Herba (Persica) robusta, facie fere Opopanacis. Folia ampla, 
subbipinnata. Umbella prolifera, subracemosa. Umbellule globose, 
breviter pedunculatie. Flores sessiles, lanugini immersi! 
The species is Dorema Ammoniacum. 
Mr. Don concludes his paper with a few observations on the plant 
which yields the analogous gum Galbanum, which he regards as also 
constituting anew genus allied to Siler, but differing essentially in 
the absence of dorsal resiniferous canals to the fruit, and in the com- 
missure being furnished with two only. He proposed for the plant 
the name of Galbanum officinale. The Bubon Galbanum of Linn. 
possesses neither the smell nor taste of Galbanum, and is altogether 
a totally different plant—Phil. Mag. and Ann. of . Phil. Jan. 1831.

1. Dies Marine Conchology: or Descriptions and Colored 
Figures of the Shells of the Atlantic Coast of North America. By 
T. A. Conrav. Philadelphia: printed for the Author —The first 
number of a work by the above title has j just made its appearance, 
and relying solely upon its own merit, has been modestly offered to. 
the scientific world. We can truly say it deserves success. 
The plan proposed by the author is to give monographs of each 
of the genera. Such species as may be subsequently discovered, 
will be given ina supplement. The work will appear in numbers 
every two months, each number to contain two colored plates, at the 
low price of three dollars per annum. It is supposed that eighteen 
numbers will be sufficient to contain the whole of our marine shells. 
n the present number the author has been eminently successful— 
his descriptions are clear and his observations always pertinent. We 
are acquainted with the ability and industry of Mr. Conrad, and most 
heartily wish him success in the present undertaking. We shall hail 
the completion of the work as a desideratum in our Fauna, and we 
feel assured that every conchologist will be desirous of placing so 
desirable an assistant to his studies on his table. 
The work is beautifully printed on fine paper, and the fisures are 
elegantly executed, and colored with care and accurac 
Works of this kind in all the branches of the saiaeal history of 
our country would be exceedingly useful, and if as well executed, 
and at so reasonable a price as this, could not, we think, fail of suceess- 
The genus pecten is given in the present number, which contains 
the following species :
