tion the desirability of continuing the rental of a table at the Naples Zoolog- 

 ical Station for the benefit of American students of biology. 



January 28th. — Samuel N. Rhoads: »Contributions to the Zoology 

 of Tennessee, No. 3, Mammals«. — Mr. Benjamin Sharp continued his 

 communication on the ethnology of Alaska. — In continuation Mr. W. G. 

 Brinton spoke of the supposed influence of Asiatic emigration on the 

 primitive civilizations of America. — A special committee of the entomo- 

 logical section of the Academy reported a mode of exterminating the tussock 

 moth, Orgyia leucostigma with which the trees of the city streets and squares 

 are so badly infested. 



February 11th. — Prof. Edw. D. Cope exhibited and described a por- 

 tion of a cetacean cranium from the Neocence beds of the Western shore of 

 Chesapeake Bay. For a whalobone whale the frontal and parietal bones 

 are of an unusual character. The presence or absence of dentition had not 

 been determined. The specimen indicated a new genus and species for which 

 the name Metopoeetus durinasus was proposed. 



February 18th. — Mr. Thos Me e h an: Contributions to the life- 

 history of plants. No. XII. — Mr. D. S. Ho Iman exhibited a new stage 

 for the microscope devised for the purpose of studying large objects. — 

 Preparations of minerals containing diatoms in transverse section and other 

 microscopic arrangements of diatoms prepared by Mr. John A. Schulze were 

 exhibited by Mr. F. J. Keeley. — Prof. Edw. D. Co pe described specimens 

 of fossil Reptilia from the Permian and Trias. They belonged to the order 

 Cotylosauria which had been described by him in 1879 and was afterward 

 characterized by Seeley from African types. The order embraces the families 

 Elginiidae, Pariasauridae and Pariotichidae, the distribution and characters 

 of which were dwelt on. New genera of Diadectidae were described under 

 the names Bolbodon and Diatomodon, the teeth of which as well as of the 

 other genera of the family were illustrated. The Platodontia may have been 

 derived from the Diadectidae. The roof over the temporal fossa and the 

 foramen for the temporal eye were illustrated by specimens. The molar 

 teeth of a species of Empedias, the cranium of Bolbodon ienuiiecfis, and the 

 lower jaw of Diatomodon were exhibited. Another form, described under the 

 name Conodectes favosus, may belong to the Diatectidae, but its relationships 

 are at present uncertain. — Edw. J. Nolan, Recording Secretary.
