Dibranchiata
an order of cephalopods characterized by the possession of two gills only, and by the fact that the shell, if external, as is rarely the case, is never chambered. It includes the cuttlefishes, squids, and paper nautilus. The order contains two sections, octopoda and decapoda.
DICE (plural of die), small cubes of ivory marked on their sides with black dots, from one to six. The points on the opposite sides of the dice should always sum seven-i. e., ace should be opposite to six (pronounced size); deuce to cinque (pronounced sanke); and trey to quatre (pronounced kater). The invention of dice is attributed to Palamedes (circa 1244 в. c.).
