NYCTICEBUS PHILIPPINUS Cabrera. 



1908. Nycticebus philippinus Cabrera, Bol. Real. Soc. Esp. Hist. Nat., vol. 8, 

 p. 137. 



Specimen. — One, from Mindanao: Catagan (Schroder). 



The discovery of a specimen of the slow lemur in the collection 

 from Mindanao is of very great interest. The specimen is preserved 

 in alcohol and is too young to show if the characters described of the 

 type by Cabrera are constant. It seems best, however, to recognize 

 the Mindanao form, as further collecting will almost surely prove the 

 species distinct from the Tawi Tawi form, N. menagensis. Cabrera's 

 name was proposed chiefly to replace menagensis, supposed at the time 

 to be without standing in nomenclature, but now becomes available 

 for the Mindanao slow lemur.
