This large species of puffer fish is found throughout the warm, temperate and tropical seas. It is known from the Cape and St. Helena Island. Three specimens from Vema were collected and presented by Mr. Paterson (SAM 24524). All three were a dirty grey-green dorsally with a white belly. Dorsal, anal and pectoral fins were pale yellow. The pectoral fin has a charac- teristic shape, being broad, rounded on the lower distal corner, and pointed at the upper. The species is capable of very extensive inflation and all three examples examined were much distorted due to this. Zoogeography The relative geographical positions of the islands of Tristan da Gunha, Gough, St. Paul, Marion and Crozet, the Vema Seamount and South Africa are shown in figure 2. Tristan, Gough and St. Paul islands lie on very similar latitudes, whereas the Vema Seamount is roughly as far north of Tristan as the Marion and Crozet groups are south. The Vema Seamount, however, has several fish in common with Tristan whereas the Marion and Crozet groups have no fish in common with Tristan or St. Paul. This, as was suggested by Sivertsen (1945), is almost certainly due to hydrographic conditions, mainly water Fig. 2 Shallow-water areas in the southern Atlantic and Indian Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
