Mr. William T. Davis exhibited specimens and read the following 

 note: 



The Seventeen Year Locust on Staten Island in 1906. 



A brood of 17-year locusts, Cicada septe?idecim Linn., was expected 

 in this vicinity during" the past summer. It was not, however, to be 

 expected that they would occur on Staten Island in any considerable 

 numbers, for seventeen years ago, in 1889, only a pupa skin was found. 

 (See Proc. Nat. Set. Assn. S. I. for Feb. 10, 1894.) Slightly greater 

 evidence was collected this season. In April, Mr. Alanson Skinner 

 gave me a pupa that had been found under a stone in Clove Valley, 

 and on June loth we heard a 17-year cicada singing in a tree at Rich- 

 mond Valley. It did not continue its song^ very long, and we were un- 

 able to capture the insect. 



Elsewhere, at Eastport, Long Island, the cicadas were reported in 

 some numbers {N. Y. Times, June 5, 1906). 



specimens exhibited. 



Dr. Arthur Hollick exhibited a series of specimens illustrating the 

 results obtained by macerating- and sifting the fine lignitic debris from 

 the Kreischerville Cretaceous deposits. The specimens included amber, 

 leafy twigs, cone scales, etc., the latter often well preserved and easily 

 sectioned so that they may be examined under the microscope. Photo- 

 graphic enlargemeuts of some of these sections were shown. 



Dr. Hollick stated that these specimens represented part of those 

 prepared for the forthcoming exhibition of the New York Academy of 

 Sciences at the American Museum of Natural History, to which refer- 

 ence was previously made. 



Mr. James Chapin exhibited skins of the following- birds: 



Killdeer, Oxyechus vocifera (Linn.), shot at Oakwood, Nov. 3,1906. 



Olive-sided flycatcher. Nuttallornis borealis (Swains.), shot at 

 Woodrow, Aug:. '8, [906. 



Migrant shrike. Latiius ludovicianus migrans Palmer, shot at Prince 

 Bay, Aug. 18, 1906. 



Mr. Stafiford C. Edwards exhibited gilled and porous specimens of 

 the fungus Daedalia confragosa Pers., the object of which was to show 

 the variety of form occurring in the same species. This fungus is quite 

 common in the more or less lamellate forms, the porous forms occur-
