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. Nove-Zelandia, p. 2, t. 9, 
f. 54... A. agglutinans, p. 2, t. 10, f. 19. 
On CrLavaGELLA (p. 2). See, likewise, C. rapa (Rang. Man. Mol.), 
C. Sicula and C.? angulata (Phil. Sic. vol. 2). 
O-aperta. pa2, t.O2 t.2'....C. elongata, p. 2. t. Li, fU; 20k 
C. lata, p.2, t 11, f.4... C. Melitensis, p. 2, t.11, f.3... C. Australis, 
p- 2, t. 9, f. 22 ... C. Balanorum, p. 2, t. 10, f. 21. 
On Fistutana. Not one of the specific names used by Lamarck 
can be retained. Spengler had previously described clava as Gastro- 
chena mumia in 1783, gregata (subsequent to Gmelin’s name 
T. clava) as Teredo nucivorus in 1791 (published in 1792), and 
lagenula (in 17838) as G. cymbium. 
F’. mumia (as clava, p. 8, t. 11, f. 5)... F. cymbium (as lagenula, 
Pues t..19, f. 59). 
On Trrepo. 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 J. Philippii has been proposed for the T. navalis of 
Philippi (note, p. 3), ZT. denticulata for the T. navalis of Moller 
(Grenl. Mol.) and 7. Stutchburii for the 7. navalis of Spengler 
(Skriv. Nat.). According to Petit the 7’. corniformis (p. 4) 1s only 
the tube of our JT. 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 7’. 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...
