Norman says, " Has Polyclieles such organs?" Most decidedly it has; and I gave a distinct figure of one in the October number of the ' Annals.' But why did not the Rev. A. M, Norman examine the specimens in his possession ? he would not then have had to write, " it were to be wished that Mr. Bate had lettered the figures of the plate to have made them more ; Had I thought there would have been any difficulty in understanding them I would; but I felt that I was writing for advanced carcinologists, and therefore thought that the references would be unnecessary*. Most certainly the eye I described is not on " the base of the peduncle of the inner antennse," which, from its situation, can- not be the homologue of the true eye. That which I describe as being the eye is homologically the same as that found in Astacus, Cancer, &c. * I see that, in the plate alluded to, fig. 1° has no reference; it is the fifth pereiopod of Pentacheles Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original London, Taylor and Francis, Ltd
