My dear Mr. Powell: 
I have reaohed home at last. I take this oppor¬ 
tunity to enclose check for three hundred and fifty dollars on 
account of our field-work program. Perhaps you will let me know 
how far this carries us and inform me of any let up that may come 
as a result of weather conditions. 
It is needless to tell you that I am overwhelmed 
with work and that I see no end to what I have to do. On my return 
to Boston I found over one hundred Lankoster specimens sent for 
determination by Kew. This forenoon about seventy specimens came 
from lankester directly here. I am already pushing ahead with the 
manuscript for Sched. Oreh. 4. I hope to get this out in time to 
avoid the confusion which Soheleohter*s proposed paper on his Costa 
Bican orchids would be apt to create if he antedates me. In Ian- 
kester's sets I have found some good things: one new genus I think 
which I am naming in honor of Lankester. I am still working at 
this. 
Perhaps you think I have neglected C.T7.P. But that 
is not so. I have identified most of your Garden material and the 
new things will appear in Sched. Oroh. 4. Here is a list. 
267 Qnoidium oonfusum Reichb.f. tentative determination. 
268 Masdevallia attenuata Reichb.f. 
269 Bulbophyllum vinosum Schltr.

273 Masdevallia panamensis {Schltr.) Ames n. comb. 
278 Cryptophoranthus Powelii Ames sp, nov.
