tions, especially OA^er the tule swamps. In May, when it was less^ abund- 

 ant, I noticed two nests in casings over doors of private dwellings. 



I have not recognized it at Murphy's or Big Trees. A large scattered 

 flock was seen at Stockton as late as December 5, 1878.

'*47. Tachycineta thalassiua, (Swains.). — Violet-green Swalloiv. 



This beautiful bird was first recognized August 7, at Dunbar's Mill, 

 where at least a hundred were in sight. Three days afterward it was 

 seen flying over the meadows at Big Trees, and thereafter nearly ev^ery 

 day until August 27, 1878. 



They chose as a resting place the top branches of a tall dead pine near 

 the hotel, out of shooting range, and often when flying were so high as 

 to be seen with difficidty ; occasionally, however, they mingled with the 

 Barn Swallows near the ground.

48. Stelgidopteryx serripennis, (And.). — Eouf/h-wiiujcd Ba)ik ISwallow. 



This bird arrived at Murphy's March 15, 1877, and remained until 

 May 3, and probably later. They constituted only a fraction of ihe 

 multitude of Swallows of the place, and were, perhaps, altogether not 

 more than two dozen in number. I have not seen it elsewhere.

This bird I have found at all places where I have collected in summer, 

 but nowhere abundant. It arrived at Murphy's April 2G, 1877, and at 

 Stockton May 1, 1878. 



It was rare at Murphy's about September 1, and was not seen at 

 Stockton on or after the 7th of that month.
