128 FUSIDA. 
Conr. (xlvii, 74). Eocene; Alabama. Scarcely distinct from 
the typical Fuse. 
TURRISPIRA, Conrad. Has not been characterized, and does 
not seem to differ from Fusus. F. Salebrosa, Conrad (xlvii, 75). 
Eocene; Alabama. 
PRISCOFUSUS, Conrad. Founded on Fusus geniculus, Conrad, 
avery poorly preserved or figured fossil; the type has ‘been 
lost for twenty years. The species is wholly unrecognizable, 
and should be expunged from nomenclature. For this rubbish 
Mr. Conrad has proposed a genus Priscofusus, but with neither 
figure nor diagnosis.” —Datu, Proc. Calif. Acad., 1817. F. geni- 
culus, Conrad (xlvii, 76). Eocene; Astoria, Oregon. 
SERRIFUSUS, Meek. Shell short-fusiform ; body-volution large, 
and bi- or tricarinate, with carinz more or less nodose; spire 
and canal moderate, the latter bent and more or less twisted ; 
outer lip broadly but slightly sinuous in outline, between the 
upper carina and the suture. /. Dakotensis, Meek and Hayden. 
Cretaceous ; Dakotah. 
This form so much resembles the recent Fusus (Hemifusus) 
proboscidiferus, Lam., that it might well be considered a fossil 
form of the same group. 
JANIA, Bellardi. Shell subfusiform; spire elongate; mouth 
scarcely canaliculate behind; lip marginate, nodose or plicate 
within; columella uniplicate anteriorly and posteriorly ; canal 
short recurved. F. angulosus, Brocchi (xlvii, 77). Tertiary ; 
Italy. 
MAYERIA, Bellardi. Ovate-fusiform, spire short, but slightly 
acute; whorls very sharply carinate in the middle; columella 
smooth, rather straight in front, canal moderate. F. acutissimus, 
Bellardi (xlvii, 81). Tertiary ; Italy. 
ANURA, Bellardi. Shell turreted, ovate ventricose; whorls 
convex ; mouth orbicular or suborbicular ; lip somewhat arcuate, 
exteriorly subvaricose in the adult, interiorly margined and 
smooth; canal scarcely produced; columella slightly contorted, 
smooth. /. inflatus, Brocchi (xlvii, 79). Tertiary ; Italy. 
MITRZFUSUS, Bellardi. Elongated, mitreeform ; spire very long 
and acute; whorls numerous, the last scarcely depressed in front ; 
mouth narrow, long; lip simple ; canal long, produced in the axis 
of the shell. F. orditus, Bell. et Mich. (xlvii, 80). Tertiary; Italy. 
GENEA, Bellardi. Shell subfusiform, long, narrow; spire long, 
very acute ; mouth long, narrow; lip simple; columella smooth, 
but slightly arcuate; canal very short, wide, straight. FF. Bonellit, 
Gené (xlvii, 78). Tertiary ; Italy. 
Arer, Conrad. 
Distr.—2 sp. Red Sea to Manilia, Senegal. A. Blosvillei, Desh. 
(xlvii, 82).
