Parus ciNCTUS, Bodd. — In accrediting this species to the North Amer- 

 ican fauna, on the strength of specimens collected in Alaska by Mr. Lu- 

 cien M. Turner*, I inadvertantly called it "P. sibiricm, Gmel.," at the 

 time overlooking the priority of the name cinctus.

Myiarchus mexicanus, Lawr., Ann. Lye. N. Y., IX., 1869, 202 (nee Baird, B. N. Am.,

Disclaiming any desire to prolong the discussion inaugurated by me 

 in Vol. I of these Proceedings (p. 139), I however feel called upon, by 

 Mr. Sennett's comments in his " Further i^otes on the Ornithology of 

 the Rio Grande" (Bull. U. S. Geol. & Geog. Survey, Vol. V, No. 3, pp. 

 402-404), to offer a few" additional remarks on the subject. 



The synonymy of Myiarchus mexicanus (Kaup) Lawr., as given above, 

 includes all the binomial synonyms of the species in question, so far as I 

 am aware ; and in view of Mr. Sclater's positive declaration (P. Z. S. 

 1871, p. 84) that " Tyrannula mexieana of Kaup is identical with Myiar- 

 chus cooperi of Baird," I do not see how we can avoid using Kaup's 

 name for the species. Mr. Sclater's opinion certainly cannot be set 

 aside, for he made actual comparison of Kaup's type specimen wdth the 

 very examples which Professor Baird called M. cooperi, and found them 

 " identical." 



The name erythrocercus, Scl., was proposed three years before Mr. 

 Sclater made this discovery, and was, moreover, based on examples 

 from Tobago, Venezuela, and Bahia, and was described as " similar to 

 M. cooperi \i. e., mexicanus, Kaup], but much smaller," etc. 



In 1871, Mr. Lawrence, being apparently unaware of Dr. Sclater's 

 identification of T. mexicanus, Kaup, with Professor Baird's M. cooperi^ 

 and accepting the hitter's identification of mexicanus with his (L.'s) cin- 

 erascens of later date, redescribed the Mexican bird as M. yucatanensis ; 

 and in 1877, on the ground of certain differences of plumage and size, 

 separated (from M. ^'■erythrocercus") the specimens from the Lesser An- 

 tilles (Dominica) by naming them M. oheri.

t "I do not . . . hesitate to decide tliat Tf/cawnttZa mextcawa of Kaup is identical 

 with Myiarchus coopieri of Baird."— Scl., P. Z. S. 1871, p. 84." 



t "What Tyrannula cooperi, Kaup, is . . . does not now much signify. . . 

 But it is not to be supposed that Professor Kaup would make two species of the same 

 bird in the same paper. Therefore, Tyrannula cooperi of Kaup is probably not ^yiarc^us 

 cooperi of Baird." — SCL., 1. c.
