specimens received from Mr. H. H. Keays^ by wtom it was 
made at Inca Mine, in S.E. Peru (lat. 13° 31' S., long. 
70° W., alt. 6000 feet) : Chlorochrysa fulgentissima, Malaco- 
thraupis castaneiceps, Euphonia xanthogastra hrunneifrons, 
Chlorospingus flavigularis parvirostris, Ochthceca keaysi, and 
Terenura ooanthonota. The Chlorochrysa is apparently the 
same as that described and figured in this Journal (Ibis, 
1901, p. 716, pi. XV.) by Graf. v. Berlepsch and M. Stolzmann 
as C. hedwig(je ; and if so, Mr. Chapman's name (August 1901) 
will have priority. 
46. Clark on the Affinities of the Humming -birds, 
[Are Humming-birds Cypseloid or Caprimulgoid ? By Hubert Lyman 
Clark. Science, New Ser. xv. p. 108 (1902).] 
After quoting Prof. D'Arcy Thompson's concluding 
paragraph in his paper on the pterylosis of Patagona gigas 
(P. Z. S. 1901, p. 311) and Dr. Shufeldt's ' Studies of the 
Macrochires ' (which take exactly opposite views as to the 
relationship of the Trochilidse), Mr. Clark, who has just 
completed a careful examination of certain members of this 
family and of the Cypselidse and Caprimulgidse, pronounces 
as follows : — 
'* I am led to disagree with Professor Thompson that the 
Humming-birds are nearer to the Goatsuckers than to the 
Swifts, and I must dissent quite as strongly from Dr. Shu- 
feldt's opinion that the pteryloses of Swifts and Humming- 
birds are ' essentially different.' To my mind the Swifts 
and Humming-birds are pterylographically nearer each other 
than are Grouse and Guans, and almost as nearly allied as 
Grouse and Quail. I cannot see that the Caprimulgi have 
any close relationship to either.'^
