384 FAUNA HAWAIIENSIS 



(2) Opeas prestoni Sykes. 



Opeas prestoni Sykes, P. Make. Soc. London, in. (1898), p. "] i, pi. v. fig. 4. 



A long series, which 1 am entirely unable to sever from the shell recently 

 described by me from Ceylon. The whole genus, however, is notorious for having 

 been discovered in widely separated localities, and probably this species has been 

 transported with plants. 



Hab. Hawaii, Kawailoa, Mauna Loa at 1500 feet (Perkins). 



(3) Opeas pyrgiscus Pfeiffer. 



Bulimus Pyrgiscus Pfeiffer, P. Zool. Soc. London, 1861, p. 24; Malak. Blatt. 



1861, p. 15; Novit. Conch, iii. p. 425, pi. xcvi. figs. 10 — 12. 

 This form does not seem to have been found in recent years. 



Hab. Hawaiian Islands (Pfeiffer). 



Opeas striolata Pease, is recorded as Hawaiian by Nevill (Handlist Ind. Mus. 

 pt. I. 1878, p. 166) ; it appears to be a manuscript name only. 



Caecilioides (Blainville) Herrmannsen. 



(i) Caecilioides baldwini Ancey. 



Caecilianella baldwini Ancey, Mem. Soc. Zool. F" ranee, v. (1892), p. 718. 

 I have followed Mr Smith (J. Conch, vi. pp. 341 — 342) as to the generic name. 

 Hab. Oahu, Manoa (Ancey). 



Fam. SUCCINEIDAE. 



SucciNEA Draparnaud. 



Succinea Draparnaud, Tabl. des Moll. 1801, p. 55 (first species S. amphibia Drap.). 



The large number of unfigured species described from the Hawaiian Islands 

 renders the identification of specimens belonging to this puzzling group by no means 

 an easy task. 



Pease proposed (J. Conchyl. xviii. 1870, p. 89) the genus Catinella for Succinea 

 rubida\ also the genus Truella (P. Zool. Soc. London, 187 1, p. 459) for 5. elongata. 

 I have thought it best to leave all the forms in Succinea, and have listed the species in 

 alphabetical order.
