'Numerous "Lemurs" with marked ungulate characters are being discovered in the 

 older Tertiaries of the United States and elsewhere. ... I am not aware that there is any 

 means of deciding whether a given fossil skeleton, with skull, teeth, and limbs almost 

 complete, ought to be ranged with the Lemurs, the insectivora, the carnivora, or the 

 ungulates.' 



Professor HUXLEY Proceedings of the Zoological Society, 1880, p. 65.
