Dear Doctor Robinson: 
I an sending you, in 5 packages, by mail, the ferns 
of the collection made in Jamaica by Mr. Kill ip aijd myself, 
and herewith typewritten list of identif icationl A «¥ locali- 
ties for the same. The identifications are in general de- 
pendable, I think, but there are two or three 3pecies of 
Pol vp odium and several of the Hymenophyllaceae which will 
have to be worked out critically at a later • time. 
The phanerogams of the collection, with a similar list 
of identifications and localities, will be forwarded within 
a short time; but it will probably not be possible^ to send 
the cryptogams before autumn, inasmuch as these will have to 
await determination by several specialists. 
Hoping that the material will reach you in good 
condition, I am, 
Youn 
William R. Maxon
