o. Hemistephania ludoviciae rectirostris (Gould). 



Dory/era recti rost rig Gonld. Intr. Mo/t. Troc/t., p. 06 (Ecuador). Hemi- 

 stephania rectirostris, Elliot, Syn. Troch., j). 81 ; Tacz. tf- Berl. P. Z. S., 1885, 

 !>. 102 (Mapoto, Ecuador); Salvia, Cat. B , xvi., p. 39 (ls<92). 



Ten adult speoiraons from Zamora and IJio Pastassa, collected in July. They 

 were in good plumage from May to September. 



There seems, indeed, to be nothing to distinguish the Ecuadorian form from 

 the common H. ludocieiae from Colombia, except the longer bill. Were the 

 ditfercnce constantly as big as given by Jlr. Salvin (/. c.) — i.e., 0-3 in., we should 

 be ])repared to keep the two forms specifically distinct, but as the length is not 

 always quite the same, and the difference often much smaller, as the measurements 

 show, wc think these intermediate forms make it necessary to degrade the Ecuadorian 

 bird to the rank of a subsjiecics. 



The ten Ecuadorian sj)ecimens in the Baron collection have the exposed culmi'U : 

 1-4: in., 1-45, 1-5, 1-48, 1-45, 1-45, 1-45, 1-4, 1-45, 1-4. 



Nine Colombian specimens before us (Bogota collections) have the exposed 

 culmen: 1-28 in., 1-35, 1-2, 1-35, 1-25, Mil, 1-26, 1-23, 1-34. 



0. Chlorostilbon prasinus (T.rss.). 

 A small but beautiful series collected in May at Gnalaijuiza, Ecuador. 



T. Thalurania hjrpochlora Gould. 

 Uio Pescado, near Naranjal, Ecuador. 



8. Thalurania nigrofasciata (Gould). 



Zamora and Oualaipiiza, Ecuador. 



The Tring ]\Iuseum has received, in exchange, from ("ouut Bcrlejiscli a skin 

 from Santa Cruz, Bolixna, labelled as Tiudtirania jelskii Tacz. It is closely allied 

 to Th. nigrofa.fciata, but the abdomen is distinctly more violet and the green throat 

 and upper breast are slightly tinged with bluish, instead of a more golden tinge in 

 Th. niyrofatsciata. There is also, perliai)s, a small difference in size. (See Salvin, 

 Cat. B., xvi., J). 84.) 



9. Chalybura intermedia sji. nov. 



Diagn. : Chalybura supra vii-idis, gutture aureo-viridi, ahdomine caerulescente 

 vel beryllino, cauda ckalybaea, nwndilndn ad basin carncu. 



Hah. Ecuador. 



Above shining green with a metallic gloss, darker on the liead and ui)per 

 tail-coverts. Tail deep steel-liliie, without the slightest wash of bronzy green. 

 Wings purplish black, wiug-eoverts like the back. Throat and upper breast shining 

 golilen green, abdomen greenish blue, beryl-green, or a little more bluish (see 

 Uitlgw., Xomend. Col., PI. X., fig. 14). All the featliers of the uuder parts very 

 narrowly bordered with brownish grey, flanks washed with brownish grey. Under 

 tail-coverts white. Upper niaudiblo black, under nwuidilile flesh-colour for about 

 two-thirds of its length, tip blackish. 



This new species differs from Chalybura caeruleogastcr (Reich.) from Bogotil, 

 Colombia, in the colour of the abdomen (which is of a rich deep blue in Ch. 

 caeruleogastcr and in the light colour of the under mandible. Besides the white
