DESCRIPTION OF A NEW TELMATODYTES. 



BY HARRY C. OBERHOLSER. 



Two long-billed marsh wrens recently collected by the writer 

 at Sabine, Texas, were at first referred, with a query, to Telma- 

 todytes palustris palustris. In light of material, particularly 

 from Louisiana, which Mr. Ridgway has brought together for 

 use in connection with his work on the genus, these two speci 

 mens prove to belong to the new race which is here described. 



Telmatodytes palustris thryophilus, subsp. nov. 



Subspecific characters. Similar to Telmatodytes palustris mariana, but 

 much paler, more grayish brown above, the pileum with much less 

 black, often with almost none, the upper tail-coverts obsoletely or not at 

 all barred; chest not spotted. 



Geographical distribution. Coast region of Louisiana and eastern 

 Texas. 



Description. Type, male adult, No. 184,769, United States National 

 Museum, Biological Survey Collection; Sabine, Texas, September 3, 

 1902; H. C. Oberholser. 



Pileum sepia brown, laterally and posteriorly with a slight admixture of 

 blackish; remainder of upper surface mummy brown, the back with an 

 irregularly triangular area of black streaked with white; tail brown, with 

 black bars that on many of the feathers are confluent; wings fuscous, 

 barred with black, brown, and buff; a white superciliary stripe that is 

 extended posteriorly in a chain of white streaks encircling the hind
