ADDITIONS TO YALE COLLEGE MUSEUM. 



American naturalists are congratulating themselves upon 

 the acquisition by Professor Marsh, for the museum at Yale 

 College, of the finest specimen of pterodactyl yet discovered. 

 This was recently found in Bavaria, and was especially char- 

 acterized by exhibiting distinct indications of the membranes 

 connecting the bones of the wing, which in this respect some- 

 what resembled those of the bat. Of the numerous speci- 

 mens of this flying reptile in public and private museums, no 

 others have exhibited this character to any thing like the 

 same degree, and much emulation w^as excited in regard to 

 its acquisition. It is understood that the British Museum, the 

 Berlin Museum, the Museum of Comparative Zoology at Cam- 

 bridge, and other great establishments, were all negotiating 

 for the purchase ; but Professor Marsh was the only one who 

 gave carte blanche by telegraph to the owner, authorizing 

 him to name his price. 



Another important addition made by the Professor to the 

 inuseum of Yale is the Zeltner collection of Central Amer- 

 ican antiquities, gathered by Mr. Zeltner during a period of 

 several years' service as French consul at Panama. The col- 

 lection embraces a A^ery fine series of gold images from the 

 Chiriqui graves, as w^ell as about a hundred pieces of pot- 

 tery. They constitute the originals of the illustrations of 

 Zeltner in his work on the antiquities of Chiriqui. 



PTERODACTYL IN THE CAMBRIDGE MUSEUM. 



Among the recent additions to the Museum of Compara- 

 tive Zoology at Cambridge is a very complete specimen of 

 pterodactyl, which is believed by Professor Agassiz to be one 

 of the most perfect illustrations of the genus extant. It has 

 already furnished him the means of correcting some impor- 

 tant errors, its special value being in the fact that the two 

 sides are preserved upon corresponding slabs, such details 

 as are not appreciable in one slab being evident in the 

 other. 



The restorations by Wagler and Goldfuss are proved by 

 this specimen to be imperfect or unnatural; that of the for-
