specimens received from Mr. H. H. Keays, by wliom it was 

 made at Inca Mine, in S.E. Peru (lat. 18° 31' S., long. 

 70° W., alt. 6000 feet) : Chlorochrysa faUjentissima, Malaco- 

 thraupis castaneiceps, Euphonia xanthugastra brunneifrorts , 

 Chlorospingus flavigularis parvirostris, Ochthceca keaysi, and 

 Terenura xanthonota. The Chlorochrysa is apparently the 

 same as that described and figured in this Journal (Ibis, 

 1901, p. 716, pi. XV.) by Graf. V. Berlepsehand M. Stolzmann 

 as C hedmg(e ; and if so, Mr. Chapman's name (August 1901) 

 will have priority. 



46. Clark on the Affinities of the Humming-birds. 



[Are Iluruming-birds Cypseloid or Caprinuilgoid ? 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 Cypselidoe and Caprimulgidfe, 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 pteryloscs 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."
