Sitta carolinensis lagunse, new subspecies. St. Lucas 



Nuthatch. 



SuHspEC. CHAR.— Similar to S/tfci raroli'iicusis arttleata^hui with the 

 vviiiijs and tail shorter, the black on the tips of the outer tail-feathers 

 more restricted. 



Types. — Male ad. (No. 14,691, collection of William Brewster. Sierra 

 de la Laguna, Lower California, May 5, 18S7; M. Ahhott Frazar). — 

 Wing, 3.41; tail, 1.97; tarsus, .72; bill from nostril, .59 inch. 



Female ad. (No. 14,705, collection of William Brewster, Siena de la 

 Laguna, Lower California, May 7, iSS7;M. Abbott Frazar). — Wing, 3.20; 

 tail. 1.73; tarsus, .67; bill from nostril, .53 inch. 



The diirerences just mentioned, though sliglit, are rcinarkal)ly 

 constant in the large series of specimens before me. Specimens 

 of .S\ c. aciilcata from variotis localities in the Rocky Mounlniii 

 region, California, and as far south along the Sierra Madre Moun- 

 tains of Mexico as Chihuahua, present very little variation in size. 

 The Lower California liirils have the wings decidedly, the tail 

 slightly, shorter than in acitlcata but the bill is fully as long and 

 slender. The ditlerence in the tail marking is a curious one. 

 The white spots on the outer three rectrices are not more extensive 

 than in 5*. c. aciilcata btit they are nearer the tips of the feathers, 

 thus narrowing the blackish apical band to from one half to three 

 quarters the width that it is in aciilcata. The third feather has 

 at most only a trace of dusky on the tip, and in a few birds none 

 whatever. Several specimens in the Lower California series have 

 the wing-quills and all the tail-feathers, except the middle pair, 

 light reddish brown at their tips.

One of several attractive possibilities discussed by Mr. Chap- 

 man, Dr. Allen, and myself before starting on the trip described 

 elsewhere in this number of 'The Auk'* was the meeting with
