347a. Telmatodytes palustris iliacus (Ridgway). 

 Prairie Long-billed Marsh Wren. 



Distr.: Prairie districts of central United States, east to Illinois 

 and western Indiana and north to the British Provinces; winters 

 chiefly in the Gulf states and Mexico; breeds throughout its summer 

 range. 



The Prairie Long-billed Marsh Wren differs from the eastern form 

 in being generally slightly larger, and having the upper parts more 

 russet brown and the flanks clear cinnamon buff, approaching a 

 russet tint more than in T . palustris. 



The nest and eggs are similar to those of T. palustris. By cour- 

 tesy of the authorities of the United States National Museum, I have 

 been able to examine the type of T. p. iliacus * and compare it with 

 specimens in the Field Museum collection. The result shows that 

 both T. palustris and T. p. iliacus occur in Illinois. Specimens in 

 the collections of the Field Museum of Natural History from Illinois 

 and Indiana are as follows: 



No. 5150, 9, May 24, 1890, Ravinia, 111. 



No. 5151, d^, May 29, 1894, Englewood, 111. 



No. 5415, d^, May 31, 1885, Davis, Stark Co., Ind. 



No. 30408, ^ , June 7, 1905, Fox Lake, 111. 



No. 30409, fj^, June 7, 1905, Fox Lake, 111. 



I have not seen specimens from Wisconsin, but it no doubt occurs 

 there, especially in the western portion of the state.
