304. 145. Quoted by Gmelin for a variety of his Fenus purpurascens, and is a doubtful fi- 
gure. Klein’s t. 11. f. 57- is a copy. 
305. 138. Venus Pensylvanica. 
306. 139. Venus circinata; and from this figure Gmelin has erroneously followed Schroeter 
in describing a separate species, with the hame of Venus rubra. 
307. 140. Venus Dione. 
308. 141. Is the Venus No. 66. of Schroeters Einleitung; and if more than a variety, is 
nearly allied to Mactra plicataria. 
310. 146. Venus divaricata. 
311. 147. The Venus No. 63. of Schroeters Einleitung, which is the Venus pusilla of 
Gmelin, is wholly described from this figure; and it is quoted by Adanson for 
« Le Jagon,” which is the Venus eburnea of Gmelin. The same shell has been 
figured as a Tellina in the Encyclopedie Methodique, t. 292. f. 7- and I am not 
otherwise acquainted with the species. 
312. 148. Venus discors. 
313. 149. Venus pectinata. 
314. 150. Cardium pectinatum. 
315. 151. Cardium Unedo. 
— 152. Cardium Fragum. 
316. 153. Cardium medium. 
317. 154. Cardium exiguum; and the name was first given by Gmelin to a species which 
Schroeter had constituted from this figure. 
318. 155. Cardium Cardissa. 
319. 156. Cardium humanum. 
320. 157. Cardium roseum. 
321. 158. Cardium aculeatum. 
322. 159. Cardium muricatum. 
323. 160. Cardium Isocardia. This figure appears to have been engraved by simply tracing 
Buonannfs fig. 95. on the copper; and it has again been copied from Lister by 
Petiver in his Gazophylacium, t, 152. f. 7- 
324. l6l. Cardium echinatum; and it is copied from the Historia Animalium Anglise, t. 5. 
f. 33. 
325. 162. A young shell of Cardium echinatum. 
326. 163. Variety of Cardium muricatum. 
327- 164. Cardium costatum; and Lister has copied this figure from one at p. 27 of Columna 
“ de Purpura.” 
328. 165. Cardium maculatum; and the name was first given by Gmelin to a description 
which Schroeter had taken from this figure. 
329. 166. Cardium tuberculatum. 
330. 167. Cardium ringens. 
331. 168. Cardium leucostomum. 
332. 169. Cardium lavigatum. 
333. 170. Cardium rusticum. 
334. 171. Cardium edule; and is taken from the Historia Animalium Anglise, t. 5. f. 34. 
335. 172. Is quoted by Lamarck for his Venus Corbis, which is a species nearly allied to 
Vemis reticulata; and Klein, in his Methodus Ostracolog. 1.10. f. 54. has copied 
this figure. 
336. 173. Venus puerpera. 
337. 174. Venus tigerina. 
338. 175. Venus granulata; and Gmelin has followed Schroeter in describing this figure as 
a separate species, with the name of Venus violacea. 
339. 176. Tellina carnaria. 
340. 177 - From this uncertain figure the Venus No. 69. of Schroeters Einleitung, and the 
Venus spadicea of Gmelin, have been constituted; and by Meuschen, in the 
Museum Geversianum, No. 1621, it is quoted for Cardium ciliare. 
341. 178. Is probably a variety of Venus puerpera. 
342. 179- Solen bullatus. 
343. 180. Schroeters Cardium No. 20. which is the Cardium flexuosum of Gmelin, has been 
wholly constituted from this figure. But though not well executed, it appears
