101 [Vol. xxiii. 



Messrs. M. J. Nicoll and J. L. Bonhote exhibited 

 examples of a Crested Lark and a Ilouse-Sparrow, obtained 

 by themselves in the Fayum, which they believed to represent 

 hitherto undescribed races. 



The descriptions were as follows : — 



Galerida cristata mceritica, subsp. n. 



Adult male and female. Most nearly allied to G. c. nigri- 

 cans (Brehm), but with the underparts whiter and the 

 markings on the upper breast smaller, more clearly defined, 

 and fewer in number. 



Measurements of the types : — 



cJ. Culmen 15 mm.; wing 100; tarsus 235. (The 

 average wing-measurement of 16 specimens is 102'2 mm.) 

 $ . Culmen 15 mm.; wing 94*5; tarsus 23*5. 



Hab. Southern shore of Lake Birket-el-Kerun, Fayum, 

 Egypt. 15.iii. 09. A series of twenty examples was pro- 

 cured. 



Passer domesticus niloticus, subsp. n. 



Adult male. DiflFers fromP. d. rufidorsalis, Brehm, in having 

 less red on Ihe back and the grey of the head and rump 

 lighter. 



The feathers of the mantle have the red portions much 

 paler, and conspicuous pale buff margins. The light edgings 

 to the inner secondaries are narrower and much paler. 

 The crown of the head and rump are pale slate-grey, which 

 colour is continued down the back of the neck until it joins 

 the mantle. A chestnut patch extends along either side of 

 the head from behind the eye ; these patches do not, as in 

 P. d. rufidorsalis, meet on the nape. The rest of the plumage 

 is similar to that of P. d. rufidorsalis. 



Adult female. Differs from that of P. d. rufidorsalis in 

 being paler and greyer. 



Measurements of the types : — 



^ . Culmen 12 mm.; wing 77 ; tarsus 18. 

 ? . Culmen 12 mm. ; wing 74 ; tarsus 18.
