BUTORIDES VIRESCENS MACULATUS (Boddaert). 



Cancroma macidata Boddaert, Tabl. Planch. Enlum., 1783, p. 54 (based on 

 "Crabier tacliet6 de la Martinique," Daubenton, Planch. Enlum. No. 

 912; "Crabier verd tachete," Buffon, Hist. Nat. des Oiseaux [ed. Deux 

 Ponts], vol. 14, p. 143; orig. ed., vol. 7, 1780, p. 405) (Martinique). 



CTiars. suhsp. — Near Butorides virescens dominicanus, but wing and 

 tail longer; and posterior lower parts darker. 



Measurements. — Probable male :* Wing, 179-181 (average, 180) 

 mm.; tail, 64.2-70 (67.1); exposed culmen, 56.5-61 (58.8); heigRt of 

 bill at base, 12.5-13 (12.8); tarsus, 49.2-52.8 (51.0); middle toe, 43.5- 

 46.8 (45.2). 



Type-locality. — Martinique Island, West Indies. 



Geographical distribution. — Island of Martinique, West Indies. 



The Martinique green heron differs from Butorides virescens cubanus 

 in much larger size (except length of bill) , and paler, more purphsh 

 neck and sides of head. It is similar to Butorides virescens christo- 

 pTiorensis, but has the wing and tail longer, bill stouter, neck much 

 more purplish (less fulvescent), and the posterior lower parts darker. 

 From Butorides virescens haliamensis it is still more different by 

 reason of its much gi-eater size (except length of culmen); actually 

 as well as relatively stouter bill; darker, more purplish, less fulvescent 

 neck and sides of head; and darker posterior lower surface. It is 

 separable from Butorides virescens hypernotius, of Panama, by its 

 longer wing and tail, much paler neck, and apparently also by some- 

 what lighter posterior lower parts. 



One nearly adult bird (No. 33710, Field Mus.) is marked "male," 

 but it evidently is incorrectly sexed or is not full grown, for it is alto- 

 gether too much smaller than the other adults at hand, which we 

 assume to be males. 



The Cancroma maculata of Boddaert ^ is the "Crabier tachete de 

 la Martinique" of Daubenton,^ and also the "Crabier verd tachete"
