Secondary ridges confounded for the most part with the primaries. 
Longitudinal folds conspicuous B. tottcni. . 
Longitudinal folds obsolete B. humphreysianum. 
Bucdnum. The radula figured by Eberhard, 1. c. pi. 6. fig. 83, under the 
name Bucdnum (^annulatum?y\ does not agree with Loven’s Nassa annu- 
lata, which is Bucdnum ann. pf Lara., and Bullia ann. of more recent con- 
chologists j but it resembles very much Lov^n’s [^Buccinuni] cyaneum ; per- 
haps the name may be misprinted for angulosum, B. angulosum (Gray) being 
a northern species allied to glaciate, cyaneum, and undatum, 
Btdlia rhodostoma (Gray) and -iP. achatina (Lam.). Teeth of the radula, 
Eberhard, 1. c. p. 14, pi. 5. figs. 94 and 96. [Both agree well with Levin’s 
figure for Bidlia annulata (Lam.), and show that this genus resembles Nassa 
in the middle tooth being multidenticulated, and the true northern Bucci- 
nums in the denticulations of the lateral teeth.]

Nassa coronata (Brug.). Teeth of the radula, Eberhard, 1. c. p. 14, pi. 6. 
fig. 6. The radula figured by Eberhard, 1. c. pi. 5. fig. 82, is referred in the 
explanation of the figures to the genus Fusus, and quoted in the text as a 
Bucdnum, but resembles much more those of Nassa figured by Lov6n and 
by Eberhard himself. 
Nassa intermedia, sp. n.. Bunker, Verb, zool.-bot. Gesellsch. Wien, 1866, 
p. 909, Australia. Between N. glans (L.) and N. suturalis (Lam.). 
Nassa reticulata (L.) is destructive to oysters, the shells of which are 
pierced by it. Soubeiran, Bull. Soc. Imp. Acclimat. Paris, iii. 1866, p. 3. 
[Ahssa] Nassodonta insignis, II. Adams, Proc. Zool. Soc. 1866, p. 446,

by a tooth in the outer margin of the apertm’e.

Jjyria. The characters of this genus of operculated Volutce are pointed 
out, and eleven species formerly referred to Valuta are enumerated, by Crosse, 
.Journ. Conch, xiv. pp. 106-116. The change in the situation of the nucleus 
is dependent on the age of the operculum, pp. 336-337.
