On a Collection of Ferns made by the Rev. R. B. Comins in the 
Solomon Islands. By J. G. Baxter, F.R.S., PLS 
[Read June 15, 1882.] 
I nave just been favoured with an opportunity of examining a 
collection of ferns made by the Rev. R. B. Comins in the Solomon 
Archipelago, collected mainly in San Cristoval, the southern 
island of the group, and the adjacent islet of Contrarietes. It 
contains altogether upwards of sixty species of ferns, Lycopods, 
and Selaginellace&, of which the following are of special interest, 
the remainder being widely-spread Polynesian and tropical 
Asiatic types.
