FIG. 3. 
CONCHYLIOLITHUS Anomites (linealus) trans- 
versim oval is, decussatim striatus ; striis longitudina- 
libus confertis subtilissimis ; transvcrsis remotioribus 
subelevatls majoribus, raargine integro. S, p. 
A fossil shell. The original Anomia. Perforate, with 
convex valves, transversely oval. The hinge straight and 
patulous, but short, not extending the breadth of the shell. 
Foramen triangular; between the beaks. The surface of 
both valves decussateclly striated ; the longitudinal striae 
close, equal, and very minute, (scarcely visible without the 
assistance of a glass) the transverse broad, somewhat pro- 
minent, and more remote than the striae which they cross; 
but with respect to themselves, approximate, or divided 
only by a small space from each other. The beak of the 
larger valve incurved and pointed ; that of the smaller 
also pointed; and, though shorter than the other beak, 
more prominent than in most other Anornita. of the same 
division. (See Syst. Gen. 6. d. Anoinit^e d. d.) The margin 
is entire, having no indentations of any kind, except a 
very minute, and, in some specimens, scarcely perceptible, 
sinus, which does not in any degree affect the uniform 
convexity of tlie valves. 
Common in limestone, particularly near Castleto?!.
