PENTIIETOR LUCASI. 669 



incisors are more sliarply needle-pointed, the premolars and molars, 

 though in outline and characters otherwise very similar to those of 

 Thoopterus, lack all trace of the surface cusps so consi)icuous in 

 that genus, the tail is not reduced to a mere spicule, the insertion 

 of the memt)raiies on the hind feet is different, the digits con- 

 siderably shorter, and the tibia unusually long. 



Historii in Uteratnre.— The single species of the present genus 

 was named by Dobsou (1880) " Cynopterus (FtemcJdrm) Ineccsi " ; 

 he classed it as a Ptenoeldrtis, evidently because it, like Ptenochirus 

 :/((r/ori, has only one pair of lower incisors ; but ho probably knew 

 FLpagon only or chiefly from Peters's brief description. Matschie 

 (1899), on the other hand, knew Ft. jaqori from personal inspec- 

 tion, but had not seen hcasi ; he left the latter, therefore, where 

 It was placed by Dobson. Miller (1907) was well-acquainted with 

 lucasi, but Jagori he knew only from figures and descriptions ; 

 thus he, like his predecessors, allowed the two species to stand 

 together in Ptenochirus. The fact is, however, that, in spite of the 

 number of lower incisors being the same in jaqori and lucasi, they 

 represent widely different branches of Cynopterine bats, Ptenochirus 

 jagori being very closely allied to Cgnopterm, Fenthetor lucasi to 

 Thoopterns. Systematists desirous of reducing the large number 

 of monotypic genera within the Cynopterine section of Fruit-bats 

 might conceivably propose to consider Ptenochirus (jagori) a sub- 

 genus of Cynopterus, and Fenthetor (lucasi) a subgenus of Thoopterns ■ 

 from the point of view of a natural classification of these bats there' 

 would, in fact, be no very serious objection to such proposal ; but 

 It would be impossible to place jagori and lucasi together in one 

 genus, except on condition that all Cynopterine bats (except 

 Nyctimene), irresiiective of cranial, dental, and external differences 

 are considered congeneric. '
