The Spotted Salamander Amblystoma punctatum PKotograpK from Life bj) Dr. R. W. Shufeldt Among the little used plants which thrive in aquaria, especially if well an- chored, are the native species of arrow- head, SagittJiia (lakes and ponds), and the somewhat rare water fernwort Marsilia, having a four-leaf clover aspect. The latter is best secured from conservatories. The closely related Sal- z'inia, similarly obtained, rarely thrives in the small aquarium, and gradually dies out unless accorded warmth and sunlight. Elodea or Anacharis, the com- mon water weed, and a widely used plant in ac(uaria, has been known to cause the death of snails living in water in which it grows, although in the writer's ex- perience it is apparently harmless to other forms of animal life. Leiuna, known as "Duckmeat," will thrive best under fairly sunny conditions, and is interesting in that it frequently bears on its under surface the siliceous cases of certain minute worms, which may often be seen to emerge from their home and seize animalcules. The larger species of Algae as a rule will only flourish when so entangled with the stems of other plants that the fish find it difticult to penetrate. Of this class of plants, the use of two in aquaria, the stoneworts Nitclla and Chara, should be more generally known. These plants consist of a stem-like body with leaf- like divisions in whorls at regular inter- vals, and have a decidedly rough feeling when drawn through the hand. Al- though they are found in streams con- taining a good deal of li e, they grow well upon a sandy bottom. Isoetes, a botanical curiosity, found in lakes and rivers, will live in the aquarium with a gravel bottom, as well as the common water-moss,. Fontinalis, found along brooks. An animal little known to aquaria, and which will at least exist for some time therein, is SpongUla, the fresh water sponge. It is, however, an aquatic deli- cacy, and should be protected by massing the plants around it. It is found in clear running brooks in circular, con- cave, slightly rough masses of a greenish tinge attached to stones or water plants. Certain forms of colonial Protozoa
