BIOLOGICAL RESULTS OF THE UNIVERSITY OF MIAMI DEEP-SEA EXPEDITIONS. 102 ON A SMALL COLLECTION OF PORCELLANID CRABS FROM THE CARIBBEAN SEA (CRUSTACEA, DECAPODA, ANOMURA)l ROBERT H. GORE Smithsonian Institution, Ft. Pierce, Florida 33450 ABSTRACT The Research Vessel John Elliot Pillsbury of the University of Miami obtained a small collection of porcellanid crabs during five cruises over a 3-year period from ]968 to 1971 throughout the Caribbean Sea below 200N latitude. The material consisted of 195 specimens divided into 7 genera and 13 species, all of well known littoral or sublittoral forms. While no new species were recorded, several gaps in distributional and ecological knowledge were filled, and a range extension is reported for Petrolisthes cessacii (A. Milne Edwards, 1878) previously known only from a small area on the western coast of Africa, and a single published record from Brazil. INTRODUCTION During a 3-year period from March, 1968 through February, 1971, the University of Miami's Research Vessel John Elliot Pillsbury sampled se- lected areas throughout the Caribbean Sea south of 200N latitude (Fig. 1 and Table 1). Collections were made in an area delineated approximately by the island of Hispaniola to the north, from the Lesser Antilles on the east southward to the vicinity of Surinam and French Guiana in South America, and thence westward along the northern coast of that continent to the Central American land mass and north to British Honduras. The small collection of porcellanid crabs which form the subject of this report was taken at 51 of the stations occupied by the RjV Pillsbury in this area, and consisted of 195 specimens divided among 7 genera and ] 3 species. Of these, Porcellana sayana (Leach, 1820) was the most abundant, with 67 specimens examined; Pachycheles ackleianus A. Milne Edwards, 1880 was next, with 42 specimens. The remainder of the material was made up of well known species which, with one exception noted below, were all pre- viously known from the general area sampled by the RjV Pillsbury. The exception was Petro/isthes cessacii (A. Milne Edwards, 1878) previously known from the Cape Verde Islands, a small area in western Africa, and a 1This paper is one of a series resulting from the National Geographic Society-University of Miami Deep-Sea Biology Program; and Scientific Contribution No. 26, Smithsonian Institution/Harbor Branch Foundation Science Laboratory.

The species is now known in the Caribbean from Trinidad, Tobago, and to the area of Old Providence Is- land off the eastern coast of Nicaragua. The collection as a whole, although small, allowed several distributional and ecological gaps to be filled as well as providing a welcome opportunity to add to our meagre knowledge of the Porcellanidae in the lower Caribbean Sea and the northern coast of South America.
