Herr von Thanner (Orn. Jahrb., 1913, p. 193) that 

 Thalassidroma leucorrhoa (Vieill.), the "Alma mestre/' 

 according to the fishermen (italics mine) breeds especially 

 on Montana Clara. 



Now unless Herr von Thanner has definite proof in the 

 shape of specimens or eggs, which apparently he has not, 

 that the bird in question is undoubtedly O. leucorrhoa, we 

 must not accept the statement of the fishermen. It is very 

 unlikely, although they are often excellent observers, that 

 the fishermen distinguish between such species as 0. leu- 

 corrhoa, 0. oceanicus, O. castro, etc. As a matter of fact, 

 during my stay of seven days on Montaiia Clara we did not 

 discover a single specimen of 0. leucorrhoa. One of my 

 fishermen, however, captured in a cave a small Petrel which 

 he brought to me and called the " Alma mestre" (the same 

 nickname used for O. leucorrhoa by Herr von Thanner). 

 This bird was the Common Storm Petrel (^Thalassidroma 

 pelagica Linn.), which surely proves that the statements of 

 the fisher folk must be carefully verified before being put 

 into print. 



Podiceps nigricollis nigricollis. Black-necked Grebe. 



Podiceps n. nigricollis Brehm ; Bannerman^ Part I. p. 57. 



While encamped on the shores of the Lago Januvio in 

 Lanzarote, a small flock of Black-necked Grebes visited the 

 lake. They did not remain for long, and none Avcre obtained. 

 A rare migrant to the Canary Islands, very few records of 

 this species are forthcoming. This species has a very wide 

 range extending throughout Africa, so that it is not sur- 

 prising that it should occasionally visit the Atlantic islands. 

 Records have even been made of its visiting the Azores. 



No specimens were obtained.
