 Family CERTHIIDAE 



GEEEFERS 

 93. TICHODROMA MURARIA (Linnaeus) 



Certhia muraria Linnaeus, Sys. Nat., ed. 12, vol. 1, 1766, p. 184 (S. Europe). 



One male, Paotow, Inner Mongolia, March 22; 1 male 15 miles 

 northwest of Ninghsia (Holanshan Mountains), May 16; 1 male, 

 15 miles east-southeast of Lanchow, July 12 ; and 1 female (marked 

 male), 30 miles west of Sining, Kansu, August 17. 



"While the United States National Museum has been accumulating 

 quite a series of this species from Asia, it still lacks satisfactory 

 material from Europe. A pair of birds from Saxony are much 

 lighter and have longer bills than any I have been able to examine 

 from Asia. Four females from Kashmir are darker and have 

 shorter bills than a female from Saxony. A fair series from the 

 mountains of China show quite a little variation among themselves. 

 While they seem to average a clearer, purer gray above than Kash- 

 mir specimens, yet there are birds in the series that are identical 

 with the latter, or almost so, and in any future subdivision should 

 be kept together.
