primary in this species is very narrow, but quite discernible. These two characters and the 

 different form of the head-shield, which is broadly rounded at the upper extremity will serve to 



separate it from F. leucopyga. 



Our figure of this Coot is taken from the typical specimen of Dr. Hartlaub's FuUca stricklandi 

 which has been kindly lent to us from the treasures of the Bremen Museum for this piu-pose. 



Besides the species here figured we are acquainted with three other American Coots, making" 

 altogether seven of this genus in the New World — namely 



1. FULICA COENUTA. 



Fulica cornuta, Bp. Compt. Eend. XXXVII. p. 925, (1853) : Hartl. J. f. Om. 1853, Extra-h. p. 82 : Lycornh 

 cornuta, Bp. C. E. XLIII. p. 600 : ex Bolivia. 



2. FirtlCA GIQANTEA. 



Fulica gigantea, Eyd. et Soul. Toy. Bon. Zool. p. 102, t. 8: Tach. F. P. p. 302 : Hartl. J. f. Om. 1853, Extra-h. 

 p. 80 : Phalaria gigantea, Eeich. Nat. Syst. p. XXI. : ex Peruvia alta. 



/ 3. Fulica ameeicana. 



Fulica amerieana, Gm. Baird, Birds N. Am. p. 751 : Hartl. J. f. Orn. 1853, Extra-h. p. 87, ex America Bor. univ. 

 America Centr. et inss. Antillensibus. 



The following table, taken from our paper on the American Rallidee recently read before 

 the Zoological Society, will assist in determining the seven species. 



A. Clypeo frontali carunculato 



B. Clypeo frontali non-carunculato : 



a' crisso praecipue nigro, lateraliter albo mixto ; 

 major, fleiura alari nigra 

 minor, flexura alari alba 



b' crisso prsBcipue albo, medialiter nigro 

 a" secundariis ommino concoloribus : 

 margine alari albo 

 margine alari concolore 

 b" secundariis albo terminatis : 

 major : rostro flavo 

 minor : rostro rubro notato 



1. cornuta. 



2. gigantea. 



3. ardesiaca. 



4. armillata. 



5. leucopyga. 



6. leueoptera. 



7. amerieana.
