The broken eggs examined were all specked and spotted with 

 either brownish black or pale rnsty brown, in marked contrast 

 to each other, the coloring matter by sets, however, largely 

 alike. 



A pair of the birds, which I shot and mounted in the winter of 

 iS86 at Santa Tomas, Guatemala, measure as follows, in

17S. Piranga ludoviciana. Louisiana Tanager. — Migrant and sum- 

 mer resident in the pine forests of the Catalina and Pinal Mountains, 

 where thev breed. They first appear in the spring about April 15, in the 

 live oak belt of the Catalinas, and remain in numbers for about two 

 weeks; they are to be seen as late as May 20. After this they are absent 

 for about four or five weeks, when thej return in much greater numbers 

 than in the spring, and remain till late in September, being most abun- 

 dant in the latter part of August and the first two weeks of September. 

 This is in the Catalinas at an altitude of about 4000 feet. 



They undoubtedly breed in the pine forests of the Catalinas, for the 

 birds observed returning in late July are first adult males in full though 

 very worn plumage, followed in a few days by the females and immature 

 plumaged birds of the year. They soon congregate in large flocks, as 

 many as fifty often being together, and at this time of year their food 

 seems to be almost exclusively wild berries and small fruits of various 

 kinds, particularly a kind of grape. They were noticed in the pine forests 

 of the Catalinas as early as April 24 (see Auk, Vol. II, No. 4, p. 354, 

 October, 1885), and my latest record of them in the cafion near my 

 house was September 29, 1884, when they were observed in small num- 

 bers, all apparently young birds of the year.
