very bulky for so small a bird, and is so loosely and carelessly 

 put together that it would appear that little labor had been expended 

 in its building. It is composed of coarse, dried grasses through- 

 out, and there is no attempt at lining with any finer material. 

 The interior diameter is two and three-quarters inches, and the 

 interior depth one inch and a half. The walls are about one 

 inch thick, but in places the grasses are allowed to straggle about 

 in so careless a manner that the walls seem at least two inches 

 in thickness. Contained in this nest were two young just hatched 

 and one e:gg^ apparently fresh, probably infertile. This egg is 

 dead white, without any spots, and is almost as much rounded 

 at one end as at tlie other. It measures .83 X .62 inches. 



The other nest is, as I have said, almost identical in appear- 

 ance with that just described, save that it is even more bulky 

 and a trifle deeper inside, and was found about July 27, in a 

 similar locality. It contained three partly incubated eggs, which 

 are the same in coloration as the one before described, and which 

 measure respectively .80 X .58, .82 X .60, and .S6 X .61 

 inches. 



A third nest is similar, and contained the same number of eggs. 

 It was taken late in July, and the eggs were almost fresh. The 

 species raises three broods at this point, and it will be seen that 

 the breeding season extends over a period of five months. 



Lophophanes wolweberi. 



Another resident and rather common species in the cailon, of 

 which a description has been given in a former paper of this 

 series, is the Bridled Titmouse {Lophophanes wolweberi). It 

 is gregarious, except during the breeding season, going about in 

 small companies. I frequently find it, especially in the fall 

 and winter months, associated with flocks of the Plumbeous Bush- 

 tit (yPsaltriparus pliimbeus)., and a pair or more of Strickland's 

 Woodpeckers {Dryobates strlcklandi) are generally found with 

 the band. I am strongly reminded of the Black-capped Titmouse 

 { Pants atricapilhis) hy this crested cousin of his; for the 

 Bridled Titmouse is quite as unsuspicious and as fond of the 

 society of man. 



Oil the two occasions that I have discovered the species breeding 

 the nests wore located in natural cavities in the live-oaks, close
