Note: Bakus, 1966, described this species from Washington and noted the presence of pore sieves which do not occur in Lissodendoryx. Measurements and illustrations are those of de Laubenfels. Cf. 142B and page 166A. This species in California needs to be thoroughly reviewed. While the "form" presented in 142B is the common one seen in California, it may be a different species from that described by de Laubenfels.
