STEJNEGER | ANIMALS AND PLANTS OF NORWAY 473 
market days and was surprised to find how many were without a 
trace of these burrs. In the majority of the animals there were 
small, often very minute vestiges of callosities, and it was inter- 
esting to note how closely their smaller or greater size corresponded 
to the greater or lesser approach of the other characters to the 
type of the pure-bred horse. These were all common farm horses 
without pedigree, and the amount of admixture of foreign blood 
was a matter of conjecture. Only in one instance was I able to ex- 
amine an authentic hybrid between alleged pure-bred parents. The 
specimen is now mounted in the Bergen Museum. It is a mixture 
of Nordfjord horse and Gudbrandsdal horse, and the longest diam- 
eter of the posterior callosities measures 23 mm. 
In the museum at Bergen I found another highly interesting 
specimen which has a decided bearing on the question. I am, there- 
fore, going to give some details derived from an examination, for 
the privilege of which I am greatly indebted to the curator of the 
division of vertebrates, Mr. James A. Grieg. 
The specimen is one of the last survivors of a white variety of 
the fjord-horse formerly more common in Nordland and, more 
especially, on some of the Lofoten islands. A photograph of the 
mounted specimen (pl. LxIx, 2) shows what an extraordinarily 
long-haired creature it is, exceeding that of the Celtic pony figured 
by Ewart (p. 249, fig. 34; p. 593, fig. 5), the hair being distinctly 
curly, especially on the legs. Needless to say, the hind chestnuts 
were absolutely lacking! 
The most interesting part of this specimen, however, is its skull. 
Unfortunately, we have no description of any skull from the type 
locality of Equus celticus, but Ewart’s hints as to the relative width 
of the forehead and the length of the facial portion of the two horses 
indicate an agreement with the results which I have obtained. 
The following measurements of the skull of the Lofoten horse 
are only those regarded by Tscherski as of particular importance.
