COraman- ifaUi. Irnni Cora, or Ci'ilu. name of a people +
iiuifnlu, circle, kingdom). A vaguely detined region of British India, comprising the portion of the eastern coast of iladras lying between Point Caliniere, in about latitude 10° 17' N., and the mouths of the Kistna, in about latitude 15° 40' N. (Map: India, D 6). The name is some- times applied to the whole of the west shore of the Bay of Bengal. The coast has numerous in- lets, but possesses no safe harbors. Shijis are compelled to anchor several miles off the coast. The districts along the coast were the battle- fields for supremacy in India between England and France in the eighteentli century, COROMANDEL GOOSEBERRY.

In architecture, the most pro- jecting upper part of the classical cornice ; also used to designate the drip, or lower member of the cornice above the bed-molding and below the cymatium. (See Entablature.) The term corona is also applied, especially by ecclesias- tical writers, to the apse or semicircular termina- tion of the choir, as in the case of 'Becket's crown,' at Canterbury. Corona is also applied in ecclesiastical nomenclature to a chandelier, in the form of a crown or circlet, suspended from the roof of a cliurch, or from the vaulting of the nave or chapels, to hold tapers which are lighted on solemn occasions. A famous mediaeval ex- ample is at Saint Jliehael, Hildesheim. CORONA. In plants, a word applied to any crown-like appendage at or near the summit of an organ. It is usually restricted, however, to appendages which occur in connection with corol- las. For example, in the species of Silene and allied forms, members of the pink family, there is a two-lobcd outgrowth at the junction of the claw and blade of each petal. Taking the petals together these outgrowths form a ten-lobed crown at the base of the blades. In the passion-flowers there is a very conspicuous corona consisting of many rows of filamento)is outgrowths. Similar outgrowths are found in the flowers of other families, but are most notable in sympetalous corollas, where they form folds or projections in the throat, as in oleander, various borages, etc. In the several species of Narcissus the corona which rises from the throat of the corolla is often very conspicuous. In all cases these appendages are outgrowths from the inner face of the petals, and it has been suggested that they are the equivalents of similar outgrowths from the inner face of grass-leaves, at the juncture of the blade and sheath. In this latter case the appendage is called a 'ligule.' ConOS.l (/)) OF NARCISSUS. CORONA BO'REA'LIS (Lat., Northern Crown). A small and bright constellation near Hercules. CORONACH, kor'6 n;lk.

CORONADO, Francisco Vasquez ( ? - c.15-1'.)). A Spanish explorer. He came to the New World about 1535, and, by marrying Doiia Beatriz, the daughter of Estrada, the royal treas- urer for New Spain, secured preferment at the viceregal Court in Mexico, He was appointed Governor of the Province of New Galicia. and in 1539 secured the conunand of an expedition for the conquest of the "Seven Cities of Cibola,' which the friar Marco de Niza claimed to have discovered on a preliminarv expedition earlier in 1539. On February 23, 1540, Coronado started from Compostela with a large force of horsemen, infantry, and native allies, supplied with artil- lei-y and abundant munitions and food. He fol- lowed the western coast of ilexico till some distance beyond Guaymas, and then crossed the mountains into southeastern Arizona. On July 7 he reached and stormed the chief city of Cibola, the stone pueblo of Hawikuh. now repre- sented by large ruins a short distance west of the pueblo of Zuni, in New Mexico. Making this his headquarters, Coronado sent expeditions to the West, which explored the countr.y as far as the Moqui villages of Tusayan, and to the Grand Canon of the Colorado, which was first seen by Europeans when the soldiers under Lopez de Cardenas reached it early in September. 1540. Other parties explored toward the east, and in September Coronado moved his forces to the Rio Grande, camping in the village of Tiguex, near Bernalillo, Xew ^Mexico. During the win- ter the natives of the river villages were sub- jugated after a fierce resistance. In April, 1541, Coronado led his whole army across the moun- tains into the great buft'alo plains of Arkansas and Indian Territory. Finding that he was being misled by a native guide, he sent his foot soldiers back to the Rio Grande, while he. with thirty
