In this short paper we list the herpetological specimens collected in southern Surinam (Dutch Guiana) by Mr. and Mrs. Rudolf Freund in November and December, 1961, and include ecological notes made by the Freunds at the time. This area is one from which collections are rare, so that distributional data are generally unavailable. Of special interest is the seemingly common occurrence there, and in adjacent parts of Guyana (formerly British Guiana), of giant specimens of the toad Bufo marinus, of such length and weight to indicate that these animals are the “world's largest toads”. The collecting localities are shown on the outline map (Fig. 200) and available habitat data are given in the species list.
