"When the volumes of 'Contributions to a science of nematology' were assembled ... the two plates of mononchs (p. 185 to 188 inclusive) could not be found. In order to make the volumes complete for binding, reproductions of these plates were made, by lithoprinting ..." cf. unnumbered leaf inserted after p. 184.
