BIRDS OF THE CAMBRIDGE REGION. 283 



of the pinkish suffusion on its sides. Some time afterwards I identified and 

 recorded ' it as an example of the Oregon Junco {Junco oregonus). Since then 

 Jiinco oregomis has been subdivided into several geographical forms and the 

 names of no less than three of these have been successively used for the Water- 

 town specimen.^ When I next had occasion to mention this bird in print I called 

 it — for reasons quite conclusive at the time — Junco hyemalis simfeldti? About 

 the same time it was also referred to * under this name in the A. O. U. Check-List. 

 Two years later the A. O. U. Committee decided that/w/ic^ hyemalis connectcns 

 Coues and Jjiiuo hyemalis shufcldti Coale were one and the same bird and that 

 as the former name had priority it should replace the name shufcldti!' 



Still more recently Mr. Ridgway has cited connectcns as a synonym of 

 shufcldti,^ and under the name Junco montanus has described a bird closely 

 similar to Shufeldt's Junco, but lighter and grayer in coloring, and having a 

 somewhat more easterly breeding range." This form has been since accepted as 

 a full species by the A. O. U. Committee. To it Mr. Ridgway refers most of 

 the "supposed records from east of the Missouri River " of Juncos which have 

 been called oregonus or shufcldti. He thinks, however, that " some " and " pos- 

 sibly all " of these birds (excepting one taken at Laurel, Maryland) "maybe 

 referable to J. oreganus shufcldti." At the time of expressing this opinion Mr. 

 Ridgway had not seen my Watertown specimen ; I have recently sent it to him 

 for examination and he writes me (under date of December 10, 1905) that he 

 "would unhesitatingly label" \\. Junco montanus. While I accept this determin- 

 ation, I cannot help thinking that the matter has not as yet been fully 

 and finally settled. The Montana Junco is certainly very closely related 

 to Shufeldt's Junco, and I believe that when more specimens have been 

 examined (inontanus is represented by comparatively few at present) the two 

 forms will prove to intergrade and hence to be, at the most, but subspecifically 

 distinct. The Watertown bird is referred to in the Introduction to the present 

 Memoir under its former name, Shufeldt's Junco.
