of St. Vincent, W. I. "=Nitidella Gouldii, 

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

 120. Columhella lactea, Rve. Gulf Calif., Jl/r. £ahb, JR.N. [A A'itidella, so tran- 

 sparent that the axis can be seen throughout.] 



122. Coltimbella Sta-Barharensis, 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, Xantm : Acapulco, JS'eic- 

 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. Columhella venmfa, Rve. [Mazatlan, JE. Philippi.~\ = C. tesniata, Phil, [in 



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



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



rang shell is probably a Nitidella.'] 

 132. Columhella sulcosa, Sby. Annaa and Ld. Hood's Islands *. Cuminff. 

 135. Columhella Oouldii, Agass., MS. in Mus. Cum., Nov. 1858, \_ = Amyda Goul- 



diana, Agass., Atlantic; non Nitidella Gouldii, Cpr.] 

 142. Columhella uncinata, Sby. Is. Muerte, Bay Guayaquil. [Acapulco, Jeioett.'j 

 105. Columhella Californica, Rve. April 1859. California. [No authorit\'. 



Like Anachis lirata.] 

 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 Columhella; but Anachis, 



Stromhina, 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. Bupontice, 



Kien. — Ichaboe, South Africa; [but that of] 3/. oywfojtZes, "C. B. Ad., 



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



are from the West Coast]. 



3. Ileta cedonnlU, Rve. [La Paz, Mus. Smiths. ; 0. S. Lucas, Xantus ; Panama, 



Je^pett.'] 



4. Mela coniformis, Shy. [? Panama, Jewett.'] 



24. Ziziphinus luridus, Nutt., MS. in Mus. Cum. California. [Is not known from 



the American coast; comp. Sandwich Islands.] 



25. Ziziphinus eximius, Rve., P. Z. S. 1842. Panama, sandy mud, 10 fms. 



\ = T. versicolor, Mke., 1850, = 2'. Californicus, A. Ad.," 1851. Scarcely 

 differs from " Java)iicus, Lam.," in Mus. Cum. The form was dredged by 

 ' Mr. A. Adams in the eastern seas.] 



CI. Zizi]>hi'ius Antonii, Koch, in Phil. Abbild. pi. 1. f. 4. Australia. [Scarr^ely 

 dillers from the shouldered var. of Calliostoma lima (Phil.) 0. D. Ad., 

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



23. Trochus Juponicus, Dkr., [represents Fomaulax undosus on the east side]. 



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



Central America. [Mr. Reeve's distinct shell is perhaps not that of Di-s!i. , 

 and not from the West Coast.] 



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