I have examined 7 males and 8 females of F. s. erlangeri 

 in our own collection and a further pair in the British 

 Museum, and find that the Arabian birds differ considerably 

 from Indian specimens, a large series of which has been 

 examined. 



, In the latter the upper parts are more ochraceous yellow, 

 the yellow of the chin and throat being darker. The under- 

 parts are generally darker, the breast being yellower and not 

 so pink as in P. s. erlangeri. 



As already pointed out by Hartert, the name orientalis is 

 preoccupied by Tetrao orientalis, L. I therefore propose the 

 above name. 



Type. In the British Museum. Adult male, Sambhar, 

 Rajputana, India, 25. xii. 1869. Reg. no. 89. 5. 10. 130. 



Col. Meineetzhagen also read the following description 

 of a Chat, which he was unable to identify : — 



I hesitate to give a name to a bird which may be an 

 aberration, though it is difficult to say from which species of 

 CEnanthe the present specimen varies. The specimen is a 

 female and was obtained on 7. iv. 1923 in the Wadi Diola, 

 near Helouan in Egypt. The wadi is a desolate spot, 

 frequented by CEnanthe lugens, leucopyga, and monaclia — in 

 fact, the bird was shot within a few feet of a male (Enantlie 

 monaclia. It is certainly no variety of either of the above 

 three Chats, and seems to more nearly approach (Enantlie 

 pleschanka or liispanica. But CEnanthe pie schanha is almost 

 unknown in Egypt and CEnanthe hispanica would never 

 frequent such a desolate spot. It is possibly a hybrid, but 

 even so it would be difficult to even guess at the parents. 



Description. Upper parts sandy-yellow, much the same as 

 in CEnanthe deserti homochroa, but not so pink. Ear-coverts 

 darker, lores dark brown. Upper tail-coverts white. Wings 

 dark brown. Axillaries black. Under part of edge of wiug 

 black with broad white fringes to the feathers. Uuderparts 

 pale yellowish white with a darker sandy breast-band 

 Central pair of rectrices dark brown with white bases 10 mm, 

 long. Outer pair white with black terminal mark about
