Garman.] 402 [June 21, 



A seedling grape (the Iona variety) was shown, where the 

 plant had only pistillate flowers. In all these the sexes 

 were on different plants. 



Mr. W. P. Wilson read a letter addressed to Dr. Gray, 

 from Prof. De Caisne of Paris, concerning Epigwarepens L. 

 From specimens sent him he had determined a new species 

 based on the comparatively large spreading lobes of the 

 stigma. Flowers with such a stigma are fertile, but contain 

 imperfectly formed pollen, or often none. Dr. Gray thinks 

 tfhis plant may possibly be progressing towards a dioecious 

 ■condition. 



Mr. Charles Wright spoke of the unfitness of the name of 

 Diervilla tri/ida, which almost never has a trih'd peduncle. 



June 21, 1876. 



Vice-President, Mr. S. H. Scudder, in the chair. Eleven 

 persons present. 



The following paper was read: — 



Reptiles and Batraciiians collected by Allen Lesley, 

 Esq., on the Isthmus oe Panama. By 8. W. Garman. 



The collection which serves as the basis for the following notes 

 was made at a point about midway from Aspinwall to Panama, on 

 the Chagres River. Though small it was well selected, and, what 

 was especially satisfactory, it was unusually well preserved. When- 

 ever practicable these specimens have been compared with others 

 from the north or south, with the view of determining as much as 

 possible of the extent of territory occupied by each species, and of 

 the amount of variation obtaining among its representatives in differ- 

 ent parts of the habitat. Consequently such remarks as are placed 

 under several names of the list are results of a somewhat general 

 study of the species. The material for such study, in the Mus- 

 seum of Comparative Zoology, at Cambridge, is provided by the col- 

 lections of Messrs. Agassiz, Albuquerque, Bourget, Linden, Maack,
