Species of AMPTJLLAE-IA. (sensu stricto). 



1. Ampullakia Amazonica, Reeve. 

 Conch. Icon., sp. 55. 



Sai. — River Amazon. 



This is allied to haustnim and ffiffas, but its suture, though depressed, 

 is not deeply channelled, as in those species. 



2. Ampullaria Aitlanieri, Hupe. 

 Voy. de Castelnau, 1847. 



Sab. — Peru. 



3. Ampullaria auriformis. Reeve. 

 Conch. Icon., sp. 133. 



Sab. — Honduras (Reeve). 



This may possibly be a variety of A. Hbpeionensis, but the effusion 

 of the base of the aperture is remarkable. 



4. Ampullaria avellana, n.sp., p. 360. 

 5. Ampullaria Baeri, Dautzenberg. 

 Journ. de Conch., 1901, vol. xlix, p. 312, pi. ix, figs. 12, 13. 

 Sab. — Rio Mixiollo, Prov. Huallaga, Peru. 



6. Ampullaria Bridgesi, Reeve. 

 Conch. Icon., sp. 50. 



Sab. — Rio Grande, Bolivia. 



7. Ampullaria bulla. Reeve. 

 Conch. Icon., sp. 104. 



Sab. — Mexico. 



8. Ampullaria buxea, Reeve. 

 Conch. Icon., sp. 112. 



Sab. — Jamaica. 



9. Ampullaria cabtaliculata, Lamarck. 

 Anim. sans Vert., 1819, 1st ed., vol. vi, p. 178. 



Sab. — Rivers of Guadeloupe (Lamarck). 



I have not been able to identify this shell. The figure in 

 Delessert's " Receuil," pi. xxxi, fig. 3, is A. gigas, Spix, and cannot 

 be Lamarck's type of canalieulata, which is described as only 25 X 22 

 lines. The shell figured in Reeve's " Conchologia Iconica " for the 

 species is an Eastern form, A. speciosa, Phil., while specimens of 

 A. haustrum and immersa, Reeve, and msularum, D'Orbigny, have 

 done duty for it in various collections.^ 



10. Ampullaria Castelloi, Sowerby. 

 Proc. Malac. Soc, 1894, vol. i, p. 48, pi. iv, fig. 22. 



Sab. — River Meta, S.E. Bogota. 



This species presents considerable variation. The columella of 

 the type is bright red, but in other specimens it is nearly white. 



' Since reading this paper I have identified this species. See note, p. 363.
