fifth, the furthest of all, say about seven miles comparing with 
about two and one-half miles, locality one. 
The fossils were found lower than the live specimens on the 
ridges, and as we go east the live specimens are found higher 
up on the ridges or further away from the lower limits as indi- 
cated by the fossils.

were found by A. Gouveia buried about four feet deep in Manoa 
valley near Manoa tennis court. The montaguei is now extinct 
and the buddi nearly so in other localities. They are however 
extinct in the above given locality. These shells thrived very 
low once, and owing to the climatic changes the forest has dis- 
appeared, thus explaining the present distribution. 
The strongest evidence yet is indicated by fossil ground shells, 
catalogue numbers 932 to 942 inclusive, Leptachatina oryza and 
a few. other unnamed varieties which were collected on the 
western slope of Diamond Head, also catalogue Nos. 859 to 
869 inclusive. Amastra transversalis also Endodonta and Lepta- 
chatina, Nos. 972 to 975 inclusive, collected on the town side of
