and Description of Birch from the Island of Jtna. I J j 



formly of a blackish colour, without a white extremity to the 

 rectrices. See Ind. Orn. 580. 



Spec. 2. Hirundo fuciphaga. Act. Holm. 33. p. 151. 



Linchi Javanis. 



Longitudo 5 poll . 



This species differs from the former in being nearly an inch 

 shorter, and in having a white abdomen and longer wings in pro- 

 portion to its size. Its nest is constructed of mosses and lichen-, 

 connected with the same gelatinous substance which composes 

 the edible nest of the preceding species. 



Spec. 3. Hirundo Klecho mihi. 



H. viridi-nigra, remigibus caudaque obscurioribus, dorso pos- 



tice griseo : subtus cinerea. 

 Samber-galeng Javanis. 



Longitudo 8^ poll. 



In young birds the abdomen is whitish, and the wing-coverts 



are banded with white at their extremities. The feathers cover- 

 ing the back and the quill-feathers are tipped with brownish- 

 grey. 



Fam. V. Sylviadte Leach. 



Dentirostres Cuvier. 



Gen. 6. Leptopteiiyx. 

 Ocypterus* Cuvier. 



* It may be necessary to state the reason for not adopting a name of so high autho- 

 rity. A genus Ocyptera has been established in entomology by Latreille, in the edi- 

 tion of his Genera Insectorum, &c, published in 1 809. As the name employed in or- 

 nithology differs only in termination, I have taken the liberty to substitute Leptopteryx, 

 which equally applies to the character of this bird.
