334 LASIOPYGA 



Sintia sabcea Linnaeus is a composite species, its Author, as was not 

 infrequently the case in his diagnosis, confounding two species together. 

 The Cauda cinerea removes it at once from Le Callitriche F. Cuv., with 

 its grayish green tail and yellow tip, and in the longer description, Le 

 callitriche and Le Grivct (L. griseoviridis Desm.), seem to be mixed 

 up together. Under these circumstances it does not appear to be 

 judicious to employ Linnaeus' name, for it might not only continue but 

 increase the confusion already created, and another name should be 

 substituted for it, and the one available is callitrichus 1. Geoffroy 

 (I.e.). 



This is one of the most common monkeys seen in captivity, and 

 has been introduced into one or more of the West Indian Islands, and 

 also, according to Schlegel, into St. lago of the Cape Verde Islands.
