Wagner (Abh. Ak. Miinchen, v. p. 433, and Siiugeth. v. p. 102) 

 proposes to unite these two species, as being mere varieties. Dr. Gray, 

 on the other hand, has made three species out of them. But, even 

 if the latter view be adopted, our two specimens above mentioned 

 must be referred to the true P. satanas (Hoffm.), which is the black 

 form from Para. 



Of P. chiropotes we have within the last ten years likewise 

 acquired two living specimens. Both were purchased of Mr. E. Greey 

 (one on the 18th of November, 1865, and the other on the loth Oc- 

 tober, 1866), and were, I believe, from Guiana. The latter is noticed 

 P. Z. S. 186(5, p 418, as P. satanas, as 1 was not then convinced of 

 the specific difference of the two forms. 



The plate 78 of the ' Hist. Nat. des Mammiferes ' (Saki noir) 

 undoubtedly represents Dr. Gray's Chiripotes ater, or, as I consider 

 it, the young of P. satanas. M. F. Cuvier in his letterpress refers 

 the plate to P. satanas, but observes upon the absence of the beard 

 figured in Humboldt's plate ; but this is no doubt due to the youth 

 of the specimens. Both our living examples were quite young, as is 

 evidenced by their skulls, which are now in the British Museum. 



11. HAPALE CHRYSOLEUCOS. 



I have already shown that Mico sericeus (Gray, P. Z. S. 1868, 

 p. 256, tab. 24), founded on an animal living in our Gardens in 

 1868, is the Hapale chrysoleucos of Wagner (P. Z. S. 1868, p. 592). 

 Dr. Gray, however, has more recently made it the type of a new 

 genus, Micoella, and has arranged H. chrysoleucos in this new genus 

 as a second species (see Cat. Monkeys, p. 131). Dr. Gray gives 

 the habitat of his Micoella sericeus, as " Brazil (Natterer)," whereas 

 tlie only specimen of this species in the British Museum is that which 

 was living in our Gardens in 1868, long after Natterer's decease.
