shell. He arms himself with a long spear, the shaft made o. 
light deal, to the end of which is fastened a strip of wood placed 
transversely, but driven full of teeth made of bone, resembling 
exactly a long comb with the teeth very wide apart. A squaw 
sits in the stern of the canoe, and paddles it slowly along, whilst 
the Indian with the spear stands in the bow. He now stabs the 
comb-like instrument into the sand at the bottom of the water, 
and after giving two or three such stabs draws it up to look at it; 
if he has been successful perhaps four or five Dentalia have been 
impaled on the teeth of the spear.’ At one period, perhaps a 
remote one in the history of the inland tribes of Indians, Den- 
talia were worn as ornaments; these are found in old oraves, 
quite 1000 miles from the sea, mixed with stone beads and small 
bits of nacre of the Halhotis, of an irregular shape, but with a 
small hole drilled through e: ich piece. ”__ JEFFREYS, Brit. Conch. 
D. ergasticum, a monster species, dredged by the “ 'Travail- 
leur,” is nearly four inches (9 cm.) long. 
ANTAL E, Aldrov. (Pyrgopolon, Mane Entalium, Defrance. 
Pharetrium, Konig.) Shell tubular, much prolonged, smooth, 
the posterior end with entire margin, the internal tube slightly 
projecting,and usually with a roundish opening. D. Tarentinum, 
Lam. Europe. 
ENTALIS, Gray, 1840. (Antalis H. and A. Ad.,ex parte.) Shell 
tube-like, slightly curved, longitudinally ribbed or sometimes 
striated, ‘gradually tapering towards the posterior end, which 
has the margin on the ventral or convex side provided with a 
short and broad fissure. Type, D.entalis, Linn. D. Delesserti, 
Chenu (ciii, 1). The posterior end is usually longitudinally 
striated even when these striz or ribbings become obsolete 
towards the aperture. The supplementary or embryonal pro- 
jecting tube is not always present, being frequently lost. 
FUSTIARTA, Stoliczka, 1868. Shell tubular, thin, usually slightly 
curved, § smooth, posterior end with a long, ‘linear slit on or near 
the ventral side. D. eburneum, Lam. 
SuspraMIty SIPHONODENTALIINA. 
Posterior aperture of the shell entire or with several notches, 
and without supplementary tube. Foot elongated, worm- like, 
provided at the tip with a circular disk, the edges of which are 
beset with papille ; edge of the lateral plates of the radula dis- 
tinctly tridentate. (Order Siphonopoda, Sars.) 
The shells resemble the Dentaliinz, but as they appear usually 
to inhabit deep waters they always consist of a thin substance ; 
the posterior end is generally less pointed and more widely 
opened.
