on Dr. Jerdon's ' Birds of India.' 4-7 



Asiatic Society at Calcutta. Dr. Adams adds {he. cit.), " On 

 the lower Himalayan Range I saw on one occasion a species of 

 Lark or Titlark, of the size of Alauda arvensis ; colour of body 

 was a sandy brown ; but very distinguishing marks were a 

 black throat and streak round the eyes of the same colour. 

 The female was not so distinctly marked." This was, doubt- 

 less, an Otocorys. 



764. Otocorys longirostris. 



I have lately received two pairs from Dr. Jerdon, procured in 

 the desert country north-west of Delhi. This species is distin- 

 guished from 0. penicillata by its larger size, and by the black 

 of the ear-coverts of the male not being continuous with that of 

 the sides of the breast ; the black auricular tufts are also less 

 developed, and the bill decidedly differs in shape. The sexes 

 differ considerably in colouring, and the females are smaller, 

 the closed wings respectively measui'ing 5 inches and 4*5— 4*75 

 inches. The female has no black except on the breast, where 

 the gorget is very much smaller than in the male ; crown, back, 

 and wings dusky-brown, with pale margins to the feathers ; a 

 narrow white supercilium. 0. penicillata was identified by 

 Mr. Swinhoe with 0. alpestris (P. Z. S. 1863, p. 271) ; but 

 Mr. Tristram remarks that Swinhoe's Tientsin specimen is 

 quite different fi'om 0. penicillata, and is, he supposes, the true 

 O. alpestris, and not O. penicillata (P. Z. S. 1864, p. 435, and 

 Ibis, 1866, p. 289). Mr. Tristram has shown also the distinc- 

 tions of O. bilopha (Ibis, 1859, p. 421. I have compared the 

 four Old-World races, and fully recognized their distinctness. 



There is at present insufficient authority for including O. pe- 

 nicillata (no. 763) as an Indian bird. 



766. Alauda triborhyncha. 



A specimen lately received from Dr. Jerdon thus marked by 

 him, differs in no respect that I can perceive from the European 

 A. arvensis, not even in the proportions of its primaries ; and 

 the closed wing measures 4*5 inches. Mr. Gould, however, 

 refers it to A. moreatica, Bonap., in which I fail to perceive 

 sufficient distinction.
