secured over five hundred specimens, and the following year over three 

 hundred and fifty. Since that time they have averaged from ten to 

 forty during the winter season. 



I am very much indebted to those who have kindly communicated 

 their observations and should be glad to receive further records from any 

 who may have observed this species within the past few months. — Ruthven

American Hawk Owl (Surnia ulula caparoch) in Rhode Island — 



I am indebted to Messrs. Angell and Cash, taxidermists, Providence, R. I., 

 for information regarding the capture of a male Hawk Owl at West Green- 

 wich, R. I., Nov. 16, 1906. The stomach was empty. I think that this 

 may be given as the first authentic record for this species in the State. 

 The only previous citation would seem rather a doubtful record (Birds 

 of Rhode Island, Howe and Sturtevant, 1899, p. 63) as follows: "The 

 only record is of one taken by Mr. W. A. Aldrich (exact locality not 

 known)." — Ruthven Deane, Chicago, III. 



Identity of Tyrannula mexicana Kaup. — In his recent paper on the 

 genus Myiarchus (Proc. Biol. Soc. Wash., XVII, pp. 21-50, 1904), E. W. 

 Nelson expressed the belief that Kaup's name Tyrannula mexicana was 

 based upon the species usually known as Myiarchus cinerascens. No 

 changes in current usage were made by him, however, these being deferred 

 until such time as Kaup's type might be examined. While in Germany 

 a few months ago, I therefore took the opportunity to visit the Darmstadt 

 Museum (Grossherzogl. Hessisches Museum) and compare this type with 

 recently collected specimens. Dr. G. von Koch of the Darmstadt Museum 

 readily found it for me and kindly extended the courtesies of the museum, 

 for which I am very grateful. The specimen has been on exhibition and 

 its color is considerably altered. The outer tail feathers, so important 

 for comparison, are faded to such an extent that their markings cannot 

 be determined except by very careful examination. In ordinary light, 

 no markings are evident, but by transmitted light the relations of the 

 light and dark areas are reasonably plain, and it may be seen that the 

 dusky on the inner web is confined chiefly to the distal third of the feather 

 and that it broadens across the tip as is characteristic of cinerascens. The 

 outer web of the feather also shows a wedge-shaped dusky area. The 

 second and third feathers underlying the outer tail feather are scarcely 

 faded and their markings unchanged. Although not so broadly dusky 

 at the tip as in some specimens, they agree with those of 'cinerascens' 

 and differ decidedly from 'mexicanus.' Direct comparisons were made 

 with specimens from the Biological Survey collection selected for the 

 purpose by Mr. Nelson (No. 144872 from Cuernavaca, Morelos, representing 

 'cinerascens' and No. 144861 from Minatitlan, Vera Cruz, representing 

 'mexicanus'). After making these comparisons, I am convinced that 

 Kaup's type represents the species usually called cinerascens and not the
