A. alhifrons. On the contrary the fossil Goose agrees with 

 regard to the short hind toe and the general slenderness of 

 different skeletal parts, neck- and tail vertebrae etc. quite 

 well with A. brackyrhynchus. As it has had its tarsus about 

 10 mm., and its bill (to judge from fragments of the lower 

 mandible) about 12 mm. longer than the corresponding parts 

 of A. brackyrhynchus, has had larger wing-bones, and in ge- 

 neral has been much larger it cannot belong to this latter 

 species but it is suggested that the fossil Goose has belonged 

 to A. neglectus Sushkin which just differs from its relative 

 A. brachyrhynchus in these same characteristics. Fossil re- 

 mains of birds in boulder clay are extremely rare, before 

 this bones of Histrionicus histrionicus found in Halland are 

 the only ones found in Sweden.
