100 ORDER II. 



Mr. Martin, we believe, proposed in lieu of terms 

 rather harsh, though to a certain extent truly expla- 

 natory, to substitute names with a patronymic form 

 more readly retained ; and, therefore, gave those of 

 Simiadce to the first, and CeUdoe and Lemuridce to 

 the second and third. In a fossil state, quadru- 

 rnana nearly allied to existing species, have lately 

 been detected. 



Simiadce, or apes of the Old World. The thumb 

 antagonising with the fingers, except where rudi- 

 mental. 



Dentition incisors J can. \ \ 

 pr. mol. | | molars f f = 32. 



Nostrils divided by narrow septum opening down- 

 wards; cheek-pouches, and membranous laryngal 

 saculi, not constant characters. 



The great Indian islands seem to be the centre of 

 this form of animals, because there they are in the 

 highest condition of organization and stature, and 

 in the greatest number of species. In the hotter 

 regions of Continental Asia, and in the whole of 

 Africa, the genera are local to each ; in Madagascar 

 their presence is supplied by lemurs ; in the island 

 of Mauritius they have been imported; and per- 

 haps also, though at a remote period, to Gibraltar. 



The larger species, and some others, may congre- 

 gate only in families; but the greater number of 

 simiadce are gregarious, with more intelligence and 

 aptitude than their indocility and petulance allows 

 them fully to use* They are not so diurnal in habit, 

 but that some species will rob by night, or at least
