THE NERITINA OF HAWAII 
There are three species of Neritina found on the island of 
Hawaii : A^. granosa Sby, N. cariosa Gray, and A^". tahitensis Less. 
(N. vespertina Meth.). 
A'^. granosa lives entirely in fresh water. It can be collected in 
almost all of the numerous streams of the windward coast. It is not 
very variable. It lives on smooth stones, generally in colonies. In 
swift water the shells have no moss upon them, but in calm, deeper 
water they are nearly always coated with a growth of green algae. I 
have collected them by diving for them in as much as ten feet of 
water, although most of them are found near the five foot level. 
A^. cariosa is distinctly an inhabitant of brackish water. I have 
collected it in a few localities with A^. tahitensis, but never with A^. 
granosa. It is very plentiful in isolated ponds of brackish water 
along the coast. Like A^. tahitensis it is often much corroded, while 
N. granosa is never corroded in the least. 
A^. tahitensis is more limited in the number of localities in which 
it is found than the other two. I have collected it with both the other 
species. It is most plentiful in a large pond of fresh water where 
it grows to perfection on the under surfaces of loose rocks. They 
immediately release their hold upon a rock when it is removed, but 
the other two species, especially A^. cariosa, stick very tightly to the 
object they are upon. 
The Hawaiians use all three species for food, boiling them and 
eating them with salt. I once sampled a Neritina granosa, but found 
it very unpalatable. The:odore: Dranga, 
Hilo, Hawaii.
