1878.] MR. A. BOUCARD ON BIRDS FROM COSTA RICA. 49 



called " Bobo," because it is quite tame and easy to kill. I saw 

 these birds chiefly in the coffee-plantations near the streams. It9 

 cry has rather a hollow sound, sometimes like the word "mou mot," 

 or " mot mot," from which the name of the genus is derived. 



60. Urospatha martii, Spix. 



Several specimens from San Carlos, killed in February. Always 

 seen in the forest, where they make a fearful noise calling one 

 another. Its note has some resemblance to the cry of the former 

 species, but is much stronger and more hollow. They are easily 

 killed at first, but they are wilder after a few shots. I have met 

 with them in small flocks. 



61. Prionirhynchus carinatus, Du Bus. 



One specimen, a female, collected at San Carlos, February. Rare. 

 Goes by pairs in the forest. This is the first time that this species 

 has been found so far south. 



62. EUMOMOTA SUPERCILIARIS, Sw. 



One specimen, from Barranca, near Puntarenas, May. Like Mo- 

 motus lessoni and other Momotidse, it will remain for a long time 

 perched on the same branch, and the only sign of its being alive is 

 the frequent movement of its tail. 



Ordo Pici. 

 Family Picid^e. 



63. Dyctiopicus jardinei, Malh. 



Native name " Carpintero." 



Two specimens from the Volcano of Irazu and from Navarro, Jan- 

 uary and May 1877. 



64. Centurus hoffmanni, Cab. 



Two specimens, from San Jose, January, and Cartago, April ; 

 killed in the coffee-plantations. Also one specimen from Puntarenas 

 which I cannot possibly separate from this species, although it is a 

 much smaller bird. 



65. Centurus pucherani, Malh. 



Two specimens, one from San Carlos, February, the other from 

 Naranjo, April. 



66. Melanerpes formicivorus, Sw. 



Several specimens from the Volcano of Irazu, May 1877. I have 

 seen some also at Naranjo.
