Diagn.-Minor : nigra : dorso interdum fusco lavato : barba minus crassa. Hab. Lower Amazon, near Para (Hoffm. et Natt.) ; British Guiana (Schomb.) Wagner (Abh. Ak. Miinchen, v. p. 433, and Saugeth. 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 teu 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 1 5th October, 1866), and were, I believe, from Guiana. The latter is noticed P. Z. S. 1866, 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 Ghiripotes 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 tbe habitat of his Micoella sericeus, as " Brazil (Natterer)," whereas the only specimen of this species in the British Museum is that which was living in our Gardens in 1868, long after Natterer's decease. 12.
