Rough and unscientific as they avowedly are, I am assured 

 that my diagnostical keys to the Osmotrerons, Arboricolas, 

 Arachnotheras Black-naped Orioles, &c., have proved most ser- 

 viceable to field naturalists here, and I propose, to publish a 

 number more of these, embracing Tits, Goatsuckers, Phylloscopi, 

 Reguloides, Abrornis and the like troublesome genera. I would 

 earnestly solicit contributions of this nature from all who have 

 made any such groups their especial study. 



In conclusion, I would again invite all sportsmen (even though 

 no ornithologists, to favor me with notes of their experiences 

 as to the habits, habitats, food and nidification of game and 

 other birds that they shoot ; about which, as is only natural, 

 they often possess more real knowledge, than the great majority 

 of professed ornithologists.
