292 Mr. D. A. Bannerman an the [Ibis, 



past records of " Turdus musicus " must refer to the con- 

 tinental form, wiiicli miist now be known as Turdus 

 philomelus pkilomelus. 



The exact time when the Song-Thrushes arrive in the 

 isLands is uncertain. I doubt whether they arrive very 

 much before November (Meade-Waldo's earliest records 

 are 10 and 16 November : 12 and 19 December, Tenerife). 

 I have fouiul them very plentiful in January in tlie high 

 forests. They stay in the Archipelago until March, a few 

 remaining until April, but never nesting. 



The Song-Thrush {''Tardus musicus" of all early writers) 

 was mentioned by Ledru in 1810 from Tenerife, and since 

 that date has been recorded by every observer who has 

 written on the ornis of the group. 



It is mentioned l)y Webb and Berthelot (Orn. Canarienne, 

 p. 11) as a bird "de passage/^ and after careful investigation 

 I have come to the conclusion with Lord Rothschild that 

 the account given by Webb and Bei tlielot under the beading 

 of T. iliacus (Orn. Canarienne, p. 12) realiy belongs to the 

 Song-Tlirush (7\ p. philo77ielus, which these authors call 

 " Turdus musicus''), and should have appeared under that 

 species. My reasons together with the original quotation 

 of this paragraph are given in this paper under the next 

 species dealt with. The following is a translation of tlie 

 most interesting part of this paragraph under dispute : — 



"Jt is certain that Thrushes [les grives] arrive in the 

 winter and remain a certain time in the woods. A great 

 migration took place in 1828, above all in the island of 

 Tenerife, where tliey were very numerous. This migratory 

 wave was repeated in 1832. Thrushes were then so 

 numerous that one killed them with sticks and stones. 

 The migration commenced in November and continued at 

 intervals during part of December. These birds arrived 

 on the east coast and flooded the gardens, the greater 

 number reached the interior of the island where they took 



refuge in the Pine region They rested there three 



months in the country and then disappeared all at once.'' 



Bolle records the arrival of the Song-Thrush, and writes :
