342 TESTACEOUS MOLLUSCA. 
lanceolate ; inside ochraceous yellow. 2%. Meaico. The epidermis 
is usually ochraceous in front. 
AMPHIDESMA ZEBUENSE (t. 12, f. 7), Hanl. Z. P. 1844.—Reeve, 
I. Amp. f. 25.—SrEMELE GRatIOsA, Adams, teste Reeve. Obliquely 
ovate, solid, very inequilateral, slightly convex, whitish, with pale 
red rays, and short crowded concentric lamelle, whose intervals are 
usually divided by a concentric raised stria; anterior side short, 
rounded; hinder margin incurved; ventral edge strongly arcuated ; 
inside white, with two red rays at the umbones. 13...2.  Philip- 
pines. The colouring matter seems deposited on the lamella only. 
The lunule is rather large for the genus. 
AMPHIDESMA RADIATUM (t. 12, f. 8, as A. Australe), Say, J. Ae. 
Philad. vol. 5 (1825), p. 220.—A. suprruNncaAtTUM, Reeve (as of Sow.), 
Ic. Amp. f. 11.—Sow. Spee. Con. pt. 2,4 Amp. f. 3. Transversely 
suborbicular, subequilateral, bluntly subangulated and flexuous in 
front, rounded behind, not solid, convex or subventricose, yellowish 
white, with numerous narrow rays of ruddy flesh-colour on the disk, 
and short waved lines of the same hue on the two slopes, rough with 
concentric membranaceous wrinkles, and almost imperceptibly minute 
radiating striole ; slope of the dorsal edges decided, subequal ; inside 
yellow. 13. Jamaica. This shell was figured as Australe, having 
been found so named in a collection arranged by Mr. Sowerby. It 
does not agree, however, with the type, although not unlike the drawing 
in the * Conchological Illustrations.’ It agrees fairly with the descrip- 
tion of A. JAvanum in Adams’ Jamaica Shells (Proc. Bost. ii. 1845).

—feeve, I. Amp. f.6. Suborbicular, convex or subventricose, rather 
thin, subequilateral, pmk or flesh-coloured without, orange within, 
concentrically lamellated throughout; lamelle frequent, membrana- 
ceous, serrated at the edge, their intervals set with most crowded 
minute radiating wrinkles; ventral edge rounded, entire; both dorsal 
edges short, straightish, and about equally sloping; anterior slope 
impressed. 1...1. Philippines.

Reeve, I. Amp. f. 33, probably. Obovate, convex, solid, subequilateral,

pit and beneath the lunule. 2...23. Philippines.
