Three species of Mysidacea (Crustacea) from Surinam

This report is the eighth in a series of papers (Brattegard, 1969, 1970a, 1970b, 1973, 1974a, 1974b, 1975) dealing with Mysidacea (Crustacea) from shallow water in the tropical and warm-temperate areas of the western Atlantic. Hitherto unpublished material of shallow-water mysids collected in brackish water and fresh water in Surinam, South America is presented in this paper. I gratefully acknowledge the cooperation of the collectors, Dr. P. Wagenaar Hummelinck of the Zoölogisch Laboratorium, Utrecht, Nederland and Mrs. M. P. Panday-Verheuvel of the Surinam Forest Service, Paramaribo, Surinam. The type material will be deposited in the United States National Museum of Natural History, Washington, D.C. (U.S.N.M.) and the rest of the material will be deposited in the Rijksmuseum van Natuurlijke Historie, Leiden, Nederland. I am greatly indebted to Dr. J. B. L. Matthews for help with the manuscript. ?Antromysis sp. (fig. 1) As the following brief description is based on only one partly damaged berried female, there is hardly sufficient basis for the erection of a new species until further material comes to hand. The specimen, a berried female with 2 embryos in the brood pouch, was collected by Dr. P. Wagenaar Hummelinck at stn 923 on 15 October 1968, in a brackish-water (700 mg Cl-/1) ditch at Domburg, SE of Paramaribo, Surinam. Other mysid species in the same sample were Diamysis americana and Parvimysis almyra sp. nov. General form moderately slender.
