appearance on March 12; within forty-eight hours from that time, under 

 the influence of a biting norther, the mercury sank to 29° and hovered 

 about that figure for several days, so that in his semi-tropical habitat 

 this little bird is sometimes called upon to endure pretty severe weather. 

 The remaining examples were taken at intervals up to March 24, after 

 which I saw none. I found them usually in cedar brakes; never more 

 than a few rods distant from them. They were sometimes very shy, at 

 other times easily approached, but almost always pursued their vari- 

 ous avocations rather silently " (Brown). Dresser mentions the capture 

 of but one specimen — taken on the Medina River. 



Mr. W. H. Werner (Bull, i^utt. Orn. Club, lY, 77) found the species 

 breeding in the mountainous districts of Comal County, adjoining Bexar 

 County on the northeast. He says: " Their habits were similar to D. 

 virens, they were very active, always on the alert for insects, examin- 

 ing almost every limb, and now and then darting after them while on 

 the wing. * * * I found them invariably in cedar timber or cedar 

 brakes as the ranchmen call them. I was not fortunate enough to find 

 a nest until the 13th of May." 



241. Dendroica virens (Gmel. ). Black-throated Green Warbler. 



Two of these Warblers, the only ones seen, were taken at San Anto- 

 nio, one on March 20, the other on the 25th. Both of these captures 

 were distinctly disappointing, as each time when I fired it was believed 

 that the bird aimed at was a Golden-cheeked. None were seen at any 

 of the other places visited. Dresser states that it passes San Antonio 

 in the spring and autumn, and Brown records it as uncommon at 

 Boerne, arriving there March 13, and that it is found in hard wood 

 growth and never in company with B. ehrysoparia. "Seen and ob- 

 tained at Corpus Cliristi the last of March" (Sennett). Hancock also 

 saw a pair there. 



Genus SEIURUS Swainson. 



242. Seiurus noveboracensis (Gmel.). Water Thrusb. 



" (Found all the summer on the banks of the Medina. — A. L. H.). I 

 shot one in December, but did not see any more until the 24th April, 

 after which I noticed them daily" (Dresser). The statement that the 

 bird is found here in summer is manifestly incorrect. Dr. Heermann 

 probably had reference to the next species. 



243. Seiurus motacilla (Vieill.). Louisiana Water Tlirn.sb. 



Brown took a male of this species at Boerne on March 25. Not in 

 Dresser's or Hancock's lists. 



Genus GEOTHLYPIS Cabaxis. 



244. Geothlypis formosa (WiLS.). Kentucky Warbler. 



This bird is merely transient at San Antonio, according to Dresser. 

 He saw several on the Medina in May,
