FERNS OF JAMAICA 39 
parison of his list of ferns with mine shows that he col- 
lected 90 species as compared with my 82 and that he 
gathered 43 not found by me, while I gathered 35 not 
found by him. Species common to both lists number 
47. 
In conclusion I wish to express my very great thanks 
to Mr. William Harris, Director of the Public Gardens 
of Jamaica, for his kindness in permitting me to stay 
at Cinchona and for the very «valuable aid which he 
rendered me in many ways, and to Mr. W. R. Maxon, 
of the United States National Museum, for making the 
determinations of the ferns.
