Perisesarma Lanchester
''Perisesarma'' is a genus of mangrove crabs in the family Sesarmidae (or Grapsidae in some classifications) predominantly found in the Indo-Pacific. Some 23 species are described as of late 2006, with two from West Africa: ''P. kammermani'' (De Man, 1883) and ''P. alberti'' Rathbun, 1921. They are typically small, semiterrestrial crabs found on the forest floor at low tide. They eat nearly anything they can, and try to eat anything that does not threaten them — including pencils and other objects dropped on the forest floor. The last species of the genus described is ''P. samawati'' Gillikin and Schubart (2004). It can be found in East Africa along with ''P. guttatum'', but its sister species is ''P. eumolpe'' from Malaysian mangroves.

Johannes Govertus De Man
Johannes Govertus de Man (2 May 1850 in Middelburg – 9 January 1930 in Middelburg), was a Dutch biologist. He was assistant curator at the (Dutch for ''national natural history museum'') in Leiden, where he specialised in free-living nematodes and decapod crustaceans, although he also wrote papers on flatworms, sipunculids and, in his dissertation only, vertebrates. His change away from vertebrates disappointed the director of the museum, and de Man left his job there after eleven years. For the rest of his life, de Man worked at his parents' house in Middelburg and later at a house near the shore at Yerseke in the Oosterschelde estuary, relying on his family's private income.
