APPENDIX, 



CONTAINING DESCRIPTIONS OF THE SHELLS DELINEATED [N THE 



PLATES, YET NOT DESCRIBED IN THE TEXT ', WITH A 



SYSTEMATIC LIST OF THE ENGRAVINGS, ETC. 



On Aspergillum (p. 1). A monograph of this genus has been 

 published in the ' Illustrations Conchyliogiques ' of Chenu. A. dicho- 

 tomum has been misprinted in the note (p. 2). 



A. vaginiferum, p. 1, t. 9, f. 23 ... A. Novce-Zelandice, p. 2, t. 9, 

 f. 54 ... A. agglutinins, p. 2, t. 10, f. 19. 



On Clavagella (p. 2). See, likewise, C. rapa (Rang. Man. Mol.), 

 0. Sicula and C. ? angulata (Phil. Sic. vol. 2). 



C. aperta, p. 2, t. 9, f. 21 ... C. elongata, p. 2, t. 11, f. 1, 2 ... 

 C. lata, p. 2, t 11, f. 4 ... C. Melitensis, p. 2, 1. 11, f. 3 ... C. Australis, 

 p. 2, t. 9, f. 22 ... C. Balanorum, p. 2, t. 10, f. 21. 



On Fistulana. Not one of the specific names used by Lamarck 

 can be retained. Spengler had previously described clava as Gastro- 

 chcena mumia in 1783, gregata (subsequent to Gmelin's name 

 T. clava) as Teredo nucivorus in 1791 (published in 1792), and 

 lagenula (in 1783) as G. cymbium. 



F. mumia (as clava, p. 3, t. 11, f. 5) ... F. cymbium (as lagenula, 

 p, 3, t. 13, f. 59). 



On Teredo. Consult the author's ' British Mollusca' (vol. 1), and 

 Gray's paper in the Annals of Nat. H. 1851 (vol. 8), in which last 

 the name T. Philippii has been proposed for the T. navalis of 

 Philippi (note, p. 3), T. denticulata for the T. navalis of Moller 

 (Graenl. Mol.) and T. Stutchburii for the T. navalis of Spengler 

 (Skriv. Nat.). According to Petit the T. corniformis (p. 4) is only 

 the tube of our T. navalis. The name of the latter (p. 3), which is 

 not strictly the Linnean species, but that received as such by the 

 earlier British conchologists, should be changed to T. Norvagica, 

 Spengler (Skriv. Nat.). See, too, An. Sc. Nat. ser. 3, vol. 3. 



T.palmulata, p. 4, t. 11, f. 13 ... T. bipennata, p. 4, t. 9, f. 50 ...
