398 FAUNA HAWAIIENSIS 



Fam. NERITIUAE. 



Neritina Lamarck. 



I have not seen the first Edition of the ' Philosophic 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. i. 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 N. perversa Gmel., which is the type of Montfort's Velates (1810) 

 under the more correct name of V. conoidea, but the others belong to Neritina as 

 we understand it to-day. 



(i) Neritina cariosa Gray. 



Nerita cariosa Gray, Wood, Inde.x Test. Suppl. Nerita fig. 9 (1828). 



Neritijia sandwickensis Deshayes, An. sans Vert. Ed. 2, viii. (1838), p. 579. 



Neritina convexa Nuttall, Jay, Cat. Shells, Ed. 3, 1839, p. 66 (nom. sol.). 



Neritina mittalU Recluz, Rev. Zool. 1841, p. 276 ; Souleyet, Voy. Bonite, Zool. 11. 

 pi. xxxiv. figs. 43 — 46. 



Neritina solidissima Sowerby, Thes. Conch. 11. p. 541, pi. 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 Neritina cariosa Gray does not really belong here, 

 but is a form of A^. mauritii : this has been dealt with by Mr Smith (P. Zool. Soc. 

 London, 1884, p. 275).

 Neripteron gigas Lesson, Rev. Zool. 1842, p. 187.

(3) Neritina lugubris Philippi. 



Neritina lugubris Philippi, Abbild. Conchylien, i. pt. 2, p. 20, pi. i. fig. 9 (1845). 



This has been placed as a synonym of N. cariosa, but from the description and 

 figure it seems to be distinct. 



Hab. Hawaiian Islands (Philippi).
