SCALARIA undosa. 
TAB. DLXXVII. —fig. 4. 
Spec. Char. Subulate, transversely striated,, costated; 
costae numerous, slightly elevated, crossed by 
the striae, terminating in a band that covers the 
base ; volutions united, convex. 
Costa; about twenty-four upon each whorl, waved, broad, 
and very slightly raised; the base is nearly smooth, being 
only marked lightly by lines continuing from the costae. 
An imperfect specimen from Barton is in Mr. Good- 
hall’s collection. 
SCALARIA reticulata. 
TAB. DLXXVII.— /g. 5. 
Spec. Char. Subulate, short; surface reticulated; 
whorls united ; columella hollow ; base smooth. 
Syn. Turbo reticulatus. Brander,jig. 27. 
Eight whorls compose this shell, which is only about 
half an inch long ; nine or ten prominent transverse striae 
cross numerous not more prominent ribs, forming a net- 
work that covers the convex whorls, and is bounded by 
a nearly smooth band extended over the base. 
Presented many years ago by Miss Bemister : found at 
Barton. Miss Teed has in her cabinet a broken indivi- 
dual above an inch long. 
SCALARIA semicostata. 
TAB. DLXXVIL— fig. 6. 
This figure is from a nearly full-grown individual, such 
as are not uncommon at Barton. A small one only has 
been represented in the middle of tab. 16. In the vici- 
nity of Paris a Scalaria is found still longer, with more 
numerous costae and less distinct striae, but apparently 
the same species ; I have received it as S. plicata from 
Mons. Deshayes*
