Shows an endwise union of two individuals, a union which occurs commonly and is known as syzygy. D, section through the intes- tinal wall of a meal worm (the larva of a beetle), infected with Gregarina polymorpha (Ham- merschmidt). {Also from Doflein, after Pfeiffer.) Highly magnified. Immature parasites in different stages of development are seen in the epithelium lining the intestine and one mature individual in the lumen of the canal. {A by the courtesy of The Macm,illan Company; B, C, and D by that of Gustav Fischer.) they build one of particles of sand and other foreign objects held together by one of these substances. Interesting members of this class are the Foraminifera, which are mostly marine and which form shells of lime composed of numerous chambers united by openings called foramina, whence the name of the group. They occur in enormous numbers and exhibit great variety. When the shells of dead individuals sink to the sea bottom they form a soft mud or ooze, known as foraminiferous or Globigerina ooze, which, when solidified, becomes natural Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Wolcott, Robert Henry, 1868-1934; University of Nebraska (Lincoln campus).
