CONCHOLOGY 



naked or shell-less Ascidia, occur we find in^a distant class among ano- 

 ther tribe of animals, Mollusques Brachopodes^ the genus Terebratula, 

 It is here ascribed to Bruguiere, as in other works it is assigned 

 to Lamarck. Such is the arrangement of this family in the Regne 

 Animal of Cuvier, a form in which no cabinet, it must be acknow- 

 ledged, could be arranged without embracing the most unprecedented 

 anomalies ; nor can we doubt that if the animals of the fossil Tere- 

 bratulae and Anomias were known, for in this arrangement they rest 

 on presumption only, they must be further separated in such a 

 system than they are at present, some being perforated at the beaks, 

 others imperforate, and some having the aperture under the beaks, 

 all which demonstrates a difference in the structure of the animal, to 

 whose use they were adapted. 



From this analysis of the generical distinctions of the different 

 families of the Anomiae we may now be permitted to return to the 

 shell before us, the object of our more immediate consideration, and 

 respecting which there appears to be no less misconception among late 

 later writers than we have found already respecting the genera. 



It appears that Dr. Leach had some short time since published 

 a figure of this shell : his definition is altogether brief, and the infor- 

 mation he affords less explanatory than might be desired : he quotes 

 no authority or synonyms, and in his general description merely 

 observes that "It seems to be a very rare species, a few specimens 

 only having been received from New Zealand." Vide. ZooL Misc. p. 76. 

 Lamarck assuming from these observations, as it may be presumed, 

 that the shell had not been previously noticed, unless it were an Ano- 

 mia Capensis of Gmelin, proposes it as a new species under the name 

 of Terebratula Sanguinea of Leach, at the same time that he rejects
