NOTES 
!)7. A species of Mactra, resembling the M. gigantea, but thinner more 
depressed and more elongated transversely. 
98. Resembling the last, but rather more prominent at the beaks, probably 
the young, or a mere variety of M. gigantea. 
144. A Tellina, apparently confounded with the T. sulphurea; but the 
beak is greatly shorter, the ligament is larger and the transverse strife deeper 
and sharper ; the colour is the same in both. 
179 — 186. From 179 to 181, a very much rounded Tellina of white colour, 
ligament very large, inflexion of the beak small transverse strife irregular, 
tine length and breadth about 3 inches 182. A minutely decussated shell, 
with longitudinal and transverse strim, colour white, yellowish at the beak ; 
ligament moderate ; pit very large, smooth ; length and breadth about 1 
inch. It has a truncated appearance 183. A very thin slightly-beaked 
Tellen of a pale-flesh colour, distinctly rayed with white. 
252 — 258. From 252 to 254 is a species nearly allied to C. morphina, 
differing principally in the colouring, the longitudinal rays being absent ; and 
being slightly more compressed. 258, 257, differ from C. morphina only in 
being rather paler. 257 and 258, resemble C. castanea, but are of a pale- 
yellow colour. 
275. Differs from C. chione in being slightly thicker, and having the 
epidermis dull. 
294. One species of Cytheria. 
309. A very old and rugose specimen of C. flexuosa. 
373 — 380. Six species of Venus, the two first resembling V. scripta, but 
greatly larger, coarser, and with stronger transverse striae. 375. A very globose 
thin shell, much worn, and the characters obscure. 376. A pretty species 
between V. papilionacea, and V. paphia in appearance. 379. Resembles 
V. caliste, but the ribs are very thick and smooth. 380. A slightly 
compressed V. calisto. 
381, 383. Coquille rare et preeieuse, surtout lorsqu'on possede les deux 
valves du meme individu. Lamark. Anim. Sans. Vert. vol. VI. p. 4. 
457, 458. Two species of Cardita.
