very close resemblance to Myiozetetes, perching on the dead limbs of tall 

 trees, telegraph-wires, and all kinds of exposed positions, from which it 

 catches insects on the wing. It also feeds on fruit and berries in company 

 with Myiozetetes. 



I noted several nests about Guapiles, which were built of grass and weed- 

 stalks, and were of the elbow-shaped variety peculiar to some of the tyrant- 

 birds. They were placed in the upright crotches of tall trees, always in 

 exposed positions. I did not take any of the nests, and consequently 

 cannot give a description of the eggs. 



440. Coryphotriccus albovittatus distinctus Ridgway. 



Coryphotriccus albovittatus distinctus Ridgway, Proc. Biol. Soc. Wash., XXI, 

 1908, 191 (Rio Reventazon, near Guayabo Station, March 18, 1908; Fran- 

 cisco Basulto). 



"Similar to C. albovittatus (Lawrence), from line of Panama Railway, 

 but decidedly larger; back, etc., much grayer olive; yellow of under parts 

 paler (light canary yellow instead of lemon yellow) ; and blackish area 

 on side of head much broader. Length (skin), 155 mm.; wing, 87; tail, 

 68; exposed culmen, 15.5; tarsus, 19; middle toe, 14." 



It is certainly very curious that this bird should turn up in a region 

 which has been collected in by many persons, and that, if it is distinct 

 from the Panaman species, none have been taken elsewhere. But one 

 specimen was taken by Basulto. It only emphasizes the fact that Costa 

 Rica has one of the richest and most varied bird-faunas of any region of 

 the world, and that in spite of all the work that has been done there, there 

 still remains much to be done in small districts hitherto not visited.
