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, c?, June 7, 1905, Fox Lake, 111. 



No. 30409, c?, June 7, 1905, Fox Lake, III. 



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

 there, especially in the western portion of the state.
