 kindly lent to me by Mr. Lawrence. The second has a rather 

 narrower bill, and is possibly different.

38. LEPTOTRICCUS. 



Type. 

 Leptotriccus, Cab. et Hein. Mus. Hem. ii. p. 54 (1859) . . L. sylviola. 



In Leptotriccus the bill is rather longer and more compressed 

 than in Pogonotriccus, and the rictal bristles not quite so dense, but 

 the forms are closely allied. The feet are weak as in Pogonotriccus, 

 but the tarsi are rather longer. One of the two recognized species 

 of this group is from Brazil, the other from Veragua.
