No. 17. — On the identity of Ennea (Gulella) pallaryi, Preston, 



WITH Ennea vriesiana, Ancey. 

 A COMPARISON of co-types of Ennea pallaryi, Preston (Ann. & Mag. 

 Nat. Hist., 1909, vol. iv, p. 87) with specimens that I believe are 

 authentic of Ennea vriesiana, Ancey (Bull. Soc. malac. France, 

 1885, p. 145) demonstrates their identity. 



No 18. — Xestina granulosa. MoUdfi., a synonym of Helix 



DAN^, Pfr. 



1862. Helix dance, Pf., Proc. Zool. Soc. Lond., p. 268. 



1902. Xestina granulosa, Molldfi., Nachr. Bl. Deutsch. Malak. 

 Gesell., p. 156. 



Comparison of original specimens of Xestina granulosa, MoUdfi., 

 with the type-specimen in British Museum of Helix dana^, Pf., proves 

 that they are one species. The type of dance is slightly flatter, 

 but agrees in all other respects with granulosa. 



No. 19. — On the identity of Bulimulus (Drym^eus) 

 pulcherrimus, Ad., with subhybridus, Da Costa. 

 1866. Otostomus pulcherrimus, H. Ad., Proc. Zool. Soc. Lond., 



p. 442, pi. 38, fig. 3. 

 1906. Gonostomus subhybridus, Da Costa, Proc. Malac. Soc. Lond., 



vol. viii, p. 97, pi. xi, fig. 7. 

 A fine specimen of Dryymeus pulcherrimus from Huancabamba, 

 Peru, having been compared with the type-specimen of subhybridus, 

 has revealed their identity. The specimen of pulcherrimus was in 

 the collection of the late J. J MacAndrew, Esq., with another 

 specimen, a variety with white peristome and purple aperture, 

 but otherwise agreeing, perfectly with typical pulcherrimus. 



No. 20. — On Pseudachatina perelongata, Eolle, and P. 

 daillyana, Pilsbry. 



1902. Pseudachatina perelongata, Rolle, Nachr. Bl. Deutsch. 



Malak. Gesell., xxxiv, p. 211. 



1903. — daillyana, Pilsbry, Tryon's Man. Conch., ser. ii, 



vol. xvi, p. 214. 

 Having examined a specimen of Pseudachatina perelongata, 

 Rolle, supplied by Rolle to the late J. J. MacAndrew, I have no 

 hesitation in pronouncing its identity with P. daillyana, Pilsbry.
