nigris vel cinereis ; corporis lateribus et tibiis brunneis ; subalaribus et axillaribus nigricantibus brunneo 

 laVatis, remigibus infra sordide cinereis : rostro iiigro ; pedibus rubris. Long, tota circa 9-0, al» 5-6, 

 caudoB 2-5, culm. 0'75, tarsi 1-5.5. (Desor. avis typ. ex Veragua. Mus. nostr.) 

 Juv. adultis similis, sed ubique sordidior, fronte cineracea ; corpore subtus sordide brunneo, plumis singulis 

 anguste ochraceo marginatis, 



Hal. Panama, Santa Fe2, Calobre [Arce^^), Boquete and Volcan de Chiriqui, 7000- 

 10,000 feet (^rown 4). 



This species has the quill-linings ashy, not rufous, and is also distinguished by the 

 grey chest and breast, as well as by the pure white forehead, face, and throat, with a 

 distinct moustachial line of black. 



Its habits doubtless do not differ from those of the other Ground-Pigeons of the 

 forest-regions, but nothing has been recorded on the subject.

Supra saturate purpurascenti-rufa, violaceo lavata. G. lawrencii similis, sed regione parotica postica cinereo 

 lavata, collo postico clariore viridi, et pectore Isetiore cinereo distinguenda. Long, tota circa lO'O,

 tinguenda. Long, tota circa lO'O, alse 5"6. (Descr. maris et feminse ex Cartago, Costa Kica. Mus. Brit.) 



Hab. Costa Eica i, San Jose ( Van Patten % Las Cruces de la Candelaria ^ {v. Frantzius), 

 Candelaria Mts. {Boucard^^}, Volcan de Irazu (Nutting^), Azahar de Cartago, 

 Estrella de Cartago, Turrialba, Carillo (Underwood, in litt.}, Eancho Eedondo 

 (Zeledon ^). 



The true G. lawrencii is replaced in Costa Eica by this species. We have only been 

 able to compare females of the two forms, having no fully adult male of G. lawrencii 

 before us; but there can be no doubt that the Costa Eican bird is much paler in colour 

 than its Panama representative, both as regards the grey of the chest and the green 

 of the mantle. The male has the upper surface purplish-red, and the corresponding 

 sex of G. lawrencii will doubtless be found to be similar, but probably of a deeper tint. 



M. Boucard * found G. costaricensis on the Candelaria Mountains, at a height of 

 3000 to 4000 feet; the birds were always on the ground, scratching, like chickens, in 

 search of insects and seeds. ' Mr. Nutting ^ says that they were not very common on the 

 Yolcan de Irazu, and were met with only in the densest parts of the forest.
