One adult from Buliia measures: wing, 20(J ; tail, ISO. One from ('ayenue : 

 wing, 265 ; tail, 180 ; and another from British Guiana: wing, 2o9 ; tail, 185 mm. 



Tlins the Trinidad l)irds belong to the smaller .southern form. Several skins 

 from Jamaica are niueli larger : wing, 2!I0 — lilO ; tail, 210 — 225 mm., and 

 aj)iiarentlv sejiaralile as a subs|)ecies. Its proper name is S. griscus jamaiccnsis 

 (Gm.) 



It is strange that all authors nsed to call the species -A', jamaiccnxis, liut as 

 C. griseus stands first in (inielin's work, it must be adojited as the specific name.

These specimens agree in coloration with a Cayenne skin, but have rather 

 shorter tails — 77 to 84 instead of 92 mm. There is, however, no difference iu the 

 length of the wing. 



Skins from S.E. Brazil are much larger, and I'orui an easily recognisable race, 

 which has to be called L. xi'mi/orij'/afu-s iiattereri (Temm.).
