A further account of the feeding mechanism of chirocephalus diaphanus

Abstract

During the last ten years Professor Storch and I have published a series of papers on the feeding mechanism of the Branchiopoda. While we agree on the whole and support the views of the earlier workers, Lundblad and Naumann, there are certain fundamental points on which we differ. Last year I published a lengthy descriptive and comparative paper on the subject which summarized the position of the problem as I saw it at the date of its publication, June 20, 1933. Since then two papers have appeared, one by Lowndes (1933) on the feeding mechanism of Chirocephalus , and the other by Eriksson (1934) on the feeding mechanism of the Branchiopoda, in neither of which, unfortunately, is any reference made to my last paper. This would have been of little consequence if these scientists had accepted the views of other workers, but as they both put forward entirely novel ideas the publication of their papers can only lead to confusion in a problem which is already extremely difficult to follow. Lowndes’s paper is relatively short and makes little reference to previous work—in fact, Storch’s work is ignored except for the inclusion of two of his papers in the literature list. The treatment of the problem is that of statement of new ideas with little, if any, argument as to why my views are incorrect and often, and on the most critical points, without any experimental or morphological evidence.
