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 lotopkaga. 

 Subg. PETRIOLA Dall, type marmorea. 



ACHATINA LEUCOSTYLA 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, ventrieose, 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. 



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

 synonyms : Bidimus 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.
