order, consist of the single species, Lingula pyramidata Stimp., 
which was found in great numbers at a particular locality on the . 
southern side of Bird Shoals. ie 
The list of the Mollusca seems particularly full, upwards of one — 
hundred and fifty species being enumerated, all but seven of which 
are marine. ‘The marine species were referred for determination 
to Mr. Sanderson Smith, who has added various remarks respect- A 
ing the peculiarities, etc., of the specimens examined. A 
of the species were obtained with the dredge, these being collected 
jointly by Drs. Coues and Packard and Prof. Morse, who together 
thus quite thoroughly explored every part of the harbor. Dr. fe 
Coues has added important notes respecting their several stations, 
abundance, etc., which add greatly to the value of the paper. 
While a few species obtained at this locality by Drs. Stimpson 
and Gill, in 1860, were not observed, some thirteen were added to 
Dr. Stimpson’s list. . 
The partial list of the radiates collected embraces ten species 
and the occurrence of nearly as many more, not fully identified, is 
indicated. Preceding the list of the mollusca isa quite detailed 
description of the locality explored, including 
shoals, with other interesting general remarks. 
changeableness of the locality recalls to us some i 
respecting the influence of sometimes single storms upon | the faun 
of some of our coast inlets. Some years since, a heavy westerly 
February gale depressed the water in a little bay 
Cod, to such a degree that large portions of the 
ered:at low water were laid bare, and remaine 
hours. The temperature at the time being in the 
F., a crust of ice formed over these exposed flats, 
time literally filled with living Mya arenaria, ' 
species of ‘‘ razor-fish.” A few years later, on visiti 
hardly a living specimen of either of these specie 
but just beneath the surface the dead shells occu 
abundance, standing on end in their natural positions, ent 
having been killed, undoubtedly, by the chilling conseq"

A similar destruction of molluscan life,
