tity in those stomachs containing the Physe. Attached to the 
fauces of several individuals were found sometimes as many as

food-remains of any sort, but was completely filled with clusters 
of this nematode hanging from its walls. ;

The Turkey-Skull.— Dr. R. W. Shufeldt has recently pub- 
lished the results of his comparisons of the skulls of wild and 
domesticated turkeys, undertaken with a view of noticing the 
changes brought about by domestication. His results in brief are : 
1. In the wild bird the nasals fuse with the frontals, but in the 
domestic bird they are separated by a persistent suture. — 
2. Inthe wild turkey the cranio-frontal region is wider and 
More concave than in the tame variety. + 
3. The parietal prominences are more evident, and the median 
‘ longitudinal from these to the occipital ridge is shorter m the 
wild than in tame birds. 
= 4 The occipital area in the wild turkey is cordate, the apex 
: Upwards; in the tame turkey it is roughly semicircular. 
= „ 5. The intraorbital septum is entire in the wild bird, perforate 
T in the tame, . : 
2 6. The pterygoids are longer and more slender in wild than in 
1 tame varieties. ; 
7. The skull is denser and thicker, as well as smoother, in the
