 The (Je.nus HYLOClIAlUS. 



Mr. Salviu, Cut. li. XVI. p. ",'4.1, cnnnitTiitps three species: //. sappktriita, 

 cyaneo, ami lactea. Of these Inctea lunst be exchicleil, as it is an At/t/rfr/n ; but 

 " Chrijs'iroiiiii rtiJicoUis " and eliciae lunst be united with llijlochuria, as in structure 

 of the bill and shape of tail they belong here, and not to Chnjstironia, where most 

 authors have placed them on account of the brilliant colour of their tails. (< 'f. Simon, 

 ('(it. Tiocliil. pp. lo, l<i, IWIT, and about bu-tra Berlejiscli in lilt. IsOO.) 



Ibilochuris sai/pkirina is not a very variable species, but si)pcimens from 

 Guiana are of a deeper, somewhat more blnish and less golden green, and their 

 central rcctrices are generally less brilliant, though this latter character is suspicions, 

 as it is also peculiar to young birds. Boncard called this race f/niancnsis. He also 

 described us a species a //. hriizilienaig {llifmrniny BinI 111. p. T), from a skin witli 

 greenish blue breast ; but this is evidently an individual aberration. Salvin's 

 description of //. napijhirimi is not exact ; the colour of the rectrices is not " ricli 

 bronze," and they have dark edges. 



//. cyaiius (Trochilus ct/aiim Vieillot) seems to be separable in tliree sub- 

 species : — 



a. H. cijanus cyanus. Kuiup with a strong cojjpery gloss, abdomen mixed 

 with grey, under tail-coverts not pure lilue, back lighter green. Hill If! — 17 mm. 

 Ilah. Brazil. 



0. II. c>/ams rostrrUd (Boncard ex Berlepsch MS). Bill 18— ^n mm. Head 

 and throat of a somewhat lighter, less reddish blue, less coppery on back and mmj), 

 abdomen deeper green. E. Peru (Rioja) and Bolivia (Rio Beni, from where Mr. A. 

 Ma.Kwell Stuart sent us a small series). 



c. II. ci/a/iiis virii/icentn's Berlp. Differing from I/.ri/ami.^ ci/iiiuia in about tiie 

 same way as //. sappkii-ina qidanensis differs from //. .t"/////'/////'/ mt piihirinn. Hill 

 15 — -IT'O mm., back without any coppery tint. 



The Genus EULAMPIS. 



This genus contains only two species in the Cdtaloifue of Bird.'i, but C clilni-o- 

 Inemus is evidently well distingnislicd from E. holn.^erireti.'i by its darker and duller 

 green throat and larger and deeper blue ])atch on the bre.ast. It is at present only 

 known from Grenada, the original locality being erroneously given as Nevis. Tlic 

 female has a longer and slightly more curved bill, and it is Gould's longirostris. 



Both holosrriceus and chlorolnemus differ from jnyuliiri.-^ in their distinctly 

 rounded tail, with the outer rectrices shorter, and their comparatively longer bills, 

 which are about one-third of the length of the wing, while in jugitlfiris the bill is about 

 one-fourth of the length of the wing; and the wings oi' Iwlosi'n'cc/is and rldorobiciiiii.H 

 arc brownish black, as in nearly all Hiunming-Hirds, while they are bright glossy 

 metallic green \n juijulf(ris,\\\ strong contrast to the velvety bl.ick glossless back. 

 It is therefore in accordance with the usual genus-splitting among the Trochilidar 

 to separate the former two generically from Kulampis, and there is (as usual) a 

 Reickenbachian name (St'i-icotcs) available for tiiis ))urpose. 



Count 15erlepsch (M/.s, 1887, ji. 294) has sejiarated two specimens supposed to 

 be from Nevis (//(A- Wiiitely!) under the name of r.i-imiit.H. Tlieir characters are a 

 longer bill, greener crown, and shorter wing: but these characters are those of the 

 female se.x, and Berlepsch's eximiiis is therefore evidently the female oijugularis.
