Herba (Persica) robusta, facie fere Opopanacis. Folia ampla, 

 subbipinnata. Umbella prolifera, subracemosa. Umbellulse globosae, 

 breviter pedunculatse. 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 a new 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. American Marine Conchology : or Descriptions and Colored 

 Figures of the Shells of the Atlantic Coast of JSforth America. By 

 T. A. Conrad. Philadelphia : printed for the Author. — The first 

 number of a work by the above title has 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 in a 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 vnll be sufficient to contain the whole of our marine shells. 



In the present number the author has been eminently successful — 

 his descriptions are clear and his observ^ations 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 figures are 

 elegantly executed, and colored with care and accuracy. 



•Works of this kind in all the branches of the natural 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 success. 



The genus pecten is given in the present number, which contains 

 the following species :
