Producer "The distinctive methods of locomotion of a number of true worms in their natural habitats are excellently portrayed. Oligo- chaetae are represented by Lumbricus and Tubifex. In the Polychaeta, we see the free-living Nereis and Nephthys, the paddleworm, Phyllodoce, the burrowing lug-worm, Arenicola, and the tube-dwelling Sabella and Spirula. The second main group of Annelida is represented by Hiru- dinea, or leeches; the Hirudo, or medicinal leech, and the Lesser Pond Leech being shown. One species is shown in the Tro- chosphere or larval stage as a free-swim- ming organism moving with the aid of its cilia. Throughout, attention is drawn to adaptive structures in action. A most informing and enjoyable record of mere worms in their several haunts. . . [Recom- mended fon zoology and biology classroom instruction for students of 16 and up- wards." British film inst.

DISTRIBUTORS 16mm: Geo "An interesting film dealing with the insect which is commonly known as the seventeen-year locust. The film follows in pictured detail, with a lecture explaining each step, the life cycle and history of this unusual insect. Through the use of time-lapse photography the shedding of the skin in several different stages of growth is shown. The final transition from the pupal stage to the winged insect is clear- ly explained and picturized. The egg-lay- ing process is explained, and the young cicadas are shown hatching from the eggs and dropping to the ground to begin their larval stage underground. The unusual treatment of this film and the interesting nature of its subject make it suitable for all audiences." Georgia el-Jh-sh-c Glow-worm. (Secrets of nature ser.)

"The glow-worm hatches out under a stone, and is at first a long queer-look- ing grub equipped with a kind of rosette of fingers which it uses for pulling itself up grass stems, or for washing its face and its innumerable legs. The male glow- worm is a handsome winged creature but the female is a plain little grub. She has however a lamp of phosphorus just above her tail with which she attracts the male."
