 palatal length, 13.5 ; length of upper molar series, 9.7 ; length of man-

 almost think, as Herr Matschie says, that that species was an albino of 

 the present one.

*E. Geoffroy described this and other species of Callithrix in 1812. 

 Humboldt's volume which contains his "Tableau Synoptique des Singes de 

 l'Amerique" bears date of 1811, a year before Geoffroy's paper appeared. As 

 Humboldt cites Geoffroy as the Author of the Species, the date must be an 

 error, which is corrected by I. Geoffroy in his "Catalogue des Primates," 1851, 

 p. vii, in the "Liste des Ouvrages, &c," where he gives it as 1815, four years 

 after the publication of E. Geoffroy's contribution.
