Cynocephalus, yet there are others of fully equal importance con- 

 necting it with the Simiidce, the characters being, indeed, so equally 

 balanced that the author appears to be undecided to which family it 

 should be referred. Among the characters allying Oreopitheciis to 

 the infei-ior apes are the great length of the dental series, and the 

 elongation of the last molars — especially those of the lower jaw. 

 On the other hand, anthropoid affinities are displayed in the short- 

 ness of the face, the rounding of the chin, and the contour of the 

 molars, in which the tubercles are arranged diagonally, and do not 

 exhibit the complete cross-crests of the Simiidce. The species was 

 of somewhat larger size than a Gibbon ; and it appears highly 

 probably that the author is right in considering this interesting form 

 as one of the ancestors of the existing anthropoid Apes. 



The remainder of the paper is devoted to the consideration of 

 Semnopiiheciis monspessidanus and Macacus (Liuits) florentinus of the 

 Pliocene of the Val d'Arno. The latter was originally described by 

 Cocchi as the type of a distinct genus, under the name of Aulaxinuus ; 

 and it appears that Dr. Forsyth Major's Macacus ausonianus is merely 

 a synonym of this form. 



We are much interested to learn that this memoir is one of a series 

 intended to illustrate the whole of the Mammalian fauna of the 

 Italian Tertiaries, if the necessary funds are supplied by the Govern- 

 ment. The importance of such a series cannot be overestimated, 

 not only to the students of Italian palaeontology, but likewise to 

 those of other countries — and more especiallj'^ England. We there- 

 fore most earnestly hope that the Italian Government will be induced 

 to afford the supplies necessary to continue this most important 

 work, which we feel sure will be well carried out under the direction 

 of Professor Stoppani. E- L-

THE fourth part of the third volume of this work, relating to 

 Palasozoology, has just been issued, and extends to the end of 

 the section Aves. The index and title-page of vol. iii. are also added, 

 and there is a short list of Corrigenda, chiefly in connexion with 

 the class Pisces. The Order Crocodilia occupies the first fifty pages, 

 and is regarded as comprising the three suborders of Parasuchia, 

 Pseudosuchia, and Eusuchia ; the second being founded for the 

 reception of the remarkable Triassic genera Aetosnurvs. Typotliorax, 

 and Dyoplax, while the third includes both the Eusuchia and 

 Mesosuchia of Huxley's classification. Few of the illustrations are 

 new, but the selection of published figures is such as to render Dr. 

 von Zittel's account the most completely illustrated synopsis of the 

 order that has hitherto appeared. The number of genera with 

 appended queries shows how much scope for investigation still 

 remains for any one able to undertake an extended review of available
