Abstract
The Amphipoda dealt with in this paper were collected in August, 1906, by Dr. Allen, to whom I am indebted for the opportunity of examining them.The collection contained thirty-five species (belonging to twenty families), of which one only,Tryphosites alleni, is new to science. Five others,Stenothoe richardi, Syrrhoites walkeri, Syrrhoe affinis, Eusirus biscayensis, andRhachotropis rostrata, are recorded for the first time since their original discovery. The geographical range of five species has been considerably extended, viz.Syrrhoe affinis, Tmetonyx similis, Sympleustes glaber, Epimeria parasitica, andLaetmatophihis tuberculatus;the four last forms have not been hitherto recorded with certainty south of Norway.
