ciations. Also the citrus orchard coincides in its own seasonal 

 temperature requirements with those of the Mnckingbird. Hence 

 we find the Mockingbird a characteristic inhabitant of the citrus 

 belt; and, as the areas devoted to citrus culture increase, the Mi- 

 mine population augments. It is estimated that Mockingbirds 

 have increased five-fold, both in numbers and localities inhabited, 

 since the settlement of the country. The Mockingbird is thus 

 one of the few species which are responding favorably to intensive 

 cultivation as the valleys of southern and central California become 

 closely settled.

This appears to be the earliest description of Procellaria glacialis Linn, extant, 

 and although the author does not name the bird, there can be but little doubt 

 as to its identity with the Fulmarus glacialis glacialis. This description also 

 agrees with that of Linnaeus in 'Fauna Suecica,' Ed. 2. Stockholm, 1761, p. 51, 

 where it is said: ungue postico absque digito. Nares constant unico cylindro. 

 .... mandibulis ex o ossiculis." (Translator.)
