Extract

Notice is given of the presence of a previously un-reported oedicerotid amphipod species, Pontocra tes arcticus Sars, in the shallow sublittoral zone of the sandy beach at Kames Bay, Millport (Scotland). Distinguishing features from P. arenarius are the parallel-sided second coxal plates, strongly deflexed narrow rostrum and lack of sternal dark pigmentation patterns in both sexes. A key to the three species in the genus is provided.
