^The single specimen examined from Cayman Brae is obviously different in colora- 

 tion from the five Grand Cayman examples, being much browner (deep hair brown) 

 above, and the yellow of breast and rump inclining more to chrome; but to what 

 extent these differences are due to difference of season ( the Cayman Brae specimen 

 was collected in March, those from Grand Cayman in May and July) it is of course 

 impossible to tell without a sufficient series.
