A history of British star-fishes, and other animals of the class Echinodermata . ut, wanting a ventral disk, appertains rather to the lattergroup than to the former. The Psolinus brevis is abouthalf an inch in length, of an ovate form, with both itsextremities bent upwards. The body is of a pinkish whitecolour, and covered with delicate skin, minutely are five rows of suckers, which range single, six orseven in a row, distant from each other; those of the con-vex or undermost side are very long and always bent, thebending seeming to depend on some peculiarity of organis-ation, and not on the will of the animal. The posteriorpart of the body is very obtuse, but the anterior tapers toa narrow neck. The tentacula are very long, white, anddigitated at their extremities. Internally we find a well developed intestinal tube, butno gizzard ; moderately developed respiratory trees, fewgenital tubes, and one oesophageal sac. The teeth are shortand truncate. In its habits it appears sluggish as regards progressivemotion, but moves about its tentacula <.i;i:\t SEA-cucuMurcit. 209 nOLOTIIURTADJR. PENT ACTJE.
