This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1906 edition. Excerpt: ...vesicles numerous, scattered. Trichocysts not evident. Length of body, 400 microns. (Fig. 103, PI. XIII.) The organism as described above resembles, in the character of its nucleus, Loxophyllum meleagris MiilI. The nucleus in some individuals has been observed to be band-like while in other specimens as many as eight disconnected oval bodies are present, the latter probably representing the mature phase of the organism. Crenulation of the dorsal border has, however, not been made out in the Iowa species, nor has the presence of trichocysts been evident. Found in the bacteria-laden film of water at the surface of pond water infusions. Reproduction is by transverse fission. DILKPTUS Dujardin. Very elongate, with a narrow anterior region, neck-like and flexible, at the base of which is the mouth. Nucleus moniliform. Contractile vesicles numerous, in a dorsal row. Trichocysts present in the neck-like region. Dileptus Gigas C. & L. Body greatly elongate, somewhat compressed, often with a pointed tail-like prolongation. Anteriorly the body is produced into a long, flattened, neck-like region, very flexible and slightly extensile. Oral aperture at the base of the neck, often a prominent hump or shoulder indicating its position. Pharynx short. Nucleus moniliform, extending nearly the length of one side of the body. Contractile vesicles numerous, arranged in a dorsal row nearly the whole length of the body. Trichocysts on the ventral surface of the neck. Length of body, 500-800 microns. (Fig. 106, PI. XIV.) This species is one of the most elongated free-swimming species of Protozoa common to this state. The organism is carnivorous in its food habits, smaller animalcules usually being captured by means of the trichocysts and pressed into the oral aperture...
