IN connexion with the study of South African freshwater fishes, it is of interest to ascertain particulars about Dr. Seeber, after whom two fishes were named by Gilchrist and Thompson. Apparently Dr. Seeber corresponded with these authors about the years 1909–11, but I can obtain no information as to who Dr. Seeber was, where he lived or was stationed, or where he travelled in South Africa. The Medical Register and other local sources have failed, and this request is issued in the hope that one of the many readers of NATURE may have known Dr. Seeber. Any facts bearing on his residence or activities in South Africa will be welcome.
