Ad. supra olivaceo-fuscus vix rufescente lavatus : subtus albus, uropygio, supracaudalibus et cauda rufes- 

 centibus : remigibus extus rufescenti-cervino tinctis : pectore cum subcaudalibus inconspicue cervino

Adult Male (Laurel, Maryland, Oct. 20th). Crown, nape, and upper parts generally olive-brown, faintly 

 tinged with rufous; rump and upper tail-coverts rusty rufous; wings dark olive-brown, the quills 

 washed with rufous on the outer web; tail rufous brown; underparts white, washed with pale buff; 

 sides of the throat and breast marked with clearly defined subtriangular dark brown spots; flanks 

 pale olivaceous brown; under tail-coverts washed with pale huff ; a dull white ring round the eye,

 legs brown; iris hazel. Total length about 7'5 inches, culmen - 65, wing 3"8, tail 2'9, tarsus 1*15. 



Adult Female (Musquash, New Brunswick, June 4th). Resembles the male above described, but the upper 

 parts are a shade paler, and there is the merest trace of buff on the breast. 



Young. Resemble the adult, but are spotted on the upper parts with rusty yellowish. 



Obs. There is a slight difference in the coloration of spring and autumn examples of this Thrush, the 

 autumn plumage being darker and browner on the upper parts than in the spring. The variation in 

 size of specimens I have measured is as follows : — males, culmen 065 to 0*7 inch, wing 3 - 6 to 3'85, tail 

 2*85 to 2'95, tarsus 1 - 15 to 1'2; females, culmen 0"62 to 0'7 inch, wing 3'5 to 3 - 75, tail 2 P 55 to 2*7, 

 tarsus l'l to T15.

 only occurring in Europe as a rare straggler. The first record of its occurrence with us is that
