80 REPORT OF NATIONAL MUSEUM, 1922. 



Manhattan, Nev. Others of minor importance are recorded from 

 England, Spain, and Iceland. But one purchase is recorded — that of 

 a collection of Baltic amber inclosing fossil insects. This deserves 

 special mention on account of its exhibition value. 



During several short trips to the Miocene deposits along Chesa- 

 peake Bay, Norman H. Boss secured a number of examples of well- 

 preserved cetacean remains. A skull and partial skeleton of a 

 toothed cetacean of the squalodont group is the best-preserved speci- 

 men of its kind that has yet been discovered in North America, if not 

 in the world, and a second fine specimen is a long-nosed cetacean, a 

 river dolphin type, consisting of a nearly perfect skull and lower 

 jaws with a considerable part of the skeleton. While both of these 

 are of exhibition value, their chief importance lies in their being two 

 of the very few specimens known from these deposits having skull 

 and other skeletal parts definitely associated. Both represent new 

 forms and will become types. A second accession of similar material 

 is the collection assembled by the late William Palmer, which was 

 purchased by the Smithsonian Institution and deposited in the Mu- 

 seum. This includes five good cetacean skulls and parts of others, 

 besides many individual bones. Among the skulls are representa- 

 tives of both described and undescribed genera and species. 



Valuable reptilian material was acquired b}' way of exchanges. 

 From the Victoria Memorial Museum, Geological Survey of Can- 

 ada, was received a nearly complete hind limb and foot of a large 

 carnivorous dinosaur, Gorgosaurus; a tail club of an armored dino- 

 saur: and the fore limbs, feet, and pectoral girdle of a small tracho- 

 dont dinosaur. All three of these forms from the Belly Eiver and 

 Edmonton formations of Canada are new to the collections and are 

 suitable for exhibition. Other exchanges include cervical and dorsal 

 vertebrae of the large Permian reptile, Edaphosaurus, remains of 

 which are rare, and a nearly complete fossil turtle of the genus 

 Boremys, the former from the University of Chicago and the latter 

 from the University of Alberta, Edmonton, Alberta. 



The John A. Savage Co., Crosby, Minn., presented a collection of 

 skulls and several hundred bones of extinct buffaloes from the 

 Pleistocene of Minnesota, uncovered during mining operations. No 

 less than 14 individuals are represented, mostly pertaining to the 

 species Bison occidental is, from which it will be possible to select 

 material for a good composite mount. 



The Museum was fortunate in the acquisition of parts of the skin, 

 hair, muscular tissue, and stomach contents of the famous Bere- 

 sovka mammoth from Siberia, procured from the collector, E. W. 

 Pfizenmayer, Stuttgart, Germany. The preservation of the soft
