List of Custa-Rica Birds. 317 



valus, must surely be called R. brevicarinatus, Gould, the types 

 of which came from Panama. Gassings reasons for keeping- 

 three species are unsatisfactory, and to my mind point to a 

 conclusion opposed to that at wliich he arrives — viz. that they 

 should all be united. 



ACCIPITRES. 



Asturina nitida is A. plagiata, Schl. (see Scl. & Sal v. P. Z. S. 

 1869, p. 130). A. maynirostris is A. ruficavda, Scl. & Salv. 

 [toin. cit. p. 133, and Exot. Orn. pi. Ixxxviii.). Accipiter pi- 

 leatus is A. bicolor, Vieill. (see Scl. & Salv. Exot. Orn. pi. Ixix.). 

 Rostliramus sociabilis, though, doubtless, to be found in Costa 

 Rica, must for the present be erased from the list of its birds. 

 We have no specimen from the Gulf of Nicoya, nor can 1 find 

 any mention of the species in our manuscript lists of Arce's 

 collections. 



COLUMBID^. 



Chlorcenas subvinacea, described by Mr. Lawrence in the pre- 

 sent paper, seems to be distinct from Columba niffrirostris, Scl. 

 We have no specimen which we can refer with certainty to the 

 true C. vivacea of Temminck, whose plate is hardly satisfactory 

 enough to enable me to make a comparison. The three species, 

 if there are three, are very closely allied. Geotrygon c(Eruleiceps, 

 also described by Mr. Lawrence, is G. chiriquensis, Scl. (see Exot. 

 Orn. pl.lxii.)*. G. custaricensis, another species of this difficult 

 group, 1 do not know ; it is said to belong to the group con- 

 taining G. caniceps and G. a-istata, and, I suppose, also G. vera- 

 guensis, Lawr., from the neighbouring country of Chiriqui. 



Cracid^. 



Penelope purpurascens. Costa-Rican specimens in our collec- 

 tion agree with others from Panama, and diifer materially from 

 Guatemalan examples in having the lower part of the back and 

 belly of a deep chestnut. I am not yet satisfied as to the pro- 

 per designation of this bird, which may be P. crista ta, Linn. ; 

 but it agrees fairly with Spix's figure of his Penelope jacuaca, and 

 with the specimens in the British Museum thus named. Orta-
