A male specimen of H. Lar, adult, examined at the museum of the 

 Zoological Society, London (January 7th, 1839), agreed with the above

 as the evidences of distinction. Now, with respect to the union of the 

 toes in question, which is asserted to be as complete and close in H. 

 variegatus as in the Siamang, it is to be observed, that, unless this
