C1, P2, M3) agrees only with the Zzdvisine. But no known 
Lemuride 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 Szmzzde and Homuinide, 
more than any existing member of the family. . . . It has 
a number of resemblances to Zarszus, which is, perhaps, 
its nearest ally among the Lemurs, although that genus has 
three pre-molars. . . There isno doubt but that the genus 
Anaptomorphus is the most Simian Lemur yet discovered. a 
( Cope.) 
The species included in this genus are A. £MULUS (Cope), 
which did not exceed the size of a Marmoset ora 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 Zarsius, and the skull wide behind the eyes. 
“The A. homunculus was nocturnal in its habits,” according to 
Professor Cope, “‘and its food was like that of the smaller 
Lemurs of Madagascar and the Malayan islands. Its size isa 
little less than that of the Zursius tarstus. 
Two other insufficiently characterised genera, both con- 
sidered to be primitive Lemuroids, are P/estadapis, 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 Protoadapis, 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.
