Swammerdam, the Dutch scientist, was the first author who took notice of any of the Daphniae. In his Historla Insectorum Generalis, 1669, he gave a description of a species of Daphnia, which resembled Daphnia pulex and which he named Pulex arboreus or arborencens. He stated that its beak was slender and pointed, and was used for drawing up food. He called the second antennae arms and described their motion as three-fold—rectilinear, unequal, and gyratory. He asserted that there were two eyes which seemed to be joined together. Merrett mentioned Daphnia in his Pinax rerum Britannicarum, published in 1677.
