The Maidstone Iguanodon. — By a letter from Mr. Mantell, dated 

 October 4, 1834, we learn that the fine specimen containing the fossil 

 bones mentioned in his communication, p. 355 has been generously 

 presented to him, by some of his friends, who purchased it in its mu- 

 tilated state for 25£. It has been chiselled out, and the pieces 

 joined ; many new bones have been developed, and it now forms one 

 of the finest specimens in Europe. A particular report of it may 

 be expected, but in the mean time it is ascertained, that the hind feet 

 of the Iguanodon "were very large, flat, and enormously strong, as 

 might indeed, a priori, be supposed. The large metatarsal bones 

 which Cuvier says, so much resemble those of the Hippopotamus 

 belong to the hind feet only ; the metatarsal are long and slender, as 

 in the recent Iguana." Mr. Mantell has been able to replace the 

 fragments of the femur, previously broken into one hundred pieces, 

 and to repair and make it quite perfect : this femur is three feet, 

 eight inches long, although shortened somewhat by compression. 



A model has been made of the lower extremity of the femur of 

 this Colossus of the reptile world. 



07i the Chrysomela vitivora. 



Prof. Silliman. — Dear Sir — By a letter from Dr. T. W. Harris, of Cambridge, 

 Mass., I learn that the insect which Mr. David Thomas described and figured as 

 new in the 26th vol. of your Amer. Journal of Science, and to which he gave the 

 name of Chrysomela vitivora, is identical with the Haltica chaLybea of Illiger. 

 Under this latter name it stands in Dr. H.'s Catalogue of the Insects of Massachu- 

 setts, appended to Prof. Hitchcock's recent report. 



PLespectfully yours, E. C. Herrick. 



New Haven, Dec. 23, 1834. 



P. S. Since the notice on page 384 was printed, we have received the Village 

 Herald from Prince Anne, Somerset County, Md., under date of Dec. 9th, sta- 

 ting that similar observations have been made there by R. H. Winder, on a plant 

 supposed to be that named by Mrs. Gerrish. We have no room to give an abstract 

 of the article.
