✦ Synopsis

Two Jordanian sandy beaches, one a t the northern end and the other a t the southern end near the Saudi-Jordanian border, were examined during November 1984 to October 1985. Sediments of the South station were made of coarser sand than the North station. I n general, low organic carbon and calcium carbonate levels were found a t both stations. A total of 15839 animals representing 45 taxa were collected from both stations. Mujor differences in community structure were found between the two stations. An avcrilgc density of 7981/m?, 39 tuxa. a n average diversity value of 1.78 and a n evenness of 0.37 were characteristic of the South station. Lower number of taxa (39) and density (818/m2) were found on the North station. However, the average diversity (3.18) and evenness (0.74) were higher. Using the biological index value of MCCLOSKEY (1970), the archiannelid Saccocirrua sp. was the most dominant species a t the South stiltion and the bivalve Tellina perna at the North station.
