22 INDEX TO THE HISTORIA CONCHYLIORUM. 
Tab. Fig. 
stituted, but the Tellina triangularis of Chemnitz is quite different: this has 
more of the appearance of a Mactra. 
401. 245. Is probably a worn shell of Mactra striata. 
402. 246. V i emis litterata. 
403. 247. Venus virginea. 
404. 248. Quoted erroneously in the Descriptive Catalogue for Venus virginea, and is Ve¬ 
nus geographica; which Dr. Turton considers to be of the same species as Venus 
aurea, but it is constantly much more oblong. 
— 249. Venus aurea; and the name was originally given by Gmelin to a description of 
this figure. 
405. 250. Tellina zonata. 
— 251. Tellina Balaustina. 
406. 252. Tellina angulata. 
407. 253. From this figure the Tellina No. 43. of Sehroeters Einleitung, and the Tellina 
lata of Gmelin, have been constituted; and Meuschen, in the Museum Gever- 
sianum, has quoted it for another uncertain species, with the name of Tellina 
Nucleus-Acacias. 
408. 254. The Tellina No. 44. of Schroeter, which is the Tellina Jamaicensis of Gmelin, has 
been wholly derived from this figure; and I rather doubt whether it is more 
than a variety of Tellina fragilis. 
409. 255. Solen Siliqua; and this figure is taken from the Historia Animalium Angi ite, t. 5. 
f.37. 
410. 25 6 . Solen Vagina. 
411. 257. Solen Ensis; and it is taken from the Appendix to the Historia Animalium 
Anglite, t. 2. f. 9. 
412. upper fig. Solen Siliqua, with the animal. 
— lower fig. Solen truncatus: and in the Portland Catalogue, lot 1005, this figure has 
been quoted for the Solen pallidus of Solander, which is the same species. 
413. upper fig. Variety of Solen Vagina. 
— lower fig. Full grown shell of Solen Ensis. 
414. 258. Mya Glycy meris. 
415. 259. Mactra lutraria. 
416. 260. Solen strigilatus. 
417. 261, Tellina albida. 
418. 262.) n/r 
f Mna arenaria. 
419. 263.) ^ 
420. 264. Solen Legumen. 
421. 265. The species to which this figure belongs has been generally confounded with 
Solen strigilatus, but is perfectly distinet, and is the Solen plebeius of Solander, 
and the Solen Caribceus of Lamarck. Dr. Turton has also quoted this figure for 
a shell which has been picked up in the Scilly islands, and to which he has 
given the name of Psammobia declivis. 
422. 266. Solen radiatus. 
423. 271. Is obviously Venus decussata; and yet the Venus fusca and the Venus obscura of 
Gmelin have both been constituted cntirely from this figure. 
424. 272. Dr. Solander considered this figure, from which the Venus No. 80. of Schroeter, 
and the Venus purpurata of Gmelin have been constituted, to be only an acci- 
dentally deformed shell of Venus deflorata. 
425. 273. Venus deflorata. 
426. 267. Solen minutus. 
427. 268. Mytilus lithophagus. 
428. 269. Mya truncata. 
429. 270. Variety of Mya truncata.
