This liinl, of wliicli a sinjflo .specimen only is .so far known, is very closely 

 reliiteil to J', ivn/ni/ns, tliouoli very easily distiiigiiislKHl from it. It is con- 

 sitleralily smtiUev than rotitmtm, the bill more slender, the ujjper parts much 

 darker, lieiiij; pliimheous, not .sandy-colored; the stripes beneath darker; the 

 bill and le.gs more du.sky. Tliest^ diiferenees n)iiy not iinlieate a distinct 

 species, l)ut as tiie .siiecimen here described differs entirely from all the speci- 

 mens of a large nnmlu'r of /'. rust vn In a, it is yet entitled to consideration tis 

 ii marked variety, — jirobidily the resident race at Cape St. Lucas, where the 

 Viir. nisfratns is merely a winter visitor. 



llAiiiTs. Tin; St. Lucas Finch is a new species, in regard to the habits 

 of which nothing whatever is as yet known. It was obtained at San Jos(5, 

 in Lower (,'aliforniii, l)y Mr. .Tohn Xantus, in Decendier, 18;")!). It was found 

 in comjiany with a ilock of I'onsn-rii/iis rn,sfr(ifiis,a,nd the presumption is that 

 its habits may resemble those of that little-known species.
