30 Bangs — Rare or Not Well Knoivn Costa Rlcan Birds. 



verreauxi Bonap. also was taken in large series at Bolson, the two species 

 thus occurring togetlier at this point. 



Leptotila cassini vinaceiventris (Ridg.) 



Many specimens referable to this form were secured at Tenorio, Cerro 

 Sta. Maria and La Vijagua. Leptotila cassini vinaceiventris is exactly 

 intermediate in characters as Avell as in geographic position, between L. 

 cassini cassini Lawr. of Panama and Veragna and L. cassini cerviniventris 

 (8cl. & Salv.) of Guatemala and British Honduras. 



Qeotrygon albiventer Lawr. 



Two fine adults of this rare dove, so very uncommon in otlier parts of 

 Costa Rica or in Panama, were taken on Tonorio February 10, 1908. 



Qeotrygon lawrencii Salv. 



Two specimens of Lawrence's quail dove were secured on Tonorio, thus 

 extending the range of the species to the northern boundaries of Costa 

 Rica. 



Qeotrygon chiriquensis Sel. 



The capture of a male of tliis species in Cerro Sta. jNIaria January !>, 

 15)08, extends its range somewhat to the north of previous records, well 

 toward the Nicaraguan frontier. 



Neomorphus salvini Scl. 



Salvin's ground cuckoo is so seldom taken by Ijird collectors that two 

 examples secured by Underwood,' one at La Vijagua February 14, the 

 other in the Cerro Sta. ]\Iaria January 9, 1908, are worthy of record. 



Trogon underwoodi Bangs. 



Six males and one female were taken on Tenorio and in the Cerro Sta. 

 Maria in January and February, 1908. With the exception of one male 

 which comes very close to the most deeply colored example of T. auran- 

 teiveniris from Chin'cjui, this series runs very uniform and quite like the 

 type from ]\firavalles. Tlie females of the two forms are not very different, 

 and perl)aj)S T. underwoodi, in si)ite of the peculiar distribution of these 

 trogons, had better be considered a northern subspecies of T. aurantei- 

 ventris than a distinct species. 



Trogon melanocephalus illaetabilis subsp. nov. 



Type from Bolson, Costa Rica. No. 22,781, collection of E. A. i^ (). 

 Bangs, c? adult. Collected December 25, 1907, by C. F. Underwood. 



Characters. — Similar to true 2\ melanocephalus from eastern Mexico 

 south through Yucatan, eastern Guatemala and Honduras to eastern 

 Nicaragua, except that adult male has head, tln-oat and cliest dark gray- 

 slate color to blackish slate, instead of black; the adult 9 with tliese 

 parts and the l)ack and scapulars also, much paler and grayer tlian in true 

 T. melanocephalus. Size averaging slightly larger and the bill slightly 

 heavier.
