106 INSECTIVORA. 



With regard to Van der Hoeven's' observation tliat the second upper premolar 

 and last three molars of iV. javanicus have a talon directed inwards, — in a young 

 example, the second upper premolar has such a structure well developed, but in an 

 adult it is worn away to the base ; but in both, the two first molars are quadri- 

 cuspidate, and the fourth tricuspidate, according to the normal pattern, and as it 

 occurs in N. tardigradus and JV. cinereus. 



The afidnities manifested by this genus towards certain African forms is a 

 fact full of interest, and is all the more remarkable, because in some respects it 

 approaches more closely to them than to the Asiatic Loris, L. gracilis. Huxley- 

 has pointed out that, in its dentition, it approaches Arctocebus, or rather that 

 the latter differs more from the African Perodicticus than from this genus, 

 whUe it also has a certain resemblance to the Loris. Mivart,^ too, has insisted on 

 a kindred affinity between Nycticebus and Ferodicticus much more than between it 

 and Loris.
