1871.] SENATE— No. 327. 29 



(1.) Besides those fossil Mammalia mentioned in my first 

 report, I have found a large series of very well preserved spec- 

 imens of Lagomys, Cuv., Arclomys Gmel. and Arvicola, Cuv., 

 besides a lower jaw-cast of Castoroides ohiensis, Forster. I 

 found further many horns of different deer- species, and a large 

 quantity of cattle and deer- bones. Halitherium, Kaup (syn. 

 Halianassa, H. v. Meyer), is well represented by a well-preserved 

 skull, many ribs and back-bones from the miocene deposits of 

 the Basin of Mayence. Zeuglodo?i, Owen (syn. Basilosaurus, 

 Harlan), is represented by a skull, several jaw-bones and a 

 large number of teeth. The order of Cetacea is represented by 

 several bones, four ear-bones (Cetotolithes), and several teeth 

 of Delphinus. 



(2.) The collection of fossil Birds is especially rich in the 

 remains of Dinornis, Owen, for which the Museum is indebted 

 to Dr. J. Haast of Christchurch, New Zealand. Four species are 

 very well represented by these fossils, namely : Dinornis crassus, 

 D. casuarinus, D. elephantopus and D. didiformis. 



Two well-preserved skulls, one of D. casuarinus, the other of 

 D. didiformis, several rings of the larynx (Cartilago cricoidea), 

 and a piece of an egg, are among these fossils. Besides, we 

 have two good casts of the egg of Epyornis, Geoff. St. H., 

 from Madagascar, and some bone-casts of this bird. 



(3.) The collection of fossil Reptiles is represented by sev- 

 eral turtle species. We find here some typical specimens of 

 Testudo antiqua, Bronn, from the miocene formation of Hohen- 

 hoven, Swabia ; a very good cast of Palccochelys novemcosta- 

 tus Val., from the Gault of the Cap la Hove, near Havre 

 (France) ; further, Chelydra Murchisonii, Bell, from the mio- 

 cene of Oeningen, Switzerland ; some typical specimens of 

 Trachyaspis Sanctcc- Cruris , Campiche and Pictet, from the 

 cretaceous formation of St. Croix, Switzerland ; few remains of 

 Apholidemys granosa, Pomel, from the eocene formation of 

 Cuisse-la-Motte (Dep. de POise), France ; some fragments of 

 Tretosternori) Owen, from the Wealden formation of Tilgate 

 Forest, Sussex, England ; some well-preserved carapaces from 

 the London clay ; and several typical specimens of Chclone 

 valanginiensis, Pictet, from the cretaceous formation (Neoco- 

 mien) of St. Croix, Switzerland. 



The Saurian order is represented by some Crocodile remains
