1920.] Birds of the Canary Islands. 341 



Appendix B. 



List of Birds that have, been recorded from unrelialde sources, 



so that the records can he dismissed as ubsohitehj valueless. 



Many of tlie birds in tliis Appendix liave been quoted 

 by more recent writers as authentic migrants, but without 

 additional proof of their genuine occurrence in tlie Canary 

 ArchipeLngo. Most of the species here included were first 

 recorded by Ledru in 1810 and then by the Spanish writers 

 from 186G to 1882. 



Birds who>e names appeared in these old lists through 

 having obviously been wrongly identified are not included 

 here. Very few of the resident birds in the Archipelago 

 bore the names which they now possess, for they were nut 

 then recognised as distinct from the Continental forms. 



For instance, the Shrike was then known as Lanius 

 alyeriensis or Lanius meridionalis, the Titmice as Parus 

 major and Parus caruleus, etc., etc. 



None of these names are included in this list, for it is 

 quite obvious that they refer to species which we now know 

 under other names, and that the Continental species nevei 

 really occuired in the Archipelago. 



Another case in point where names might be included in 

 this Appendix Ijut are best left out altogether, is afforded 

 in Cabrera's work. This author notes in his list " Regulus 

 cristatas," by which he, of course, intends I'eyulus r. teueriffce ; 

 but he also includes, as if it referred to an entirely different 

 species, "Regulus satteles," which name is a synonym of 

 R. r. teneriffa. 



I have not in this Appendix given the original reference 

 and type locality of the species included. 



Instead I have, when possible, given a reference to 

 Cabrera's work, " Cattilogo de las Aves del Archipielago 

 Canario," 1893 (quoted as '" Catalogo, 1893"), for this 

 author quotes, amongst others, from the works of the early 

 Spanish authors — Yiera, Busto, Manrique, ]\Iomp6, ami 

 Serra — and is the first author to give a complete list of the 

 birds of the Canary Archipelago since Moquin-Tandon, Webb, 

 and Berthelot wrote their monograph in 1841.
