CONCHOLOGY. 



in which he does not speak of himself as having invented that term. 

 " Terebratulas, Luidiano titulo, vocamus DiACONCHAS ano- 

 malas, rostro parterebrato, vid. NomencL Litholog. Promotum hoc 

 titulo." His genus Concha tpi'aobos, genus Concha Adunc A, genus 

 BuRSULA, and genus Globus, are all sub-divisions of the Anorniae 

 Conchce of other writers, divided according to their forms and other 

 peculiarities, and in which particular attention is paid to the perforation 

 or non-perforation of the beak; Trilobos being distinguished as 

 ^'vertice integro,^ Bursula as Terchratuloe formes rostro non perforate, 

 &cT And we may lastly mention that from some original MSS. of 

 Da Costa, in our possession, it appears that Anomia was a general term 

 for the whole family, and Terehratula Anomice ice vis was the term by 

 which the English and other Naturalists, long prior to the middle of 

 last century, were acustomed to distinguish the same kind of shells 

 which in the modern nomenclature of Conchology is also named 

 generically Terehratula. Da Costa, as Librarian of the Royal Society, 

 was in the habit of correspondence with the learned men of his time 

 throughout Europe, and his local knowledge from this circumstance, 

 though never committed to the press, is not hkely to be disputed. 



We could proceed yet further, but enough has surely been 

 advanced to shew that so far from Linnasus having confounded the 

 Terehratula v^^ith the Anomia, he left them precisely as he found 

 them, placing them after the example of his predecessors, under the 

 comprehensive term of Anomia, which they had assigned to them. 

 And we have also said enough to prove that to ascribe the Genus 

 Terehratula to either Bruguire or Lamarck can result only from our 

 ignorance of that information which in former days was regarded as 

 the best criterion of an able Naturalist, a correct knowledge of the 

 labours of his predecessors.
