49. Redpolls in the City. — On March 3, I noticed a flock of 

 these birds (Acanthis linaria) on Wellesley Street, Toronto. Owing 

 to the unusual mildness of the winter they have not been as com- 

 mon as usual this season. — J. B. Williams.

 Robins (Aferida migratoria), Cedar birds (Ampelis cedrorum), Song 

 Sparrows (Melospiza fasciata), Chipping Sparrow (Spizella sockdis),

 R. Thurston. 



54. After the presentation of reports Mr. Williams showed a 

 picture of the Hoatzin (0 pisthocomus cristatus), an anomalous bird 

 of South Amerca. It is so peculiar in both its anatomy and habits 

 that it has been made the type and sole representative of a separate 

 group. Mr. Williams described the finger ihat is found on the wing 

 of this, and after a discussion of its probable uses, and a comparison 

 with the similar organ that is found in our Coots and 'Gallinules, the 

 meeting closed.
