Dr. F. Winsor made a report on a specimen of flying squir- 

 rel {Ptero?ni/s vobicella) which had been assigned to him. 

 He gave the measurements and external appearance of the in- 

 dividual, showing among other particulars an aberration in color 

 from that usually described. He showed the range of this spe- 

 cies geographically considered, and related some facts in con- 

 nection with their natural habits and instincts, &c. &c. 



Dr. Winsor's Report being accepted and placed on file, a 

 discussion in which several participated, arose, on the prevalence 

 of this species of animal in our neighborhood, and although a 

 diversity of opinion existed, yet it was supposed that its oc- 

 currence, perhaps from its habits, may be considered rare. Its 

 facility in becoming easily acquainted with man, and its attach- 

 ment in a state of captivity to the human species, with many 

 pleasing anecdotes illustrating its habits, &c., were adduced. 



On acceptance and disposal of report on Oology, Mr. John 

 M. Ives introduced a series of remarks on the habits of some 

 of our native birds, on the markings and external appearance 

 of their eggs, and on kindred subjects, — to which, from the cir- 

 cumstance of Mr. Ives's personal knowledge of our Ornithology, 

 the attention of the Institute was directed. He was re- 

 quested to aid F. W. Putnam, in his investigations in this 

 direction, to which he gave assent. 



Several specimens lately received by donation, were assigned 

 for reports thereon.
