[unknown place and publisher], after 1901. Two copies in two. 8vo (21.0 x 13.5 cm). 31 pp. Uniform early 20th-century (contemporary) half cloth over marbled boards.

Two copies of an apparently very rare work on Dutch butterflies (listing 983 species in all) of which we could not find any information whatsoever. The pages are numbered (except the first and last, and there is no title page. In the catalogue of the Nederlandse Entomologische Vereniging (NEV), the following is present: [Oudemans, JTh ?, ca. 1898] "Lijst van Nederlandsche Lepidoptera, benevens de als vermoedelijk Nederlandsch aan te merken soorten, gerangschikt volgens Snellen's Vlinders van Nederland en genummerd volgens Staudinger en Wocke's Catalog (Dresden, 1871). Mede geschikt ter ruiling, in welk geval de aangeboden voorwerpen vóór en de gevraagde achter den naam moeten worden aangeduid door het plaatsen van een punt ...". These copies are very similar, however, the list ends with "Genummerd volgens Staudinger en Rebel 1901 met de bladzijden van Snellen, Microlepidoptera". These copies also (as described above in Dutch for the work attributed to Oudemans} with pencilled dots in front of the species numbers, and with some random marginalia. One copy interleaved, with many additional annotations, neatly written in ink on the blank leaves, and on the printed pages (mostly taxonomical or nomenclatural corrections). Boards much rubbed and spines tender, otherwise good. Not in Horn-Schenkling II.
