ANODON PICTUS. 
(Lot 972.) 
A. testé ovata, compress, radiatd, umbombus retusis ; margine liga- 
mentali levato, angzulato; lamind cardinal brevi, latd, vix concavd, 
sinu producto leviter curvato terminatda. 
Shell oval, compressed, radiated, umbones retuse, ligamental margin 
elevated and angulated; hinge margin short, broad, slightly 
concave, terminating in a lengthened slightly-curved sinus; 
umbones retuse; inside yellowish white. 
Anodonta intermedia? — Lam. Syst. vol. vi. p. 86. 
Un tess the modification of the hinge margin, and the sinu 
by which it is terminated, is taken into primary considera- 
tion, I conceive no other specific characters will sufficiently | 
distinguish the shells of this most intricate family, M. La- 
marck has characterized them with greater precision than 
any other writer; but the unfortunate deprivation of sight, 
with which this great naturalist is now afflicted, compels 
him to trust to the sight of another; an infirmity which, 
while it calls for the sympathy of every generous mind, has 
prevented the last volume of the Systéme from appearing 
with that accuracy which its illustrious author would other- 
wise have given to it.
