lection), and found it absolutely identical with the type of C. angusti- 

 pennis (= gibsoni). We now know, however, that C. gibsoni comes 

 from another part of Colombia, and that the only form of this group 

 occurring in the lower Magdalena Valley is C. haeberlinii. It follows 

 either that Bourcier's supposed type has been misidentified, or that 

 it did not come from Carthagena. Boucard, indeed, distinctly says that 

 the type in question is in his collection, and that it came from Santa 

 Marta ! If he is correct, then chrysogaster would become the proper 

 specific appellation for the species now known as C. haeberlinii. It 

 thus is desirable to determine which of these two specimens has the 

 better claim to be the actual type of Bourcier's description. 



Since the above was written M. Simon has gone into this case also, 

 and we venture to give a translation of his remarks : " Bourcier's de- 

 scription leaves a little doubt because of his statement ' bill of a brown- 

 ish-black,' but the rest corresponds to the bird most often designated 

 under the name C. hacbcrlini Reichenbach; the indication of Cartha- 

 gena conforms to the habitat of this species to the exclusion of any 

 other. The bird in the Boucard collection, labeled ' C. chrysogaster 

 de Sta Martha, Nouvelle Grenade, 1853, type de Bourcier,' is certainly 

 not the type of Bourcier described in 1843, but it has perhaps been 

 determined by him in the old collection of Riocourt. In the British 

 Museum another supposed type of T. chrysogaster Bourc. is, accord- 

 ing to Salvin, C. gibsoni." 



The several individuals of this species above recorded were shot in 

 scrubby woodlands at Mamatoco and Fonseca. It was common also 

 at Valencia, in open spots in the forest. A female taken at this latter 

 locality by Simons has been referred to C. " atala " ( = caribccus) b> 

 Salvin, but inasmuch as it is C. haeberlinii which occurs at Fonseca, 

 farther northeast, we feel safe in referring this record to the present 

 species.

Three specimens : Rio Hacha. 



This is one of the species of the arid coast district of northern Ven- 

 ezuela, reaching the Santa Marta region in the extreme northeastern 

 part, at Rio Hacha, where the same conditions obtain. The three 

 specimens (all males) agree with a series from Curaqao in small size 

 and shape of the tail, but the bill (in the skin) is pale underneath, al- 

 most as. in C. haeberlinii. '
