Remarks.—T he transverse strize are usually almost obsolete on 
the upper whorls, while the longitudinal sulcations become en- 
tirely so on about the last whorl and a half. ‘The striz are con- 
tinued to the very base, which together with the columella are 
brown. The color of the last whorl and a half is generally 
yellowish, while the rest of the shell is dark brown. The lower 
whorls are frequently much more convex than the upper. The 
mouth is ‘05 of an inch in length, and :025 wide. [I at first mis- 
took this shell for a Twurritelia, from the fact of the canal not 
being added until the shell has attained its full growth. This 
species might be regarded as consisting of dwarf specimens of the 
Cerithium Sayii, Menke, but it is not more than half the size of 
that shell, its whorls are more convex, its cancellations more ob- 
solete, and the shape of the canal is totally different, being much 
longer and less oblique. It resembles it however in its mode of 
growth, the lower wnons Paine entirely different from the upper.

Art. XII.— Observations on the Storm of cori 15, eo? 
by Wituram C. Repriecp, A. 
. Read before the Aeriees Philosophical Society, 3 Jan. 15, 1841. 
‘ln the table and map which are annexed to these remarks will 
be found the observations which have been obtained of the di- 
rection of wind in this storm, in the states of Connecticut, Rhode 
Island, Massachusetts, New Jersey, and parts of the states of 
Maine, New Hampshire, Vermont, and New York. ; 
‘The arrows on the map denote, approximately, the direction of 
wind, at or near the hour of noon, at the several places of observa- 
tion. The concentric lines, adiwis at intervals of thirty miles, were 
added, not as precisely indicatiag the true course of the wind, but 
to afford better means of comparison for the several observations. 
Tt will be seen, that of forty-eight distinct sets of observations, 
which are comprised in the annexed schedule, about oy, are
