 109. Columbella pusilla, Sby. Island of St. Vincent, W. T. "=Nitidclla Gouldii,

 120. Columbella lactea, Rve. Gulf Calif., 3Ir. Babb, R.N. [A Nitidella, so tran- 

 sparent that the axis can be seen throughout.] 



122. Columbella Sta-Barbare)isis,C\n'. 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.]

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.]

 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, Amycla (pars), and Nitidella, which do not even belon^- 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. Iktpontics, 



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



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



are from the West Coast].

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

Mr. A. Adams in the eastern seas.] 

 31. Ziziphinus Antonii, Koch, in Phil. Abbild. pi. 1. f. 4. Australia. [Scarcely 



differs from the sliouldered var. of Calliostoma lima (Phil.) C. B. Ad., 



which is called exitniu; Rve., in Brit. Mus. Col.] 

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

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



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



and not from the West Coast.]
