MAMMALIA QUADRUMAN A. 249 



cited by Tsclradi as belonging to Peru, yet he has not himself observed 

 any species there. Of the Sakis he has found there Pithecia satanas ; of the 

 Tamariiis, Midas ntjimaniis, labiatus, and chrysomelas J. E. Gray has given 

 a figure of Hapale ruficenter in the ' Zoology of the Voy. of Erebus,' N. i, 

 tab. 18. Martin St. Ange has discovered, in respect to the foetus of a 

 Mandarin, that the placenta consists of two equal-sized cakes, which lie 

 opposite to each other and are separated by a zone of the chorion 2 centi- 

 metres in breadth. (Rev. Zool. p. 73.) 



PROSIMII. Under the title of Bydragen tot de Kermis 

 van de Lemuridse or Prosimii, in the ' Tijdschrift voor 

 natuurl. geschied./ xi, p. 1, J. van der Hoeven has given us 

 a monograph of the demi-monkeys, to the parcelling out of 

 whose species, though still not reduced to a precise state, 

 he has furnished valuable contributions. He gives the 

 folloAving conspectus of the species :
