23. Passer timidus. 



Passer timidus, Prjevalski-, Deditius, J.f. 0. 1886, p. 529. 



Adult male. Similar to P. ammodendri, and only differing in the 

 lighter colour of the rufous parts of the crown and nape, which are 

 paler and more cinnamon. Total length 6-2 inches, culmen - 5, 

 wing 3-05, tail 2-3, tarsus 075. 



Adult female. Resembles the female of P. ammodendri. Total 

 length 6 inches, culmen 0-5, wing 3 - 05, tail 2-5, tarsus 0-7. 



Hub. Desert of Gobi. 



I have not yet seen Col. Prejvalski's original description of this 

 Sparrow, but Dr. Deditius mentions it in his translation {I. c). I 

 have examined a pair of specimens which seemed to me to be scarcely 

 separable from P. ammodendri.
