104 TEREBRA. 
TEL’EBOIS. Montf. A genus of microscopic Foraminifera. 
TELESCO’PIUM. Montf. Ceriruium Telescopiwm, Auct. 
TEL'LINA. Auct. Fam. Nymphacea, Lam. Conchacea, Bl. 
Descr. Sub-equivalve, inequilateral, compressed, rounded ante- 
riorly, sub-rostrated posteriorly, with the posterior ventral mar- 
gin flexuous; hinge with two cardinal and generally two lateral, 
teeth, in each valve; muscular impressions, two in each valve, 
remote; palleal impression with a large sinus. Obs. The irre- 
gular fold in the posterior margin, distinguishes this genus from 
others, which it nearly resembles. It is composed of some bi- 
valves of great beauty and variety. Fig. 105, T. radiata. 106, 
T. lingua-felis. 
TELLINI'DES. Fam. Nymphacea, Lam. Descr. Sub-equivalve, 
inequilateral, transverse, compressed, rounded anteriorly, slightly 
beaked or angulated posteriorly ; hinge with two cardinal teeth 
in each valve, and one lateral tooth in one valve, very near the 
cardinal teeth. Muscular impressions, two, distant; palleal im- 
pression with a large sinus. Obs. This genus is distinguished 
from Tellina, in having but one lateral tooth near the cardinal 
teeth. Fig. 107, T. rosea. 
TENUIPEDES. (Tenuwis, slender; pedes, feet.) The second sec- 
T 
tion of the order Conchifera Dimyaria, divided into the families 
Mactracea, Corbulacea, Lithophaga, Nymphacea. 
ERA’CLITA. Schum. Conia, Auct. 
TEREBEL'LUM. (Terebra, an augur?) Fam. Convolute, Lam. 
oF 
Angyostomata, Bl. Descr. Smooth, slender, oblong, sub-cylin- 
drical ; spire obtuse, short, sometimes hidden; (Seraphs, Montf.) 
Aperture long, narrow posterior, wider anteriorly; outer-lip 
slightly thickened, truncated, unconnected at the base with the 
columella; inner-lip thin, smooth, nearly straight, spread over 
a portion of the body whorl, continued in a ridge above the 
sutures of the spire. Obs. Montfort has separated the fossil 
species, with hidden spires, under the name Seraphs. (T. con- 
volutum, Lam.) Only one recent species is known, of which 
there are several varieties, one spotted, one marked with sub- 
spiral lines, a third in patches. Fig. 451, T. convolutum. Fig. 
452, T. subulatum. 
ERE’BRATING SHELLS (Terebro, to pierce.) are those 
which reside in holes pierced in rocks, wood, &c. by means of some 
corrosive secretion of the animal. Hx. Pholas, Teredo, &c. 
TEREBRA. (An augur, a piercer.) Fam. Purpurifera, Lam. 
Entomostomata, Bl. Descr, Subulate, elongated, pointed, tur- 
rited ; spire long, consisting of numerous whorls ; aperture small, 
terminating in a short, reflected canal; outer-lip thin, colu- 
mella tortuous; operculum horny. Obs. It is difficult to dis- 
tinguish some of the shorter species of Terebra from the 
longer species of Buccinum, although in general there is a great
