246 Mr. D. A. Banuerrnan on an Ornithological 



Panis cseruleus degener. Pale Blue Titmouse. 



Parus caruleus degener Hart. ; Baunerman, Part I. pp. 47, 

 60. 



The young in first plumage have the back greyish green, 

 the underparts are paler throughout than in the adult and 

 they lack any whits on the head. The parts which in the 

 adult are white, in the young bird are dull yellow. The 

 black throat is also wanting in juvenile specimens. 



The Pale Titmouse is confined to the islands of 

 Euerteventura and Lanzarote, in both of which it is very 

 locally distributed. In Euerteventura we met with it for 

 the first time in the Tamarisk valley of La Peha, where 

 both adult and immature birds were common. This was 

 the only occasion upon which we met with Parus c. degener 

 in this island. It occurs^ however, in several districts, 

 particularly where cactus abounds, and it is also very partial 

 to fig plantations. 



In Lauzarote the range of this species is equally narrow, 

 being restricted to .the valley of Haria and immediate 

 neighbourhood, where it is very plentiful. Mr. Meade- 

 Waldo found a nest containing young on El Risco on the 

 8th of April. We were apparently too late in the year to 

 find the eggs ourselves. 



A series was obtained from Euerteventura and Lanzarote. 



Bill dark horn ; iris dark hazel ; feet slate-colour. 



Lanius excuLitor koenigi. Koenig's Grey Shrike. 



Lanius excubitor koenigi Hart. ; Bannerman, Part I. pp. 43, 

 44, 46, 48, 49, 50, 53, 54, 57, 60, 65, 89. 



The series of this Shrike which I obtained shows the 

 bird in different stages of moult ; many of the birds are in 

 very worn plumage, the primaries being quite brown. 

 Several examples have a very sandy appearance, caused in 

 most cases by the bird moulting out of the immature 

 plumage into the grey of the adult. I did not notice any 

 birds in the complete sand-coloured plumage in which 

 Mr. Meade-Waldo found one or two. 



Examples of Kcenig's Grey Shrike were found in
