398 FAUNA HAWAIIENSIS 
Fam. NERITIDAE. 
NeErRITINA Lamarck. 
I have not seen the first Edition of the ‘ Philosophie Zoologique’ (1809) in which 
this genus is said to occur, but in the second edition (1830) the name appears in French 
only, with no diagnosis or named species (Vol. 1. p. 321). However in his ‘ Hist. An. 
sans Vert.’ it is duly given in Latin with named species (Vol. vi. pt. 2, p. 182). 
The first is WM. ferversa Gmel., which is the type of Montfort’s Vedates (1810) 
under the more correct name of V. conozdea, but the others belong to Mevitina as 
we understand it to-day. 
(1) Nerttina cariosa Gray. 
Nerita cariosa Gray, Wood, Index Test. Suppl. Verzta fig. 9 (1828). 
Neritina sandwichensts Deshayes, An. sans Vert. Ed. 2, vii. (1838), p. 579. 
Neritina convexa Nuttall, Jay, Cat. Shells, Ed. 3, 1839, p. 66 (nom. sol.). 
Neritina nuttalli Recluz, Rev. Zool. 1841, p. 276; Souleyet, Voy. Bonite, Zool. 11. 
pl. xxxiv. figs. 43—46. 
Neritina solidissima Sowerby, Thes. Conch. 1. p. 541, pl. cxvi. fig. 573. 
I have not sufficient material to determine whether the large synonymy given by 
Tryon (Man. Conch. x.) is fully justified. Prof. von Martens (Conch.-Cab. Neritina) 
expressed the opinion (p. 276) that Merzé7na cariosa Gray does not really belong here, 
but is a form of MV. mauritzz: this has been dealt with by Mr Smith (P. Zool. Soc. 
London, 1884, p. 275). 
Has. Hawaiian Islands (various authors).—Maui and Oahu (Baldwin).— Hawaii, 
Hilo (Smith). j 
(2) Neritena granosa Sowerby. 
Neritina granosa Sowerby, Tank. Cat. App. p. x1. (1825); Conch. Ill. Merztina 
fig. 6. 
Neritina papillosa Jay, Cat. Shells, Ed. 2, 1839, pl. 1v. fig. 11. 
Neripteron gigas Lesson, Rev. Zool. 1842, p. 187. 
Has. All the Islands (Baldwin).—Molokai, Pelekunu (Perkins). 
(3) Neretena lugubris Philippi. 
Neritina lugubris Philippi, Abbild. Conchylien, 1. pt. 2, p. 20, pl. 1. fig. g (1845). 
This has been placed as a synonym of JV. cariosa, but from the description and 
figure it seems to be distinct. 
Has. Hawaiian Islands (Philippi).
