1880. Lanepon, F. W. Summer Birds of a Northern Ohio Marsh. 
By Frank W. Langdon. < Jour, Cin. Soc. Nat. Hist., vol. 
iii., 1880, pp. 220-232. 
A list of 95 species, for the most part briefly annotated or not, of birds 
observed ‘on the grounds of the Wynous’ Point Shooting Club, near Port 
Clinton, Ottawa county, Ohio, during the week ending July 4, 1880.” 
Full notes of the nesting of Ardetta evilis, Gallinula galeata, Hydrochelidon 
lariformis, Podiceps cornutus (?) and Podilymbus podiceps. 
1880. Ripeway, Rozgert. Note on Helminthophaga cincinnatiensis, 
Langdon. < Bulletin Nuttall Ornith. Club, vol. v., No. 4, 
Oct., 1880, pp. 237-238. 
A critical note, questioning its validity as a species, and suggesting the 
possibility or probability of its being a hybrid between Helminthophaga 
pinus and Oporornis formosus. A further study of the specimen in ques- 
tion has caused Mr. Ridgway to modify considerably his opinion above 
cited, and he ranks it as a species in his Nomenclature of North American 
Birds, of 1881, but still suggests that it ‘‘may be” a hybrid. As Dr. Coues 
himself asked the privilege of describing it as a species, and of naming it 
after its discoverer, its validity may be considered as at least probable. 
1881. Beckuam, C. W. Peucza estivalis illinoisensis, Ridgway. 
<Journal Cin. Soc. Nat. Hist., vol. iv., pp. 339-340.

Herrick ; with some conjectures respecting certain other North 
American Birds. < Bulletin Nuttall Orn. Club, vol. vi., No. 
4, Oct., 1881, pp. 218-225. 
Advances the hypothesis that the above-named species are hybrids be- 
tween H. pinus and H. chrysoptera, and sustains it by quoting in a foot- 
note to page 224, Mr. Ridgway’s supposition in regard to the hybridity of 
Helminthophaga cincinnatiensis.
