British Hydracarina – Soar and Williamson – 1925

This is maybe a rather elusive book but I’m proud to own the 3 volumes, with a gold-field end. I bought them on Abe Book. They looks like never  used, as if no one in the Worcester Public Library neither find this interesting.

These books are very interesting. A lot of plates either in color or in black and white illustrates the hydracarina of the United Kingdom.
