richly clad, as is the well-known Baltimore oriole, golden robin or hangnest of the United States, _Icterus baltimore_, whose brightly contrasted black and orange have conferred upon it the name it most commonly bears in North America, those colours being, says Catesby (_Birds of Carolina_, i. 48), the tinctures of the armorial bearings of the Calverts, Lords Baltimore, the original grantees of Maryland, but probably more correctly those of their liveries. The most divergent form of _Icteridae_ seems to be that known in the United States as the meadow-lark, _Sturnella magna_ or _S. ludoviciana_, a bird which in aspect and habits has considerable resemblance to the larks of the Old World, _Alaudidae_, to which, however, it has no near affinity, while _Dolichonyx oryzivorus_, the bobolink or rice-bird, with its very bunting-like bill, is not much less aberrant. (A. N.) FOOTNOTE: [1] The number of names by which this species was known in ancient times--_Chloris_ or _Chlorion_, _Galbula_ (akin to _Galgulus_), _Parra_ and _Vireo_--may be explained by its being a common and conspicuous bird, as well as one which varied in plumage according to age and sex (see ORIOLE). Owing to its general colour, _Chloris_ was in time transferred to the Greenfinch (q.v.), while the names _Galbula_, _Parra_ and _Vireo_ have since been utilized by ornithologists (see JACAMAR and JACANA). ICTINUS, the architect of the Parthenon at Athens, of the Hall of the Mysteries at Eleusis, and of the temple of Apollo at Bassae, near Phigalia. He was thus active about 450-430 B.C. We know little else about him; but the remains of his two great temples testify to his wonderful mastery of the principles of Greek architecture. IDA (d. 559), king of Bernicia, became king in 547, soon after the foundation of the kingdom of Bernicia by the Angles. He built the fortress of Bebbanburh, the modern Bamborough, and after his death his kingdom, which did not extend south of the Tees, passed in turn to six of his sons. The surname of "Flame-Bearer," sometimes applied to him, refers, however, not to Ida, but to his son Theodric (d. 587). See J. R. Green, _Making of England_, vol. i. (London, 1897). IDAHO, a western state of the United States of America, situated between 42° and 49° N. lat. and 111° and 117° W. long. It is bounded N. by British Columbia and Montana, E. by Montana and Wyoming, S. by Utah and Nevada, and W. by Oregon and Washington. Its total area is 83,888 sq. m., of which 83,354 sq. m. are land surface, and of this 41,851.55 sq. m. were in July 1908 unappropriated and unreserved public lands of the United States, and 31,775.7 sq. m. were forest reserves, of which 15,153.5 sq. m. were reserved between the 1st of July 1906 and the 1st of July 1907.
