Dr. Dunglison described the appearances which he had witnessed, 

 in company with Professor Silliman, after the tornado of the 31st ul- 

 timo, at New Haven. The evidences appeared to him to favor the 

 idea of a gyratory motion. The direction of the storm was from

 his opinion, of a similar movement of gyration.

 were collected from the Otter Creek, Middlebury Vt., and the species 

 is described in the appendix to Long's second expedition. The cor- 

 pulentus is closely allied to the trivolvis. The former however is 

 much less rounded on the sides of the whorls ; carinse are more prom-
