South-American Monkeys, Bats, de. 457 
based on Sagouin, a quoted synonym of C. jacchus, also 
indicates that species as its type. 
Sagouin, Lacépéde, had as its only species Sagouin jacchus, 
the type species of Callithriz, into whose synonymy it will 
therefore fall. 
Hapale, \liger, 1811, being put as a classical renaming of 
“ Saguinus, Cuvier, Duméril, Lacépéde,” will equally have 
C. jacchus as its type. 
These conclusions may be tabulated as follows :— 
1. Titi Monkeys. 
CALLICEBUS, nom. nov. 
Callithrix, Geoff. Ann. Mus. xix. p. 112 (181%), et auctorum pluri- 
morum (nec Erxleben, 1777). 
“ Saguinus, Lac.,” Lesson, Man. Mamm. p. 56 (1827) (nec Sagouin, 
Lac. 1799, nec “ Saguinus, Lac.,” Lliger, 1811), 
Type C. personatus, Geott. 
2. True Marmosets. 
CALLITHRIX, Erxl. 
Caluithriz, Yirxl. Syst. R. A. p. 55 (1777). 
Sagoinus, Kerr, Linn. An. K. p. 80 (1792). 
Sagouin, Lacépéde, Tabl. Mamm. (1799). 
Hapale, Il. Prody. Syst., Mamm. p. 71 (1811). 
Jacchus, i. Geoff. t. c. p. 118 (1812). 
Type of all these names C. jacchus, Linn. 
3. Tamarins. 
Mipas, Geoff. 
Midas, Geoff. t. ce. p. 120 (1812). 
Type MZ. midas, Linn. 
The family name for the Marmosets will be Callitrichide. 
Anthorhina picata, sp. n. 
General characters of A. longifolium, Wagn., with which 
it shares the comparatively uncrenulated state of the edges of 
the lancet and other structural details, as described by Wagner 
and Peters. Margins of the long lancet and anterior edges of 
ears prominently bairy. Wings to the base of the metatarsus. 
Calcars shorter than in A. longifolium.
