Gabb; Priscoficus Hornit, Gabb; Pric. oregonensis, Con., and Pris. Smithii ? 
Sowerby. 
The genus Perissolax, as pointed out by Gabb, appears better classified in the 
rusin@ of the Mvrrcipz. The new genera Ficopsis and Priscoficus appear to 
include a varied number of different shells, and unless the type species of these 
supposed new genera are pointed out they seem to be worthless. Originals of 
Pyrula Smithii, Sow., which I have examined in London, show that the species is 
a Rapa. 
V. Family,—CASSIDID 4, p. 61. 
( CAssIDEA, Troschel, Geb. d. Schnecken, I, p. 220). 
The genera composing this family are Cassis, Semicassis, Phaliwm, Galcodea 
(Link. or Linn. ? Cassidaria, Lam.)., Oniscia, Pachybatron. 
In Am. Jour. Conch., I, 1865, p. 26, is a Galeodaria, Conrad, quoted as sub- 
genus of Galeodea, and besides Morwm, Bolten, distinguished as a separate genus. 
In Check list of eocene fossils (Smiths. Mis. Coll., No. 200, 1866, p- 15) 
Conrad quotes from his lower eocene rocks (cretaceous ?) Galeodea petrosa, Con., 
Semicassis ? biliratus and Semic.? petrosus, Con.; the two last named species 
are apparently the same which the author has placed in Am. Jour. Conch., I, 
1865, p. 150, in his genus Doliopsis, mentioned in the former family. 
VI. Family, PLEUROTOMUIDZ, p. 63. 
( PLEvROTOMACEA, Troschel, Geb. d. Schnecken, II, 1866, p. 88). 
Numerous new genera and higher sub-divisions have been lately distinguished 
in this family. 
A. Adams describes in Ann. mag. nat. hist., Ser. III, VI, p. 331, and XV, 
p- 322, the new genera Zafra, Mitromorpha, and Cytharopsis. 
Conrad describes a genus, Moniliopsis, in Am. Jour. Conch., I, 1865, p. 148, 
and another one as Cochlispira, ibid., p. 210. 
Stimpson (Am. Jour. Conch., I, p. 62) proposes, after having observed the 
animal of one of the species, to establish for the genus Clionella, Gray, a distinct 
family, Czzowzrzip”. The lateral teeth resemble those of Plewrotoma and Halia, 
but there is besides a central tooth present. The author considers this distinction 
sufficient to refer the Czzrowzzz1p2 to a distinct sub-order from the ToxoGLossaTA 
under the name of Tomocuossata ! 
Conrad in Am. Jour. Conch., I, p. 20, quotes in the family Przvrorourpz also 
the genera Hvilia, Conr., Hucheilodon, Gabb, and Scabinella, Conr. 
The name Cithara, Klein (Ostr,, 1753, p. 97, pl. V, fig. 105) refers to Harpa 
minor. 
Dr. v. Koenen (“Ueber Conorbis and Cryptoconus,” Marburg, 1867) proposes for 
some fossil species the name Cryptoconus, an intermediate form between Conus 
and Conorbis of Swainson; there seems, however, great difficulty in distinguishing 
Cryptoconus from the last named form.
