THE AMERICAN MUSEUM JOURNAL 



of this expedition is to secure the comparatively small amount 

 of material needed to mount the skeleton of Uintatlwriuiii. 



Bamum Brown has proceeded to southwestern Dakota to ex- 

 plore certain marine Cretaceous beds, in the hope of finding 

 additional remains of Mosasaurs, or Sea-lizards, and Plesiosaurs, 

 or long-necked marine reptiles. The Museum collection is par- 

 ticularly wanting in the Plesiosanria, although it is true that we 

 have a superb specimen of Elasnwsaiiriis, presented by Mr. Jesup 

 in the second Cope collection, also a nearly complete skeleton of 

 Cryptoclidus, presented in exchange by the British Museum of 

 Natural History, from the English Middle Jurassic. Both these 

 skeletons, however, unfortunately lack the skull, a part which 

 has very rarely been found, and this is naturally the great de- 

 sideratum, which we hope to supply, at least for Elasmosaurus . 

 The skull of the English Plesiosaur is promised us from the Brit- 

 ish Museum. 



A third party, under the direction of Peter Kaison, is con- 

 tinuing the excavation of the Reed Quarry and of the Bone 

 Cabin Quarry in Wyoming, which have been so rich in results. 



The Whitney Expedition, conducted by J. W. Gidley, is con- 

 tinuing the search for fossil horses in South Dakota. Dr. W. D. 

 ^Matthew will join this expedition for a part of the season, and 

 Dr. O. P. Hay will spend a short time with Mr. Granger's expe- 

 dition in the Bridger Basin, Wyoming. 



Among the specimens recently mounted and ]3laced on ex- 

 hibition in the Department of Vertebrate Palaeontology are the 

 skeletons of the Saber-tooth Tiger from the Cope Pampean collec- 

 tion, and of the Glyptodon from the Whitney Texas collection. 

 Two new fossil proboscidean skulls make, with the two already 

 on exhibition, a unique and impressive series illustrating four 

 stages in the evolution of the Elephants. 



Professor Albert S. Bickmore sailed for Europe on June 

 lo for the purpose of making an extended tour in connection with 

 the work of the Department of Public Instruction. He will re- 

 visit Holland, Belgium, Southern Germany, .\ustria and Hun- 

 gary, and will be followed by Messrs. Abegg and Hofcr, his
