Reviews — Prof. Edward D. Cope — 



animals differ, more than was at first supposed, from existing 

 types. But the author is unable to separate the group from the 

 Insectivora by ordinal characters. Eleven genera are comprised 

 in this tribe, among them being Microsyops with two species ; and 



Hyopsodus vicarius. 

 a. Premaxillary and maxillary, b. Mandible. 



TomitJieriwm closely allied to Adapts of Cuvier, but having two incisor 

 teeth instead of three. TomWterium is an animal with slender limbs 

 and elongated femora, and the limbs generally have much of a quad- 

 rumanous character, and these resemblances are supported by those 

 of the lower jaw and teeth ; but in the form of the humerus there 

 is resemblance to Lemurs. The only species is T. rostratum. Pelycodus 



Anaptomorphus homunculus. Nat. size. 

 «, b. Side views. c. From above. cl. From below, 

 is distinguished from Tomitherium by having the third trochanter 

 in the middle of the shaft ; and it has two roots to the second pre- 

 molar. Other characters are shown in five species described. Sarco- 

 lemur is an allied genus, distinguished by having acute cusps on the 

 heels of the true molar teeth. Eyopsodus is known from the man- 

 dibles of five species, and is distinguished by the simple inner tubercle, 

 with cusps at the angles of the heels of the molars. 



The Prosimise are distinguished from the Mesodonta by having an 

 opposable hallux which does not exist in the genus Pelycodus. The 

 author states that CMromys represents a primary division of the
