Hab. Pasaguing, province of North Ylocos, island of Lucon: on 
stones in a small river. 
The operculum of this species does not differ from that of N. pul- 
ligera, except in its colour, which is of a brownish black, faintly and 
indistinctly striated with fawn-colour from the summit to the anterior 
margin ; the striz often scarcely apparent.

Hab. Jimmaymilan, isle of Negros: found on the trunks of the 
Nepa Palm, in brackish water. 
I do not see in the characters of this Nerite anything to cause its 
separation from the Neritina crepidularia, Lam. ; N. mitrula, Menke, 
‘Synopsis,’ p. 48; nor from the N. violacea, Gmelin, if it is not its 
larger proportions. I presume that the Patella neritoidea, Linn., 
Mus. Lud. Ulr., p. 688. No. 409, is the same shell, worn and occu- 
pied by a Pagurus.
