'The extraordinary character is the prolonged and edentulate 

 symphysis, and the great nuniber of vascular forannina on ihe 

 anterior and external part ; of course indicative of a large, fleshy 

 under lip, and a large, prehensile tongue, both adapted for a 

 large vegetable feeder. You will remennber the extraordinary 

 form and structure of the teeth of the Iguanodon. The only 

 analogy I can find is in the symphysical portion of the jaw of the 

 Sloth, and particularly in the colossal extinct Edentata, the My- 

 lodons ; with which other osteological peculiarities of my gigantic 

 reptile correspond ; for example, the vascular dentine of the 

 teeth, and the sacrum formed of five anchylosed vertebrse." 



Dr. J. M. Warren presented to the Society a beautiful 

 stuflTed specimen of Boa ; also, an admirably mounted skin 

 of a Baboon of doubtful species. Dr. W. stated that this 

 individual had possessed immense strength, having been 

 able to lift a common man from the ground, and cast him 

 from him several feet. Dr. Warren also presented a fine 

 stuffed specimen of an adult male Chimpanzee, four years 

 of age. 



Dr. Cabot announced the donation from Russell Sturgis, 

 Esq., of seventy-two valuable East India Bird skins. The 

 thanks of the Society were voted to the donor. 



Dr. Gould announced the gift of a number of specimens 

 of Rocks from Malta, from an unknown donor ; also, a do- 

 nation of several jars containing Reptiles, Fishes, and Birds 

 from Dr. F. W. Cragin, of Surinam. The thanks of the 

 Society were voted to Dr. C. for this renewed evidence of 

 his interest in our welfare. 



A valve of Chama, weighing over two hundred pounds, 

 was presented by Mr. Benjamin Kent, of Roxbury. The 

 thanks of the Society were voted to him. 



A donation of Shells was received from J. J. Dixwell, Esq. 

 a member of the Society ; also, a present of Cocoons of an 

 unknown insect, from Mr. Batchelder, of Saco, through 

 Dr. Storer.
