Used synonymously with Enceplu.Ua, to designate those Mollusca which possess a distinct head. Cephalopoda (Gr. ke/Aale; and poda, feet). A class of the Mollusca, com- prising the Cuttle-fishes and their allies, in which there is a series of arms ranged round the head. Cephalothorax (Gr. kephale; and thorax, chest). The anterior division of the body in many Crustacea and Arachiida, which is composed of the coalesced head and chest. Cere. The naked space found at the base of the bill of some birds. Cervical (Lat. cervix, neck). Connected with the region of the neck. Cestoidea (Gr. kestos, a girdle). An old name for the Tmiiada, a class of Intestinal Worms with flat bodies like tape (hence the name Tapeworms). Cestraphori (Gr. kestra, a weapon ; pkero, I carry). The group of Elasmo- branchii represented at the present day by the Port Jackson Shark. Cetacea (Gr. ketos, a whale). The order of Mammals .comprising the Whales and Dolphins. CHiETOGNATHA (Gr. chaite, bristle ; gnatkos, jaw). An order of the Anarlhro- poda, comprising only the oceanic genus Sagitta. Cheiroptera (Gr. cheir, hand ; pteron, a wing). The order of Mammals com- prising the Bats. Chelae (Gr. chele, a claw). The prehensile claws with which some of the limbs are terminated in certain Crustacea, such as the Crab, Lobster, &c. Chelate.

Little sacs which contain pigment-granules, and are found in the integu- ment of Cuttle-fishes. Chrysalis (Gr. chrusos, gold). The motionless pupa of butterflies and moths, so called because sometimes exhibiting a golden lustre. Chylaqueous fluid. A fluid consisting partly of water derived from the exterior, and partly of the products of digestion (chyle), occupying the body-cavity or perivisceral space in many Invertebrates (Annelides, Eckino- derms, &c), and sometimes having a special canal-system for its conduction (chylaqueous canals). Chyle (Gr. chulos, juice). The milky fluid which is the result of the action of the various digestive fluids upon the food. Chylific (Gr. chulos, juice [chyle]; and Lat. facio, I make). Producing chyle. Applied to oue of the stomachs, when more than one is present. The word is of mongrel origin ; and chylopoietic is more correct. Chyme (Gr. chumos, juice).
