50 MR. A. BOUCARD ON BIRDS FROM COSTA RICA. [Jan. 15, 



Ordo Passe res. 



Subordo Oscines. 



Oscines DENTIROSTRES. 



Family Turdid^e. 



67. TURDUS GRAYI, Bp. 



Native name " Giguira." 



Several specimens from San Jose, where they are found in large quan- 

 tities during the fruit-season. They are particularly fond of a small 

 fruit called in the country "cereza." My specimens differ widely 

 from the ordinary form of T. grayi in their general coloration : 

 instead of being rufous, they are ashy grey with a rufous reflection, 

 but so different in coloration that it is impossible to mistake one for 

 the other ; the sides of the abdomen are of the same colour as the 

 underside plumage, whereas in T. grayi they are rufous, nearly red. 



I have two eggs of this bird, found in one nest built in the 

 centre of an aloe growing on the road. They are green, with rufous 

 spots. 



68. Turdus plebeius, Cab. 



One specimen, from Navarro, April. 



69. Turdus nigrescens, Cab. 



Several specimens from the Volcano of Irazu. 



I never saw this species anywhere else. They are found in small 

 flocks in the oak-tree region, at the altitude of from 6000 to 10000 

 feet. I found a nest containing two eggs. They are of a pale 

 uniform green. 



70. Turdus leucauchen. 



Only one specimen, from Orozi, May. 



71. Turdus obsoletus, Lawr. 



Only one, female specimen, from Naranjo, April. This species 

 seems to be rare. It lives in the forest. 



72. Catharvs melpomene, Cab. 



Native name " Paxaro ingles" (English bird) ; I could not learn 

 why. 



Many specimens, from San Jose and Cartago, where they are found 

 on the edges of the coffee-plantations. They are often seen on the 

 ground searching for insects. They sing beautifully. 



73. Catharus frantzii, Cab. 



Two specimens from Navarro, May. Very rare. 



74. Catharus gracilirostris, Salv. 



Two specimeus from the Volcano of Irazu, April. Very rare.
