32 Ridgway on Birds new to the Fauna of Illinois. 
The six species enumerated above reduce the number of “proba- 
bilities ” given by me (in 1874) in my “ List of Birds ascertained to 
occur in Illinois,” from 43 to 28, or more than one third, the sub- 
sequent additions including several species not included among the 
species given as likely to occur, e. g. Dichromanassa rufa, Platalea 
ajaja , and Pelecanus fuscus. A thorough exploration of the swampy 
country in the vicinity of Cairo would no doubt result in the addi- 
tion of other Southern species, perhaps some hardly to be thought 
of as occurring so far north. Of the 28 species still remaining in 
the list of species u to be looked for,” Helinaia swainsoni very prob- 
ably occurs (see this Bulletin, Yol. Ill, p. 163). 
Mr. W orthen has favored me with interesting notes on several 
other of the rarer or more interesting species of Illinois, wdiich, with 
his permission, I take pleasure in recording here : — - 
Coturniculus lecontei. Leconte’s Bunting. — “I have taken in 
the last two years, on the prairies here, some twenty specimens ; have taken 
them both in fall and spring, as well as during the summer, and am satis- 
fied they breed here, though I have not been able to find their nests or 
eggs. I have found them on low swampy prairies in the Mississippi bot- 
toms, and on dry prairies on the bluffs ; but generally in swampy or marshy 
ground.” 
Ammodromus caudacutus nelsoni. Nelson’s Sharp-tailed 
Finch. — “Took a beautiful adult male, May 8, 1879 ; flushed him from a 
timothy meadow. The only one I have seen here.” 
Elanoides forficatus. Swallow-tailed Kite. — “Saw one speci- 
men flying last summer, and one this year, but did not succeed in getting 
either.” 
Protonotaria citrea and Oporornis formosa. — The Profhonotary 
and Kentucky Warblers are so numerous that Mr. W. takes “ from fifty 
to a hundred each season.” 
Ibis alba. White Ibis. — “I had a full account in my lost field-notes 
of one of these birds being taken in the southern part of the State.” This 
species was observed by the writer in the spring of 1878, at Mount Car- 
mel, but no specimen obtained (see this Bulletin, Yol. Ill, p. 166). 
Larus franklini. Franklin’s Rosy Gull. — “ There is a beautiful 
adult male of this species mounted in the State Museum at Springfield, 
which I took in May, 1875. It was flying over a pond in the Mississippi 
bottom, three miles below here.”
