p. 102, 1893) proposed the name of Tkalurania valeticiana for specimens of Tit. 

 folumbica. from " Valencia in Columbia," in whicii " the shining emerald-green of 

 the throat covers only the throat and ujiper part of the breast, while the neck, back, 

 and rnmp are all green, without the bronz}' tinge constant in 77?. columhica." The 

 female, he says, is also different in having the flanks and abdomen green. As far 

 as I can see, the colour of the neck, back, and rnmp of the type of Boucard's 

 T. valenciana does not differ more than many Bogota skins I have seen vary from 

 others from the same locality, and the extent of the green colonr of the throat seems 

 only different because the skin is differently prepared. The supposed female I 

 consider to be an immature male, which always has the flanks and abdomen green ! 

 Th. valenciana can therefore only be regarded as a synonym of Th. columbica. 



Mr. Boncard further described (Gen. H. B. p. 107) as a new species Th. 

 boliviaua from Bolivia, but his types are Th. jelskii Tacz., a species which Boncard 

 did not know and which he placed as a synonym of T. nigrofasciata. Mr. Salvin 

 (Cat. B. XVI. p. 84) also did not know Tk. jelskii, as he expressly says ; but he 

 had before him eight skins of it from Bolivia, which he enumerated as skins of 

 Th. tschwUi, thongh (p. 83) he noticed some differences between them and his real 

 Th. tschudii from Peru. Th. jelskii is, I think, more distinct than Th. tschudii, 

 which comes somewhat close to Th. nigrofasciata. 



The three forms Th. furcata, furcatoides, and refulgens are somewhat puzzling. 

 The first two especially are very closely allied, and even Boncard, who can hardly be 

 called a " lumper," has united them. Although Th. furcatoides from Brazil is pretty 

 constant, this cannot be said of Th. furcata from Guiana and Cayenne, specimens 

 from both these countries varying greatly in measurements, and especially in those 

 of the tail, some being found that are hardly distinguishable from Tk. furcatoides. 

 Th. refulgens is generally at a glance to be distinguished from Th. furcata by its 

 much larger size, and especially the longer, broader, and more forked tail, as well 

 as by the generally pure steel-blue under tail-coverts. The size, however, is not 

 absolutely constant, an approach to large specimens of Tk. furcata being foirnd now 

 and then ; and there are also specimens with narrow white borders to some of the 

 under tail-coverts. The three forms, nevertheless, are recognisable if a series is 

 compared, and the consequence is that they must be treated as subspecies. 



As the locality of Th. refulgens the island of Trinidad alone is generally given, but 

 we really do not know where the numerous trade-skins in all our collections, which 

 are said to be from Trinidad, are shot. Even admitted that most of them really are 

 from Trinidad, it is most likely that either Th. refulgens or Tk. furcata inhabits the 

 countries between British Guiana, and almost certain that the specimens approaching 

 Tk. furcata are not from the same place as the more tyjiical Th. refulgens. Boucard 

 therefore most cautiously adds a query to the locality Trinidad. 



With regard to Th. columbica and Th. venusta, I cannot help observing that 

 Central American specimens are mostly recognisable by the rather wide extent of 

 blue on the back, and that nearly all of them have also longer beaks. There is, 

 therefore, reason enough to separate this species into two forms, Tk. cobmibica typica 

 and Th. columbica venusta. 



Mr. Eugfene Simon has described one more species of Tkalurania from Yungas 

 in Bolivia, which he named Th. balzani. Its most striking characters are the 

 pure white under tail-coverts and its rather sliort wing. The type-specimens are 

 evidently fully adult birds. They have the tliroat of a golden green. Their nearest 

 ally, however, is Th. jelskii. There is no black band between the green colonr of
