186 CONIDA. 
remote from the suture. Operculum ovate-pyriform. P. carinata, 
Phil. (lviii, 35). 
RAPHITOMA, Bellardi. Fusiform, turriculated, spirally sculp- 
tured; canal short; sinus very small. 22 sp. occur on the Dat- 
matian coast alone, but the cancellated species may be more 
properly referred to Clathurella. There are a number of Italian 
tertiary species. P. ringens, Bellardi (lviii, 36). 
TARANIS, Jeffreys. Shell minute, cancellated, whorls angulated, 
slightly exserted at base, aperture pyriform, outer lip thin, simple, 
sinus obsolete, canal short. No operculum. TZ. Mérchii, Malm. 
(lviii, 37). 
THESBIA, Jeffreys. Shell thin, rather smooth, somewhat tumid, 
with a short spire and irregularly contorted apex, aperture 
slightly expanded, the outer lip thin, with distinct sinus, canal 
short, columella simple. Noopereulum. 7’. nana, Lovén (lviii, 38). 
PLEUROTOMELLA, Verrill. Shell somewhat turreted, apical 
whorls smooth, others shouldered and ribbed, but with a smooth 
concave band below the sutures; outer lip very thin, sharp, with 
a wide, deep sinus above. No operculum. Animal without eyes. 
P. Packardii, Verrill. N. Engl. Coast. 
BoRSONTA, Bellardi. (Oligotoma, Bell.) Shell fusiform, with a 
plication upon the middle of the columella. Miocene; Europe. 
P. prima, Bellardi |lviii, 39). 
CORDIERA, Roualt. (Scobinella, Conr. Aphanitoma, Bellardi.) 
Shell fusiform, with two columellar plaits. This and the last 
subgenus should probably be merged in one. Eocene, Miocene; 
Kur., America. P. Pyrenaica, Roualt. (lviii, 40). 
Hatra, Risso. 
Etym.—Halios, marine. Syn.—Priamus, Beck. 
Distr.—H. Priamus, Lam. (lvili, 41). Spain. 
Shell oblong-ovate, ventricose, thin, polished ; spire produced, 
apex obtuse, papillary ; columella curved, truncate anteriorly ; 
outer lip simple, thin, effuse, slightly sinuated near the fore-part. 
No operculum. A single species occurs very rarely in collec- 
tions,and was supposed to inhabit the Western Coast of Spain; it 
occurs in the Italian tertiary. Dr. P. Fischer has examined the 
animal of this singular shell, and finds it to be related to Pleuro- 
toma. Known to science for more than a century, the habitat of 
Halia has remained unknown until quite recently; it is now cer- 
tain that it lives off Cadiz, Spain. 
Famity CONID#. 
Teeth subulate, in two series, ona tubular prolongation of the 
retractile proboscis, with a bundle of sharp, subulate teeth at the 
extremity. Head with a produced tubular veil; tentacles subu- 
late, eyes on bulgings or slight truncatures on the outer side of
