It will be also seen that the wino-s are united bv a nearly seinicu'cular lobe. Tlie empty shell is placed below in order to show its curious structure. Just on the right of the Ilyalea is a smaller creature, with an odd-looking three-pointed shell, hanging as it were from the wings. This is the , a very beautiful and interesting animal, of which ]\Ir. F. D. Bennett writes as follows; " On that part of the body which is ] in the apex of the shell, theie is a small, globular, pellucid body resembling a vesicle, and which at night emits a luminous gleam, sufficiently vivid to be visible even when it is opiocsed to the strong liglit of a lamp. It is the onlv example of a luminous shell-fish I have ever met with ; nor would the luminosity of this species be of any avail, did not the shell possess a structure so vitreous and transparent.
