The basalt from Kambara resembles a basalt from Kilauea, Hawaii, 

 described by J. D. Dana in the American Journal of Science, (3) 

 volume 18, page 134, (1879). 



Moala. 



Olivine basalt. The writer did not visit the island of Moala but 

 Dr. St. Johnston of Loma Loma kindly presented a few specimens. 

 They are all typical olivine basalts, differing only in structure. 



V. Rocks from Kandavu. 



All the specimens from Kandavu were collected during a rapid 

 survey of the southern coast of the island, east of Vunisea. A large 

 number of villages were visited. Most of them are situated on spur 

 hills, 60 to 75 feet high, along the coast. Usually these hills were 

 deeply lateritized and the specimens were collected from residual 

 boulders, lying on the surface. 



1) Trachytoid Andesite. The specimen was collected from a resi- 

 dual boulder on a lateritized hill, 75 feet high, near the village of Na 

 Vora. 



The rock is light yellowish gray, holocrystallinc and fine-grained. 

 It is nearly devoid of femic minerals. A few small phenocrysts of
