In full-grown larvae (50mm or a little more in body length) of Malacosoma neustria testacea Motschulsky, extirpation of either the prothoracic or the mesothoracic ganglion results in a marked distension of the body within about 24 hours. The body becomes fully stretched, attaining about 70mm in length. The larvae become almost unable to move, except that they show a continuous biting and swallowing movement of mouth-parts. The alimentary canal is filled with air thus swallowed. When punctured by needle, the air escapes from the alimentary canal and the body immediately becomes reduced in size (see Figs. 1 and 2). After removal of the subesophageal ganglion or of the brain, the mouth-parts become immobile. In these larvae, extirpation of the prothoracic ganglion no longer causes the distension of the body. If the mouth and anus are closed with paraffin immediately after removal of the prothoracic ganglion, no distension of body can be observed. It is obvious, therefore, that the body distension following removal of the prothoracic ganglion is largely attributable to an abnormal intake of excess amount of air into the alimentary canal. Extirpation of the prothoracic ganglion appears to bring about a failure of a proprioceptic inhibitory mechanism. In younger larvae, mature larvae or prepupae no distension of body takes place after removal of the prothoracic ganglion. In the silkworm (Bombyx mori, L., J-122×C-115) deprived of the prothoracic ganglion, the distension is very slight.

Cellular composition of the lens of the dorsal eye in Onchidium verruculatum (Opisthobranch, Gastropoda) was investigated by light microscope and the photoresponsiveness of the lens cells and their identities were examined by means of a fluorescent dye microelectrode technique. A pear-shaped lens located in the center of the dorsal eye was composed of several lens cells and ensheathed entirely with connective tissue. Number, shape, size and arrangement of constituent cells were considerably varied in individual lenses. In most lenses, an upper principal part and a lower accessory part could be distinguished, each of which was composed of a group of lens cells and surrounded by glia-like cells. The principal part with a flat bottom contained 1-8 cells and occupied more than half of the lens, beneath which the accessory part containing 0-9 cells adjoined and formed the spherical bottom of the whole lens. The size of the lens was almost linearly related to that of the dorsal eye itself, and it was noted that the larger the lens, the more complex the cell composition. In 63% of the lenses, the principal part was formed by a single large lens cell. Occasionally, free lens cells occurred outside the lens proper. All the lens cells, independent of their location, were provided with rhabdomerric microvilli and responded to light with a characteristic pattern of slow depolarization. It was suggested that lens cells in the Onchidium dorsal eye play double roles, that of a photoreceptor individually and of a dioptric apparatus en masse.
