Bourcier's name above cited was based on a supposed Santa Marta speci- 

 men. Unfortunately its present whereabouts are unknown, but Gould must 

 have handled it at one time, since he says " I have not placed the Trochilus 

 Duchassaigni and Thalurania Cirlina among the synonyms of the present 

 species without due consideration and a careful comparison of the typical 

 specimens one with the other. . . . The specific name Cortina not having 

 been given till a year later than my own of ccmileogularis. it must give place 

 to that term ; besides which, the bird is not a Thalurania." 



Following Gould, the name has been considered as a synonym of L. 

 cocruleogularis by all authors up to 1909, when M. Simon (Revue Frangaise 

 d'Ornithologie, I. 1909, 66) sought to transfer it to the species described by 

 Lawrence under the name Sapphironia litniinosa (Annals Lyceum Natural 

 History Nezv York, VII, 1862, 458), intimating that the difference indicated 

 in the respective descriptions was probably due to age. Although M. Simon's 

 determination has been followed by such authorities as Mr. Ridgway, Messrs. 

 Brabourne and Chubb, and Dr. Chapman, we can in nowise indorse it. 

 With a good series of both the blue-throated and the green-throated species 

 available for study, it is inconceivable that Bourcier's description, " Gorge, 

 devant du cou, thorax d'un beau bleu brillant, verdissant sur les cotes du 

 cou. Abdomen vert bronze " could apply to anything but the former. M. 

 Simon, indeed, brings forward no new evidence in support of his position, 

 and in the absence of any valid proof to the contrary we believe that Gould's 

 statement should be accepted at its face value. The only difficulty in so 

 doing arises from the fact that Bourcier assigns the vicinity of Santa Marta 

 as the type-locality of his new species ccclina, whereas we now know that the 

 region in question is inhabited by a form in which not only the throat, but 

 also the entire under parts are glittering blue. Bourcier's description being 

 so explicit, so obviously applicable to an adult bird, and so fully confirmed 

 by Gould, we have a right to conclude that his type could not possibly have 

 come from Santa Marta as he believed. Since we know that sundry other 

 species ascribed to Santa Marta by various authors really came from Pan- 

 ama instead, this difficulty is not insuperable. 



205. Lepidopyga luminosa (Lawrence). 



Six specimens : Fundacion and Fonseca. 



In accordance with the foregoing- considerations, we are obliged 

 to restore Lawrence's name, based on a specimen from Barranquilla, 

 Colombia, to the form with wholly green under parts. For a long 

 time the species appears to have been known only from the type, and 

 even as late as 1909 only three additional specimens had come to light, 

 according to M. Simon. As a result Lawrence's name was quoted 

 doubtfully, or sometimes as a synonym. The species appears from re- 

 cent researches, however, to be a common resident in the Caribbean
