Dr. C. T. Jackson said, that he had recently observed in 

 a pond near Plymouth, Mass. the Bream {Pomotis vulgaris) 

 guarding its eggs. The nest was formed of gravel pasted 

 together with the eggs, and over it the fish kept its watch. 

 On driving it away, it constantly returned when the alarm 

 had passed. It could be approached so as to be easily 

 thrown on shore with the hands. On breaking up the nest, 

 the fish disappeared. Similar facts had been noticed of 

 late years in the habits of many fish, but Dr. Jackson was 

 not aware that they had been noticed with regard to this 

 species. 



Dr. Gould presented, in the name of Rev. Mr. Walker, a 

 box of land shells, some of which were new to the Collec- 

 tion, and some undescribed species, from forty to fifty in 

 number, all from the Gaboon river, Africa. He also pre- 

 sented, in the name of Mr. J. G. Anthony, of Cincinnati, 

 specimens of Unio collinus and U. biangulatus, and from 

 Mr. Schaeflfer of the same city, a bottle containing Reptiles. 



A note was read from the Curator of Herpetology an- 

 nouncing the donation from Dr. C. C. Holmes, of Milton, 

 Mass. of a specimen of Rattlesnake, (Crotalus horridus,) 

 obtained in that town. The thanks of the Society were 

 voted for the donation. 



A letter was read from Mr. Isaac Lea, of Philadelphia, 

 presenting a cast of Sauropus jjrimcevns, which had been 

 laid upon the table at a previous meeting without any 

 announcement of the source from which it had come. 

 The thanks of the Society were voted for the donation.
