THE SPECIES OF BEAN-GEESE. 43 



of this Goose, taken from a bird which he had the opportunity of exa- 

 mining. 



Naumann very carefully explained (Naumannia, 1853, p. 5, pi. i.) the 

 differences between this species and A. arvensis and figured the bills of 

 both. Mr. Frohawk has recently (Zoologist, 1903, p. 41, pi. ii.) also 

 given us an account of the two species, and from these sources I am 

 able to give some particulars of A. segetum. 



It will be seen that the bill of A. segetum (fig. 2) is of a different 

 shape from that of ^4. arvensis, being much shorter, but at the same time 

 of the same depth at the forehead. In A. segetum the combined length 

 of the culmen and nail is considerably less than four times the length of 

 the nail itself. In A. arvensis, it is considerably more. The pale parts 

 of the bill of A, segetum are orange-yellow, but this colour appears to 

 be confined at all ages to a ring or band behind the nail and does not 

 spread over nearly the whole bill as it does in A. arvensis when old. 

 Mr. Frohawk states that the number of teeth on the upper mandible of 

 A. segetum is about twenty, whereas in A. arvensis the number is 

 about twenty-eight. I do not know if this character will prove of any 

 value. The two species are of much the same size and colour. 



It will be noticed that the bills of A. segetum (fig. 2) and A. oatesi 



(fig. 8) appear to be very similar, but it must be remembered that the 



former bird is a large Goose, the latter a small bird like A. brachy- 



rhynchus. 



3. Anser brachyrhynchus, Baillon (fig. 3). 



The Pink-footed Bean-Goose. 



This Goose has such a small bill that it is hardly possible to confound 

 it with any other species. A considerable number of birds in the 

 British Museum from Holland have the length of the bill varying from 

 1*6 to 1*8 inches. The colour, in life, of the pale part of the bill is a 

 beautiful rosy-pink, crimson-pink or carmine, and this spreads back with 

 age under the nostrils, almost to the gape. The wing measures from 

 16*3 to 17*5 inches. This species when in good plumage has the 

 mantle of a rather bright fulvous colour and the greater part of the 

 wing a fine grey. The feet appear to be coloured like the pale parts of 

 the bill. 



This is the species which has for very many years figured as the sole 

 Bean-Goose of India, and in recent years Mr. E. C. Stuart Baker has 

 confirmed the occurrence of this species in the North-East of India.
