 May, t9oo [ THE CONDOR 63 cember and January a few miles further inland, where the mercury has a way of tumbling down to 6 or x8  on any clear morning during those months. The ocean side of the county has an equable temperature also, but is wind swept and bleak, and is very similar to that portion of San Francisco county be- tween the city and the ocean shore, having large areas of sand and lupines, which are the breeding homes of Zonotrichia l. gainbell. Quite a stretch of the northern-most portion of the ocean side however, is open grass land and consists of low rolling hills, with but little timber or brush. This portion has not been closely observed to my knowledge and may contain some forms unfamiliar to me. The following list of Land Birds is made up from the obserYations of many years made by my brother and myself, with occasional aid from C. A. Allen of this place. This sketch of the county is only inte. nded to give a sort of general idea of its characteristics in relation to its avifauna, enabling one to arrive at a better understanding of the subject. ff LophorO,x calforicus.
