1^20.] Birh of the Canary Islands. 34? 



Motacilla lugubris. Pied "Wagtail. 



Motacilla lugubris Tcmm. is tirst nieiitioned by Ledru 

 (Voyage aux lies de Teuerirte, etc., vol. i. 1810, p. 183). 



Cabrera (Cattilogo, 1893, p. 44) iueludes it on the authority 

 of Ledru (/. c.) and Busto (Topogratia medica, p. 103) as a 

 rare accidental visitor. 



I cannot find that either Ledru or Busto nieution it. 



Sitta cassia. Nuthatch. 



Bolle recorded the Nuthatch (J. £. 0. 1857, p. 320) purely 

 on native information as occurring in the Mercedes Woods 

 in Tenerifc. 



He has been quoted by (Cabrera (Catalogo, 1893, p. 39). 



Sitta europsea. European Nuthatch. 



Ledru mentions this species (Voyage aux iles de Tenerifte, 

 vol. i. 1810, p. 182). 



Cabrera includes the bird (Catalogo, 1893, p. 39) on the 

 authority of Ledru, remarking that it has probably been 

 confused with S. e. ccesia. 



Lanius excubitor elegans. Elegant Shrike. 



Cabrera includes this Shrike (Lanius hemileucurus Finsch 

 & Hartl.) on his own responsibility from Fuerteventura 

 (Catalogo, 1893, p. 47). 



This North African race has probably been confused with 

 the resident Shrike Lanius excubitor kmnigi. 



Cabrera erroneously refers to the Canary Island form 

 under the name Lanius atgeriensis, for it was then con- 

 sidered identical with this Algerian race. It has since been 

 separated, however. Cabrera evidently considered there 

 were two distinct races of the Grey Shrike in the Canaries, 

 as he also mentions L. e. elegans under the name L. hemi- 

 leucurus Finsch & Hartl. 



Lanius minor. Lesser Grey Shrike. 



According to Cabrera (Catalogo, 1893, p. 47), Serra 

 (Ornithologia Canaria, 1879-1882) is responsible for the
