p. 471 (i856, ex Blyth MS.) A. raytal. 



Confined to the Indian peninsula, and not represented in Africa. 



Genus 6. Rhamphocorys. Type. 



Rhamphocorys, Bp. C. R. xxxi. p. 423 (1850) .... JR. clot-bey- 

 Ieraplerhina, Desmurs et Lucas, Rev. et Mag. de 



Zool. 1851, p. 24 R. clot-bey. 



Appears to be rather an exaggerated Ammomanes, and not to have 



any great affinity with Melanocorypha. 



Genus 7. Ala u da. Type. 



Alauda, Linn. S. N. i. p. 287 (1766) A. arvensis. 



Genus 8. Calandrella. Type. 



Calandrella, Kaup, Natiirl. Syst. p. 39 (1829) C. brachydactyla. 



Corypkidea, Blyth, J. A. S. B. xiii. p. 960 

 (1844) C brachydactyla. 



Calandritis, Cab. Mus. Hein. Th. i. p. 122 

 (1850) C. brachydactyla* . 



Differs from Alauda chiefly in its thicker bill, otherwise very closely 

 allied. Distinguished by larger and more sharply pointed wings. 



* I presume, from the general references of ornithologists, that the type of 

 Calandritis is the Short-toed Lark, as Cabanis proposed to supersede with this 

 term the unclassieal titles of Kaup and Blyth ; but were the first species men- 

 tioned of each genus to be regarded as the type, then A. cmetea would be the 

 type of Calandritis, which would thus supersede my genus Tephrocorys (vide 

 i'tifra, p. 033).
