FILDES, Metz, SIR (Samuel) Luke, Eng lish portrait and genre painter: b. Liverpool 1844. His first Academy picture was 'Night fall) (1868), and among other pictures since then he has exhibited 'The Loosened Team' (1869) ; 'Fair, Quiet, and Sweet Rest' (1872) ; 'Simpletons) (1873) ; 'Applicants for Admis sion to a Casual Ward) (1874) ; 'Betty' (1875); 'The Widower) (1876) i 'Playmates' (1877) ; The Return of the Penitent' (1879) ; 'The Village ; 'Venetian Life' 'The Al-fresco Toilette' ; 'The Doctor' (1892), and state portraits of King Edward and Queen Alexandra. Several of these, par ticularly his famed 'Casual show powers of realism in painting not unlike those of Dickens in fiction — for whom he illustrated 'Edwin Droo&— but his later works are more striking from their color-effects. He was knighted in 1906.
the fishes of the plectog nath family Monacanthida., so-called from their skins being roughened by minute rough scales.
The species are numerous, small, plain in color herbivorous, lean and not good for food; and are mainly found in the tropical seas. The best known American species is Alutera schcepfii, which ranges as far north as Cape Cod, and often shows a decided orange tint upon its olive-gray sides. It reaches a length of 24 inches, as also does its relative the unicorn fish (A. scripta) of the West Indies. A differ ent and much smaller file-fish is the widely dis tributed *leather-fish" or "fool-fish)) (Monacan thus hispidus). The Spanish-American fisher men give the name alija° to all these fishes. These fishes were formerly classified with the trigger-fishes (q.v.) in the family Balistida, from which they differ conspicuously in having but one erectile dorsal spine.
