living upon or under the skin. Among these might be mentioned, 
for example, the well-known, microscopic, itch mites ( Sarcoptidai) 
and the subcutaneous parasites of birds ( Hypodemdce), usually 
to be found in great numbers, or “ nests/' especially in the fatty 
masses under the base of the wings, adhering to the veins and in 
other portions. Species of all these forms are represented in this 
country, but the material at disposal is insufficient to induce the 
publication of descriptions at present.
