OF CONCHOLOGY. 189 



CoREECTioN OF Date OF PuBLiCATio:^'. — TVlien tlie first 

 slieet of No. 1 of this Journal was printed, the date Feb. 

 15th was affixed to the title, but various causes delayed the 

 final publication until Feb. 25th. As exactitude in such mat- 

 ters is of the greatest importance in determining questions of 

 priority, we suggest that subscribers alter the date on the title 

 of No. 1 with ink, in order to avoid possible future trouble. 



We feel, that to those who have worked long in science or 

 literature, and who, therefore, can appreciate the difficulties 

 with authors, compositors and proof-readers surrounding the 

 the hurried preparation of a new periodical, an apology is 

 scarcely necessary for the very numerous short-comings of our 

 first number. We hope and believe that the present one at

We do not give an original portrait in this number of our 

 Journal, because the large excess of colored plates, beyond the

 kindly drawing and presenting us with the first six plates of 

 this number. 



We may as well say here, that, if properly supported by 

 our subscription list, it is our intention to illustrate every species 

 published in ilus Journal. 



Our old correspondent. Dr. G. von dem Busch, of Bremen, 

 Germany, writes to us, that he would be very glad to have 

 live specimens of American Helices, for the purpose of making 

 some investigations and comparisons of their lingual dentition, 

 and for other anatomical researches. 



Conchologists, who will take the trouble to send, packed in 

 moist moss, the species of their neighborhood, directed as 

 above, per Bremen steamer from New York, will greatly 

 oblige a gentleman, who can give them a rich exchange for 

 tlieir trouble, and at the same time will aid in the important 

 work for which these specimens are required. 



We have received a note from Isaac Lea, Esq., calling at- 

 tention to the fact, that Mr. Conrad, in his "Synopsis of 

 Eocene Mollusca," has given the wrong date of 1834 to "Lea's
