During the course of investigations on the genus
Arenicola it became necessary to determine the characters and systematic position of
A. loveni Kinberg, and to ascertain if this is a valid species or if, as suggested by several writers, it should be merged with
A. marina. As a decision regarding the validity and position of the species could be reached only after examination of the type, I applied to Professor Théel for the loan of this specimen, preserved in the Riksmuseum, Stockholm. I beg to express to him my sincere thanks for so readily entrusting to me this interesting and valuable specimen and also for permitting me to make an inspection of its internal organs, without which a definite conclusion regarding the position of the species could not have been attained. My examination of the type specimen showed that the species
A. loveni Kinberg is a valid one. On ascertaining this I wrote to Professor J. D. F. Gilchrist, inquiring if, during his marine investigations, he had found specimens of
Arenicola on the shores of South Africa. In reply he sent to me, in July, 1909, four specimens taken in Saldanha Bav, which prove to belong to Kinberg's species. He has since (October, 1910) sent to me examples of
Arenicola dug from the sand in Table Bay and in Lüderitzbucht (Angra Pequeña), and two specimens found cast up dead, after a storm, on the shore of False Bay. I beg to thank Professor Gilchrist for so generously placing these specimens at my disposal.
