Fifth Cubital Remex in the Carinatse. SI 



C r. appears to be always present. I have examined Rham- 

 phastos, Selenidera, Aulacorhamphus, Indicator, Megalama, 

 and Xantholcema, and many genera of Cuculidse*, as also 

 Curythaix and Schizorhis. Dr. Gadow's researches, so far as 

 they go, show the same result, and he also gives it as present 

 in Trogon. 



Therefore, as a rule, we may say that the Picarians are 

 quincubital, except the families Cypselidse and Alcedinidse, 

 in which some forms are aquincuhital. 



III.-X. Psittaci, Striges, Accipitres, Steganopodes, 

 Herodiones, Odontogloss.e, Palamede^e, and Anseres. 

 In all members of these eight classes yet examined the fifth 

 c. r. is wanting. Dr. Gadow's tables agree with my obser- 

 vations on this subject. Wray (see above, p. 77) has stated 

 that the fifth c. r. is present in Phosnicopterus. But this is 

 certainly not the case in examples of two species of this 

 genus which I have examined (P. anti quorum and P. igni- 

 paUiatus), and I believe that Wray was in error on this 

 point. Dr. Gadow agrees with me in registering Phoeni- 

 cupterus as having no fifth c. r. 



XL Columbje and XTI. Pterocletes. In the Columbre, 

 as also in Pterocles, I believe the fifth c. r. to be absent. This 

 is also stated by Dr. Gadow, but more observations are re- 

 quired upon these birds. 



XIII. Galling. In the typical Gallinee generally the 

 fifth c. r. is fully developed (see illustrations of Phasianus, 

 above, p. 78). But this is not, perhaps, the case in Mega- 

 podius, where Mr. Beddard found it absent in a specimen of 

 Megapodius rubrifrons. The Cracidse likewise require further 



* The species of Cuculidfe examined were : —
