White Billed Jacamar. Lath. Syn. SuppI, p. 113. 



Our readers will observe that in the present instance we follow 

 the example of Dr. Latham in dividing the Galbula tribe from that 

 of Alcedo. Linnaeus, and subsequently Gmelin, had placed these 

 genera together, under the term Alcedo, while most other authors 

 have regarded them as distinct. The Galbulae are the Jamacars of 

 Buffon, and of Ray and Willughby, and also Klein, before the time 

 of that French Naturalist. Brisson gave them the name of Galbula, 

 which Latham, lUiger, and most other writers have of late adopted. 

 The Galbulse differ from the birds of the Alcedo tribe in having the 

 bill generally longer ; but the chief distinction consists in the form 

 of the bill, which in Galbula is quadrangular, while in Alcedo the 

 angles are three in number instead of four. In Alcedo the tongue is 

 very short, flat, pointed and fleshy, in Galbula short and sharp 

 pointed ; and the feet of the Gabulae are formed for climbing, having 

 two toes placed forward and two behind, while in Alcedo they are 

 gressorial, or having three toes forward and one behind.
