SCIENTIFIC INTELLIGENCE. 



Explorations. — Dr. H. Berendt, a Avelbknown collector, 

 has just departed for Honduras and Guatemala, intending to 

 explore those interesting regions, principally for terrestrial 

 and fluviatile Mollusks. The principal localities to be exam- 

 ined are : the Belize River from its mouth to its source, and 

 the plateau and lakes in the Province of Peten, Guatemala. 



The cost of the expedition is defrayed principally by a few 

 of our Conckologists. 



Our Readers will be concerned to learn that Mr. John G. 

 Anthony, attached, as Malacologist, to the Scientific Explora- 

 tion of Brazil by Prof. Agassiz, has been compelled to return 

 to Cambridge, in consequence of severe illness, which attacked 

 him shortly after the arrival of the party in Rio Janeiro. 



CONCHOLOGICAL MUSEUMS IN THE UNITED STATES. — We 

 omitted to include in our List of the principal American Col- 

 lections, published in our last Number, that of 



William A. Haines, New York; 12,000 species. 



We have also to add the splendid collection of terrestrial and 

 fluviatile Mollusca possessed by 



John IT. Thomson, New Bedford, Mass.; over 6000 species. 



Mr. Thomson informs us, that there are nearly fifty private 

 collections, numbering 1000 species and upwards each, in the 

 city of New Bedford. 



Helix sculptilis, Pease, is pre-occupied by Mr. Bland for 

 an American species.
