In a g}'psum quarry at Yitry-sur-Seine the writer has found, in 

 addition to the nearly complete specimen of Palceotherium described by 

 M. Paul Gervais in 1873, portions of the skeletons of Anoploihenwn 

 commune^ Falceotherium magnum, P. medium, P. crassum, and P. minus, 

 XipJtodon gracile, and Dichohune lepoi'inum. At Romainvillo and at 

 Rosny he has found several bones of Hycenodon parisiense, thus esta- 

 blishing the contested fact of that fossil's presence in the Paris gypsum- 

 deposits. Remains of crocodiles, turtles, birds, and of Xij^Jwdon, com- 

 plete the list. G. A. L.

Detailed description of a portion of an ulna of this species found in 



an ossiferous conglomerate overlying the pisolitic limestone, in some 



plastic clay works at the Moulineaux, near Meudon, where a femur 



belonging to the same species had already been found. G. A. L.

 upon the affinities and ancestry of the Sirenia. Atner. Journ, 

 ser. 3, vol. ix. pp. 105-114; plate. 



Among the conclusions are the following : — The general aspect of the 

 head and face of the manatee is ungulate rather than cetacean. To this 

 extent the embryo of a lower form resembles the adult of a higher. 

 This, while contrary to the usually accepted rule, may be really an 

 exemplification of a more comprehensive law, namely, that the young 

 of animals resemble thnr ancestors. This retrograde metamorphosis of 

 the manatee points to a like retrograde evolution of the Sirenia from 

 prior ungulate forms. This idea is confirmed by what is known of the 

 geological succession of Sirenian forms. G. A. L
