Fossil Terebratulse. 439 



bra tula impressa. The description however cannot have been 

 drawn up from that shell, or Lamarck would not have stated it 

 to be white. I have given the figure of the Terebratula impressa 

 marked Ter. concava from B. Delessert's collection, as well as a 

 figure of Mag as pumilus from Meudon marked fig. M. It is 

 therefore evident that Lamarck's species must be cancelled from 

 the nomenclature. 



27. Terebratula semiglobosa (Sow. M. C. tab. 15. fig. 9). 

 Obs. Lamarck does not seem to have known Sowerby's spe- 

 cies, as none of the three specimens marked such in B. Delessert's 

 collection belong to it, being specimens of Ter. ornithocephala, 

 and a variety of Ter. globata, Sow. The true species is cretaceous. 



28. Terebratula punctata (Sow. M. C. pi. 15. fig. 4). 



Obs. Several specimens are to be seen in M. Delessert's col- 

 lection, none of which are Sowerby's type : Lamarck's speci- 

 mens belong to Ter. numismalis, indentata and vulgaris. Sowerby's 

 species is a well-characterized liasic shell. 



29. Terebratula phaseolina, Val. in Lamk. PL XIII. fig. 29. 



T. testa parva, subcompressa, rotunda, alba, striis concentricis, mar- 

 gine supero sub-biplicato : nate brevi, non producta. 

 Obs. M. D'Orbigny seems to consider Lamarck's Terebratula 

 phaseolina to be Brocchi' s Anomya biplicata, Pal. Franc. Ter. Cre- 

 taces, vol. iv. p. 95. pi. 511. fig. 9, 15. After comparing the 

 numerous specimens of Ter. phaseolina in M. le B. Delessert's 

 collection with the figures given by Brocchi, l Conchologia Fos- 

 sile,' p. 469. pi. 10. fig. 8, 1814, I cannot believe them to be the 

 same shell as Ter. phaseolina ; and since even M. D'Orbigny places 

 a point of interrogation behind his synonym of Brocchi, it is evi- 

 dent he was not certain of the identity. I therefore do not see 

 why Lamarck's well-known species should make place for Broc- 

 chi' s uncertain one ; which has no indication of locality or de- 

 posit. It seems also strange that M. D'Orbigny should every- 

 where write Lamarck's Ter. phaseolina, "phaseolina " and whilst 

 he rejects it in page 95, adopts it in page 109 of the f Pal. Franc. 

 Ter. Cretaces.' 



30. Terebratula ovata (Sow. M. C. pi. 15. fig. 3). 



Obs. As M. Deshayes observes, in his new ed. of Lamarck, 

 the specimens in the museum of the Garden of Plants do not 

 belong to Sowerby's type. M. Deshayes believes them to re- 

 semble Ter. lata of Sow., but they do not represent that species. 



31. Terebratula biplicata (Sow. M. C. pi. 90. fig. 1, 5). 

 Obs. We find a number of specimens under this name in La-
