nevertheless ol'ten difficult to deteimine what species is 

 intended. 



The third work studied is certainly the most important. 

 It appeared in the form of a paper entitled " Catalogo de 

 las Aves de Tenerife observadas por Don Vincente MoMi'o/' 

 and was {)ublished in the ' Anales de la Sociedad Espaiiola 

 de llistoria Natural/ Tom v. pp. 241-358. Madrid, 1876. 



Sixty-three species are enumerated, and under the majority 

 of the species appear notes on their nestiuj; habits. Appar- 

 ently these nesting notes do not refer to the birds in the 

 Canary Islands but to their allied forms in Spain I 



These rare books can be seen in the magnificent library 

 of the Tring Museum. I have taken pains to make full use 

 of Lord Rothschild's and Dr. Hartert's kindness in lending 

 them to me, a privilege which I deeply appreciate and here 

 acknowledge. 



Had I seen these works earlier they Avould have made 

 practically no change in the systematic List ot" Autheritic 

 Species w^hicli I have already published, the majoiity of the 

 records belonging to the following Appendix B. 



In Part I. of this paj)er, p. 90 (Jan, 1919), I included, 

 when possible, the dates when naturalists actually worked 

 in the Canaries apart from the dates of publication of their 

 various works. In this connection I omitted to note that 

 Ledru (cf. Part I. p. 86) appears to have first sighted the 

 island of Palmaon the 25th of October, 1796, and says that 

 he remained one hundred aud twenty-nine days in the group, 

 sailing for the West Indies on the loth of March, 1797. 

 Many of his observations are quoted in the following 

 pages. 



Likewise in the "List of Publications^' consulted, which 

 I published on })p. 86-89 of Part I., I omitted to mention 

 tho work of Dr. Curt Floericke, entitled " Aus der hcimat 

 des Kauarienvogels," 1905, pp. 1-107 (Vienna), As noted 

 elsewhere, this work is most unreliable, and has been 

 severely criticised by Polatzek in several of his papers. It 

 is therefore suitably united with Appendix B.
