CALCEOLARIA CALL A. 



Thus, it is associated with nearly all the metallic 

 minerals contained in gneiss, mica-slate, clay-slate, 

 and porphyry ; seldomer in granite, more frequently, 

 again, in greywacke, and along with cobalt and 

 copper-ores in the oldest secondary limestone. Veins, 

 almost entirely composed of calcareous spar, abound 

 in the newest limestone formations ; and it is a 

 common mineral, either in veins, or in contempo- 

 raneous masses, in the various rocks of the secondary 

 or flcetz-trap series. 



CALCEOLARIA (Linnaeus). SLIPFERWORT, a 

 handsome family of flowering plants, natives of Chili. 

 Linnaaan class and order, Diandria Monogynia; natu- 

 ral order, Scrophularince. Generic character : calyx 

 four cleft, corolla gaping and inflated, capsule two- 

 celled and four-valved. This genus has received its 

 name from the remarkable shape of the inflated 

 corolla resembling a shoe or slipper. Some of them 

 are tender annuals', others deciduous under-shrubs. 

 Two species have been long known in British gardens, 

 but a great accession has been made within the last 

 twelve years. From these last many varieties have 

 been obtained by cross impregnation, so that they are 

 now numerous. Above forty sorts are now cultivated 

 and highly ornamental to the flower borders in summer, 

 and greenhouse in autumn. Some of them will stand 

 through the winter if placed in pots and kept in a 

 cold frame ; or if, in the open borders, they be suffici- 

 ently protected against severe frost. They, however, 

 flower much better by having a good situation in 

 the greenhouse or conservatory during winter. 



All the annual species and varieties should be sown 

 raised and treated exactly like what are called "ten- 

 der annuals," such as the balsam, cockscomb, amaran- 

 thus, &c., pricked out from the seed-pans into very 

 small pots, and repeatedly shifted into larger and 

 larger up to twenty-fours, in which they may flower. 

 Such of them as are biennials, as the C.Jloribunda. are 

 best sowed in September and treated like greenhouse 

 plants. The perennial species are propagated by 

 division of the roots, and by cuttings and seeds, so 

 are also the half shrubby species. Seeds sown as 

 they ripen flower in the following summer ; but 

 not so strong as if sown in the spring, and not allowed 

 to flower till the second summer. 



CALDASIA (Willdenow). An ornamental hot- 

 house annual belonging to the fifth class of Linnaeus, 

 and natural order Polemoniacece. It has pretty blue 

 flowers, and is propagated by cuttings. 



CALEA (R. Brown). A genus of hot-house ever- 

 green shrubs, natives of the West Indies. Linnaean 

 class and order Syngcnesia JEqualis; natural order, 

 Composite. Generic character : involucrum imbri- 

 cated, receptacle chaffy, pappus hairy. The leaves 

 are entire, and the flowers are yellowish purple, 

 growing in terminal or axillary heads. 



CALEACTE (R. Brown). A syngenesious plant 

 found on the sea shore about Vera Cruz. This plant 

 was formerly called Solidago urticifolia. 



CALEMPELIS (D. Don). A perennial green- 

 house climber from Chile, formerly called Eccrcmo- 

 carpus by Ruiz and Pavon. Linnaean class and order, 

 Didynatnia Angiospermia ; natural order, Bignoniaceee. 

 Generic character : calyx bell-shaped, limb four or 

 five parted, spreading ; corolla tubular, upper part 

 swollen, contracted at the mouth ; limb short, in five 

 reflexed lobes ; stamens included ; anthers free, 

 fleshy and parted at bottom ; stigma two-plaited ; 

 seed-vessel oval, compressed, one-celled, two-valved ; 



seeds with membranous wings. This is a showy 

 green-house plant, and seen in most collections. 



CALEPINA (Adanson). A cruciferous annual 

 plant heretofore called Myagrum iberiodes. It is a 

 native of the south of Europe. 



CALEPTERYX (Leach). A genus of Dragon 

 Flies. See AGRIONID.-E. 



CALEYA(R. Brown). Tuberous rooted plants 

 from New Holland. Linnaean class and order Gynnn- 

 dria Monandria. Natural order OrchideeE. Generic 

 character : calyx of five sepals nearly equal, and 

 narrow ; labellum clawed behind ; lamina peltate, 

 caved ; columna naked, somewhat dilated ; anthers 

 terminal ; pollen in two masses. 



CALIGIDES (Latreille). A family of parasitic 

 Crustacea, belonging to the section Entomostraca 

 Siphonostoma, or those which have the mouth formed 

 into a sucker. The body is covered by an oval or 

 sernilunar shield, flattened above, with twelve legs, 

 the four last pairs of which are feathered and pinnate, 

 being admirably formed for swimming. The tail is 

 more or less elongated and exposed, and terminated 

 by two appendages. This family comprises only two 

 genera, Arguhis and Caligus. The first of these is 

 established for the reception of a small but very 

 curious (British) animal found upon various small 

 fresh-water fish, upon the blood of which it subsists, 

 sometimes to the destruction of its victim. It is the 

 Monocidus Foliaccus of Linnaeus, and its natural 

 history and structure, in the different stages of its 

 existence, have been detailed by the younger Jurine 

 in the most satisfactory manner in the seventh volume 

 of the Annales du Museum d'Histoire Naturelle. 

 The insect is nearly a quarter of an inch long, and 

 the body is covered with a large flattened, and nearly 

 circular and transparent shield (through which the 

 organs of the under side of the body may be seen), 

 having two eyes near the front margin. It is notched 

 behind, discovering the abdomen, which is extended 

 beyond it to a short distance. The month is formed 

 for suction. There are four small inferior antennae. 

 The legs are of singular construction ; the first pair 

 are large and short, and shaped somewhat like a cup, 

 since it is by these organs, which probably act like a 

 cupping machine, that the insect attaches itself to 

 small fish. The four hind pairs of legs are formed 

 for swimming, each being terminated by two long- 

 feathered filaments. The young resemble their pa- 

 rents in form, though their locomotive organs are 

 very differently constructed. The other genus, Cali- 

 gus, is destitute of the large cup-shaped feet, the 

 anterior pair being hooked. The tail is long, and 

 terminated by two very elongated processes in the 

 females, of which the use has not yet been determined. 

 These animals are termed fish-lice, being parasitic 

 upon various kinds 'of fishes. The genus has been 

 subdivided into several sub-genera by Leach and 

 Latreille. 



CALL A (Linnaeus). A genus of perennial her- 

 baceous plants, natives of different parts of the world. 

 Linnaean class and order, Heptandria Monogynia ; 

 natural order, Aroidcce. Generic character : spatha 

 of one leaf ; spadix cylindrical, and covered with 

 styles and stamens ; antherae twinned and two-valved ; 

 stigmas sitting ; fruit a berry containing strong-scented 

 seeds. These plants in habit resemble the arums. 

 The Callu JEtkiopica, now called Richardia JEthiopica, 

 is one of our commonest green-house plants, and very 

 often seen ornamenting cottage windows. Its arrow-
