September 18, 1844. 

 Dr. Storer, Vice President, in the Chair. 



Some conversation arose on the subject of the mounds in 

 the Magalloway River, mentioned at the last meeting, sup- 

 posed to have been built by the fishes, for the purpose of 

 depositing their eggs within the pile. 



Dr. Bigelow stated, on the authority of an experienced 

 angler, that the stones are removed by the fish, for the pur- 

 pose of depositing the spawn in the cavity thereby left in 

 the sand. 



Dr. J. B. S. Jackson exhibited a parasitic Worm, one of 

 several found in the Python Natalensis. 



Dr. J. also reported on the cranium of a Woodchuck, 

 presented at the last meeting. He supposed the elongation 

 of the incisors had arisen in consequence of an injury to 

 the jaw, by which the direction of the teeth had been 

 changed, and thus their opposition being destroyed, the 

 usual wearing away of their points had not taken place. 

 The marks of disease were perceptible on the jaw. 



Dr. Storer exhibited a figure of Scomber zonatits, Mitch- 

 ill, from Wellfleet harbor. The fish was taken in a pool 

 left in the mud by the bottom of a vessel, and was the only 

 specimen he had known to be taken in Massachusetts waters. 



Mr. Henry M. Parker was proposed for membership.
