APPENDIX. 



TRICHODINA Ancey (p. 182). 



Dall has shown that this name is preoccupied. It was used 

 by Ehrenberg in 1830 for an infusorian (not a foraminifer, 

 as he states). He therefore proposes to substitute the term 

 Petriola (Nautilus, xviii, April, 1905, p. 143). This necessi- 

 tates a change in the arrangement of my text. The groups 

 should stand thus: 



Genus BOCAGEIA Girard (p. 191), type lotophaga. 

 Subg. PETRIOLA Dall, type marmorea. 



ACHATINA LEU COST YL A Pils. Page 45. 



This form proves to be so different in genitalia from A. 

 panthera that it will stand as a species. See anatomical notes 

 in introductory pages of this volume. 



Achatina (Liguus) unizonata Cristofori et Jan. Shell 

 conic-ovate, ventricose, smooth, whitish, zoned with a brown 

 line ; interior margin of the columellar lip white, outer brown. 

 1 inch 10 lines high, 1 inch wide, aperture 11 lines long, 6 

 wide. South America. (Catalogus, etc., sect, ii, part 1, p. 4; 

 Mantissa, p. 2, no. 7-4. 1832). 



Probably a synonym of Liguus fasciatus. 



Chersina imperialis Beck, Index Moll., p. 74. "Afr. oc." 

 Nude name = Pseudotrochus. 



Achatina serpentina Beck, Index Moll., p. 76. Afric. 

 occid.(?). Nude name. 



Atopocochlis exarata (Mull.). Vol. xvi, p. 218. Add the 

 synonyms: Bulimus crystallinus Greef, Zool. Anzeiger, 1882, 

 p. 520, and Pseudachatina vitrea Greef, Sitzungsber. Ges. zu 

 Marburg, 1884, p. 51. See Jornal de Cien. Math., Phys. e 

 Nat. Lisboa, iii, 1893, p. 38.
