adult but in the young and larval stages. An important instance 

 of variation, in view of Mr. F. Lataste's recent classification of 

 the larvae of the anourous batrachians under the head of Laevo- 

 gyrinidae and Mediogyrinidae (Actes Soc. Linn. Bord.j xxxiii, 

 p. 338, 1879) is bhown by the constant presence of one, and occa- 

 sional presence of two' spiraculums, in larvae of R. sylvatica and 

 R. halecina. We agree with Mr. Allen in the careful notes cited, 

 p. 197, that R. cantabrigensis Baird, Proc. Phil. Acad. Nat. Sci., 

 Vol. vn, p. 62, differs in nothing from frequent specimens of R. 

 sylvatica. In this connection we would also refer to the possible 

 confusion arising from lack of observation on the differences the 

 same species may present in the young and adult. We agree 

 with Mr. Allen (see paper cited p. 190) in finding no differences 

 between Hyla richardii Baird, and the green tree frog of Massa- 

 chusetts, wrongly identified, we believe, as Hyla squirella Bosc. 

 We fail to see wherein the frogs differ, in either case, from Hyla 

 versicolor in the young stage. 



General Meeting, October 18, 1882. 



The President, Mr. S. H. Scudder, in the chair. Thirty- one 

 persons present. 



The Committee appointed to arrange for a memorial to Pro- 

 fessor Rogers reported, that they had invited Major Jed. Hotch- 

 kiss of Virginia to write a memoir for the Proceedings. 



Mr. Samuel Garman spoke of the part played by " medicine " 

 among the Indians, relating some stories thereon, which he had 

 learned from a Sioux. He also showed some " antelope-medicine " 

 of the Ogalalla Indians, consisting of a faggot of small sticks each 

 bearing a small bag of tobacco, which was set up on the ground 

 by a party of huntsmen on leaving for a deer hunt, as an offering 

 to the sun and moon for good luck in finding their game.
