 May 25. 



Mr. Francis Harper informed the Society that althougb 

 reports had been current that the Black-crowned Night Heron 

 {Nycticorax nycticorax ncevius) colony at Roslyn, L. I., was 

 fast becoming wiped out, he had visited the place recently and 

 found it in a flourishing condition. He thought there were about 

 200 birds in the colony, a slight increase over the number in 

 1908, but fewer than in 1907, when the breeding birds were 

 estimated at from 500 to 600. 



Mr. C. G. Abbott reported seeing on Staten Island a Wood- 

 cock's {Philohela minor) nest, with four eggs, on which the bird 

 was sitting on May 13, an unusually late date. 



He also reported that five nests each of the Great Horned 

 {Bubo virginianus) and Barred Owls {Strix varia) had been dis- 

 covered this year by members of the Society within seventy-five 

 miles of New York City. 



The paper of the evening was by Mr. C. William Beebe, 

 Curator of Birds at the Bronx Zoological Park, and was entitled 

 ''Notes on a Trip to British Guiana." Mr. Beebe had but 

 recently returned from this trip, which he had made in the 

 interests of the Zoo. He displayed a series of lantern slides, 

 which included pictures of the jungles, the natives, and the 

 animal life of the country. Of especial interest were photo- 

 graphs of the Sea-cow {Trichechus manatus), a nesting Parrot, 

 and, above all, some Hoatzins (Opisthocomus) . This remark- 

 able species, in all probability, had never before been photo- 

 graphed in life. 



October 12, 1909. — The President in the chair. Thirty-one 

 members and visitors present. 



Dr. Dwight called the attention of the members to the fact 

 that the A. 0. U. convention would this year be held in New 

 York, and that the Linnsean Society would presumably be de- 

 sirous of providing luncheon to the delegates during the three 

 days of the convention, as in years past. A motion then pre- 

 vailed that the President appoint a committee of two, besides 

 himself, to attend to the matter. 



The announced program of the evening was an exhibition of
