Anachis subturrita, sp.n., Carpenter, Proc. Calif. Acad. Nat. Sc. 1866, p. 223, 
San Diego, California. 
Seminella, a new genus proposed for a group of small, smooth, shining, 
often iridescent shells inhabiting Polynesia, as Cithara ornata and C. varia 
(Pease) ; they should be classed with the Columbellince, and not with Anachis 
(A. Ad.), which appears to be a conglomerate genus. Pease, Am. Journ. 
Conch, iii. pp. 233, 234. 
Amycla ? chrysalloides, sp. n.. Carpenter, Proc. Calif. Acad. Nat. Sc. 1866,

JEngina fusiformis oxidi^ovata (Pease, Proc. Zool. Soc. 1865) figured in Am. 
Journ. Conch, iii. pi. 23. figs. 6 and 6 j E. tuberculosa (Pease, Proc. Zool. Soc. 
1862) described, ibid. p. 274 j E. nodicostata, variabilis, striata, and parva, 
spp. nn., Pease, 1 . c. pp. 274-276, pi. 23. figs. 8-11, Paumotu islands. 
On the radula of Engina see above (p. 626). 
Marginellid^, 
The radula of Marginella quinqueplicata and elegans, Volvaria 
philippinarum and sp.?, Cystiscus capensis and Persicula clan- 
destina are described and figured by Troschel, L c. pp. 57-60, 
pi. 5. figs. 6-11. All have only one plate in each series, like 
the Volutidae; but it is transversely elongate and multicus- 
pidate, except in Persicula, in which it is short, and has only 
two blunt lobes on each side of the median point, therefore 
resembling more that of the Volutidce. The genus Cylindra 
(Schumacher), hitherto placed among the Mitrce, agrees in the 
radula with Marginella and Volvaria, and is transferred to this 
family by Troschel, who figures that of C. nucea (Meuschen), 
fig. 7 ; in another species, (7. dactylus, he could not find a radula 
(like Dr. Gray), but he has no doubt that there will be one of 
similar type, as may be inferred from the similarity of the 
shell.
