Recently a small but very interesting collection of prawns belonging to the genus Macrobrachium was submitted to me for study by Dr. Ricardo Zariquiey Alvarez of Barcelona. These prawns originate from the Spanish possessions on the west coast of Africa. Four species are represented, one of them is new. For ,cornparison I examined West African material of the genus Macrobrachium present in the collections of the Rijksmuseum van Natuurlijke Historie at Leiden and of the Zoological Museum at Amsterdam. The present paper in the first place deals with the material from Dr. Zariquiey's private collection, while also notes on one new and one llttle known species, preserved in the Amsterdam Museum, are given.
