82 Mr. P. L. Solater on the 



examination, but I find a fifth c. r. present in species of Crax, 

 Penelope, Pipile, and Ortalis. 



XIV. Opisthocomi and XV. Hemipodii. In Opistho- 

 comus, which I have carefully examined, the fifth c. r. is 

 present, as in the Gallinse. It is likewise present in Turnix. 

 I have examined Turnix sykesi. 



XVI. Fulicari.e. In the Rails, so far as they have yet 

 been examined, the fifth c. r. is absent. 



XVII. Alectorides. The Cranes and their allies are 

 not in unison as regards the fifth c. r. In Grus, Aramus, 

 and Eurypyga, according to Dr. Gadow, this remexis absent, 

 but present, according to the same authority, in Psophia, 

 Cariama, and Rhinochetus. I can confirm this as regards 

 Psophia crepitans. 



XVIII. LimicoljE. No true Limicolse have the fifth 

 cubital remex developed, so far as they have yet been ex- 

 amined. In Parra it is also absent. 



XIX. Gavi,e. As might have been expected, the Gavise 

 imitate their close allies the Limicolae in having no fifth c. r. 



XX. Tubinares and XXI. Pygopodes. The same is, I 

 believe, the case in the Tubinares and Pygopodes. The fifth 

 c. r. is absent. 



XXII. Impennes. In the Penguins the remiges are not 

 sufficiently differentiated to enable us to come to any conclu- 

 sion as to the fifth c. r. 



XXIII. Crypturi. In the Tinamous, as in the Gallinas, 

 the fifth c. r. seems to be always present. Mr. Beddard has 

 kindly ascertained for me that this is undoubtedly the case 

 in the following species of this group : — Nothoprocta perdi- 

 caria, Tinamus solitarius, Crypturus noctivagus, and Calo- 

 dromas elegans. Prepared wings of Nothura maculosa and 

 Rhynchotus rufescens now before me show the fifth c. r. well 

 developed. 



Thus the Carinate birds may be divided into three cate- 

 gories as regards the presence or absence of the fifth cubital 

 remex : —
