The reproduction of these Uttle animals is by a simple division of the body into two when they have grown large enough to feel cumbersome as single individuals. Although cysts are formed for protection against. Fig. 41. Common shapes of Endamceba gitigivalis, from human mouth, x 650. (After Bass and Johns.) an unfavorable environment, no multiplication within the cysts has been observed such as occurs in Endamceba coli or E. histolytica. The cysts, which are rarely found, usually measure from eight to ten jj, (^^Vtt to Wiss of an inch) in diameter, and are perfectly spherical with a thin wall. Some investigators have suggested the possible identity of E. gingivalis and E. histolytica, but, as pointed out by Craig, the sluggish movements, small nucleus, absence of certain changes in form of the nucleus observed in the dysentery ameba, formation of cysts with a single nucleus, inability to produce dysentery when swallowed and other characteristics all indicate that without doubt the mouth ameba is quite distinct from the in- testinal amebse. Other species besides E. gingivalis have been found in the human mouth, but little is known about them. E. kartulisi is large with very distinct ectoplasm; it is said to occur only rarely. Recently Craig has described another ameba of small size, which he has provisionally named E. confusa on account of the likelihood of confusing it with small specimens of E. gingivalis..
