ii8 Lloyd's natural history. 



Cy, Pf, Mf) agrees only with the hidrisince. But no known 

 Leinuridce. possess anterior lobes and cusps on all the pre-molars, 

 so that in this respect, as in the number of its teeth, this genus 

 resembles the higher Monkeys, the Si?niidce. and Ho7ninidce^ 

 more than any existing member of the family. ... It has 

 . . a number of resemblances to Tarsius^ which is, perhaps, 

 its nearest ally among the Lemurs, although that genus has 

 three pre-molars. . . There is no doubt but that the genus 

 Anaptomorphus is the most Simian Lemur yet discovered. . ." 

 {Cope) 



The species included in this genus are A. /emulus (Cope), 

 which did not exceed the size of a Marmoset or a Red Squirrel, 

 and had short erect incisors ; A. homunculus (Cope), a species 

 founded on a cranium without a lower jaw, with the orbits not 

 so large as in Tars ins, and the skull wide behind the eyes. 

 " The A. homunculus was nocturnal in its habits," according to 

 Professor Cope, "and its food was Hke that of the smaller 

 Lemurs of Madagascar and the Malayan islands. Its size is a 

 little less than that of the Tarsius tarsius. 



Two other insufficiently characterised genera, both con- 

 sidered to be primitive Lemuroids, are Plesiadapis^ Gervais, 

 containing the species P. remensis, P. gervaisi, P. tour- 

 NESARTi, and P. daubrei, from the Lower Eocene strata of 

 Rheims, which have five-cusped lower molars, and enlarged 

 upper and lower incisors; and Frotoadapis, Lemoine, with one 

 or two high front cusps, and a low heel to its three pre-molars ; 

 the anterior molars with two pairs of opposite cusps, the pos- 

 terior molar with a fifth cusp on the hind border. P. crassi- 

 cuspiDENS, Lemoine, and P. recticuspidens, Lemoine, are 

 its two species.
