1st Edition 1892. A very scarce publication which has a presentation inscription from the author to the front cover. Also includes a letter from the author from a later date discussing spiders. The Reverend Octavius Pickard-Cambridge FRS 1828 – 1917 was an English clergyman and zoologist. His main interest was in spiders, though he wrote also on birds and lepidoptera. He became a world authority on spiders, describing a considerable number of new species including the Costa Rican redleg tarantula (Megaphobema mesomelas) and the Sydney funnel-web spider (Atrax robustus). The softback book is good and is in bright condition. Edges lightly rubbed. Light surface loss to paper spine and edges. Contents good.
