396 FAUNA HAWAIIENSIS 
Fan, PALO DEST RIN TDA: 
PaLupestrina D’Orbigny. 
Paludestrina porrecta Mighels. 
Paludina porrecta Mighels, P. Boston Soc. 11. (1845), p. 22. 
Has. Oahu (Mighels). 
Pam. HELICINIDAE: 
Heticina Lamarck. 
In 1799 (Mém. Soc. Hist. Nat. Paris, p. 77) the genus was described but no type 
or species named; in 1801 (Syst. An. sans Vert. p. 94) the only species named was 
Helicina neritella Lam., which may be taken as the type. Lamarck refers for a figure 
to Lister (Hist. Conch. fig. 59), and this illustration appears to represent a //edczna, 
though it is hard to be certain whether it be 77. xerztedla or not. 
(1) Helicina lacinzosa Mighels. 
FHelicina laciniosa Mighels, P. Boston Soc. 1. (1845), p. 19; Gould, U.S. Explor. 
Exped. Moll. pl. vu. fig. 108. 
A very variable shell in size and coloration; it appears to be always more 
compact and elevated than /7. sandwichiensts. 
Has. Oahu (Mighels).— Kauai (Baldwin).—Lanai, behind Koele; also Kalamaula, 
Molokai; Kaala, Oahu; and between Lihue and the sea, Kauai (Perkins). 
(2) Helicina magdalenae Ancey. 
Flelicina magdalenae Ancey, Bull. Soc. Malac. France, vit. (1890), p. 342. 
Flelicina constricta Pfeiffer, P. Zool. Soc. London, 1848, p. 120; Conch.-Cab. 
Ftelicina, p. 22, pl. vu. fig. 37—9 [both relate to his variety only]. 
Pfeiffer’s typical form came from ‘Otaheite’ and appears to belong to a different 
species to his variety, which seems to be identical with this. Possibly forms may be 
found linking 7. magdalenae to H. uberta. 
Has. Oahu, Tantalus (Ancey).
