Abstract
Is not the organism photographed under the care of Mr. C. Carus-Wilson (NATURE, May 5, p. 299) far more probably a radiolarian than an insect? The apparent segmentation of the “antennæ” may be due to secondary deposits of silica, and the partition may be caused by the nearness of the plane of section to the inward bulge on the meeting-line of the two chambers of the test. Without an examination of the slide, any suggestion may be rash; but we know little of the Mesozoic types of Cyrtida, and this organism may represent a previously undescribed member of that group. References to descriptions of Cretaceous radiolaria are given by W. Hill and A. J. Jukes-Browne in the Quarterly Journal of the Geological Society, vol. li., p. 600, 1895.
