I have found EQUISETUM HYEMALE at Methuen and 

 Boxford during the past season. 



While dredging for animals and plants in Wenham, 

 Pleasant and Chebacco ponds, during July and August, 

 1875, I collected among the Cryptogamous plants the 

 following : 



ISOETES ECHINOSPORA Durieu var. BRAXJNII. In shallow water at 

 Pleasant pond. (The first species of Isoetes yet reported in the 

 County; doubtless others are to be found. 



Characeae (2 gen., 6 species) (named by Mr. C. C. Frost,' of Brat- 

 tleboro, Vt.). 



CHARA CORONATA var. SCHWEINITZII. Wenham pond, abundant. 



CHARA GYMNOPUS var. ELEGANS A. Br. Pleasant pond, Wenham, 

 "new to New England." 



CHARA VULGARIS L. (C. foetida of authors). Pleasant pond, Wen- 

 ham, common. 



NITELLA GRACILIS Agh. Chebacco pond, abundant. 



NITELLA FLEXILIS Agh. Wenham pond. 



? "Unknown to me, perhaps new to this region."

Any local county lists or notes on the plants of the 

 county will be gladly received. 



Capt. SAUNDERS, of Orlando, Me., presented to the 

 Institute a vampire, several snakes, and a very curious 

 bone belonging to the dorsal tin of a fish, which were 

 remarked upon by the chairman. 



"Since the above was communicated, and just as this goes to press (May, 1876), 

 I also found these species in Beverly.
