AAA. Mr. T. Davidson on Lamarck’s species of 
Obs. Lamarck refers to pl. 245. fig. 2 a, b. of the ‘ Ency. Mé- 
thod., but as M. Deshayes justly observes in his new edition of 
Lamarck, this species is the same as that published in 1814 by 
Brocchi under the name of Anomya Vespertilio, Conchologia Fos- 
sile, fig. 17, which is also evident from specimens both in the 
collection of the Garden of Plants and of B. Delessert’s museum. 
M. Deshayes also remarks, that on looking at the figures 1 and 2 
of the pl. 245, one would have some difficulty in believing that 
both belonged to the same species: I agree with M. Deshayes 
in this—fig. 1 would agree with Brocchi’s type and Lamarck’s 
specimens. This species varies much, as can be well seen in 
M. D’Orbigny’s figures, Pal. Frang. vol. iv. pl. 499. fig. 1-7. 
Fig. 2. pl. 245, the one referred to by Lamarck, is probably Tere- 
bratula compressa, Lamk. no. 54, as it shows that peculiarly 
shaped front so well displayed in this shell; however there are 
more than one species placed under this head in the Paris col- 
lections. At the Garden of Plants we find on the same tablet a 
specimen of Terebratula Vespertilio associated with Ter. latissima 
of Sowerby, and at M. Delessert’s we see three or four species, 
among which, under the head of variety, is placed a specimen of 
Pentamerus, a Spirifer, and a Terebratula of quite another shape. 
This association is so strange that I can hardly believe they were 
so put together by Lamarck. Brocchi’s name however should be 
preserved to this species, and that of Lamarck placed among the 
synonyms. The identity of Lamarck’s species with that of 
Brocchi is also admitted by M. D’Orbigny in his ‘ Pal. Frangaise 
Ter. Crétacés,’ vol. iv. p. 44. ; 
44, Terebratula concinna (Sow. M.C. tab. 83. fig. 6). 
Obs. The specimens under this name in B. Delessert’s collec- 
tion appear to belong to Ter. obsoleta, Sow. 
45. Terebratula media (Sow. M. C. tab. 83. fig. 5). 
Obs. The specimens ticketed thus by Lamarck belong to 
Sowerby’s true Ter. tetraédra: the distinctions between Ter. te- 
traédra and media, Sow., are very trifling. 
46. Terebratula pectita (Sow. M. C. tab. 188. fig. 1). 
Obs. I did not find any specimens of this species in either of 
Lamarck’s collections. 
47. Terebratula Cardium, Val. im Lamk. Pl. XIV. fig. 47. 
T.. testa elongato-ovata, convexa, plicata, sulcis longitudinalibus crassis, 
rotundatis : nate prominula. 
Var. b. testa compressiuscula, sulcis crebrioribus. 
Obs. Lamarck refers to pl. 241. fig. 6a, b, c. of the ‘ Ency. 
Méthod.,’ and this species is too well known to require many re-
