The Scyphophori, Haplomi, and Xenomi —_207 
This animal, formed like a mud-minnow, reaches a length 
of eight inches and swarms in the bogs and sphagnum swamps of 
northwestern Alaska and westward through Siberia. It is found 
in countless numbers according to its discoverer, Mr. L. M. 
Turner, ‘“wherever there is water enough to wet the skin of 
a fish,’ and wherever it occurs it forms the chief food of the 
natives. Its vitality is most extraordinary. Blackfishes will 
remain frozen in baskets for weeks and when thawed out are 
as lively as ever. Turner gives an account of a frozen individual 
swallowed by a dog which escaped in safety after being thawed 
out by the heat of the dog’s stomach.
