covered at the sides with a soft down, through which a few bristly 

 hairs are scattered. The teeth agree in all points with the cha-^ 

 racter given them in the generic description ; of the four superior 

 incisors the two lateral ones are smaller; the inferior incisors are 

 uniform in size, and regularly disposed. The interfemoral mem- 

 brane is deeply excavated. The toes are uniform in length and 

 size, and have all the same direction : the claws are partially 

 covered by stiff projecting bristles. 



The character of the mouth and lips, as given by Dr. Von Spix 

 in his generic description, applies closely to our species : the 

 latter are surrounded with a regular series of warts, and the mouth 

 is provided internally with a narrow, fimbriated, cribriform mem- 

 brane. In many particulars the Phyllostoma Jamaicense agrees 

 with the Phyll. planirostrum of Spix, figured on the xxxvith plate 

 of the work above mentioned i but it is clearly distinguished by the 

 structure and adhesion of the inferior portion of the nasal mem- 

 brane, by the absence of warts on the sides of the nose, and by 

 other particulars. 



Our specimens have an expansion of the flying membrane, 

 amounting to one foot and three inches : and the entire length, 

 from the muzzle to the extremity of the interfemoral membrane, is 

 four inches and ten lines.

On the Grand Vasa of M. Le Vaillant. 



Were I not assured of the general accuracy of M. Le Vaillant, 

 and of his nice tact in the discrimination of species, I should feel 

 inclined to consider his grand Vasa which he has figured in the 

 81st plate of his '•' Histoire des Perroquets," and the petit Vasa 

 of which he has given a figure in the succeeding plate, as varieties 

 of the same species. The general similarity which prevails be-
