It is to be lamented that the speciric characters 

 given by Linnaeus in the Systema Naturae are too 

 often of very httle use from their excessive brevity. 

 Who can be supposed to be much instructed by 

 such a descriptive character as Vultur re?nigibus 

 nigris, margine ea^teriore, prceter extimas, canis. ? 

 Linnaeus however adds in a note, that the male 

 bird is entirely white, and the female brown. Tlie 

 bird intended by Linnaeus is the Percnopterus of 

 Gesner, not very ill figured at page 193 of that 

 author*s ornithology*, though represented with the 

 head very much retracted, or immersed in the 

 neck-feathers. From the figure it appears to have 

 been a male bird, being white, with the quill- 

 feathers blackish or deep brown : its size, according 

 to the description sent to Gesner, that of a Stork. 



It appears therefore probable that the Rachamah 

 of Mr. Bruce, the Angola Vulture of Mr. Pennant,
