 " Descriptions of New Species of Accphala and Gasteropoda from the

 on the Geology of the country about the sources of the Missouri river. 

 By F. 13. Meek and F. V. Hayden, M. D. ;" which was referred to a

Dr. Leidy announced that the skeleton of the White Bear presented 

 by Dr. E. K. Kane, had been mounted and placed in the Museum. 



Dr. Leidy observed that A. Vogt, a frog and leech catcher, who fre- 

 quently accompanied Dr. Hallowell and himself when in pursuit of ob- 

 jects of Natural History, informed them that the severe cold of the 

 previous winter had destroyed great numbers of frogs and turtles. Dr. 

 L. also expressed the opinion that the house-flies were much less nume- 

 rous this season than last ; a fact which he was inclined to attribute to 

 the destruction of their larvse by the severe and protracted cold of the 

 preceding winter months. 



Dr. Bridges thought that the shade trees of our city suffered less than 

 usual from the span-worm. 



On leave granted, Dr. Leidy offered the following, which was unani- 

 mously adopted : 



Resolved, That casts in plaster of the skulls of Bootherium cavi/rons 

 and Megalom/x Jejfersoiiu, be presented to the Boston Natural History 

 Society, the British Museum, and the Zoological Museums of the Jardin 

 des Plantes, Paris, and of Berlin, Prussia.
