Thalassicollida
in zoölogy, a family of Radiolaria. The animals consist of structureless cysts containing cellular elements and protoplasm, surrounded by a layer of protoplasm giving off pseudopodia, which commonly stand out like rays, but sometimes run into another, and so form networks. The best known genera are Thalassicolla, Sphærozoüm, and Collosphæra. They are all marine, being found floating passively on the surface of most seas, and vary in size from an inch in diameter downward.

Thalassophryne
in ichthyology, a genus of Batrachide, with two species, from the Atlantic and Pacific coasts of Central America. The spinous dorsal is formed by two spines only, each of which is hollow, like the opercular spine, and conveys the contents of a poison bag situated at the base. The poison bags have no external muscular layer, and are situated immediately below the thick, loose skin which envelops the spines; the ejection of the poison can therefore only be effected by the pressure to which the poison bag is subjected the moment the spine enters another body.

Thalberg
SIGISMOND, a Swiss pianist; born in Geneva in 1812, where he received his early education under the supervision of his mother, the Bar oness Wetzlar. At the of 10 he removed to Vienna, where he continued his studies under the best masters, in preparation for a diplomatic career. Thalberg's first appearance as a pianist was at the age of 14, when he played at an evening party at Prince Metternich's. This success was followed up by numerous appearances in Paris , till, overcoming his father's scruples, he was allowed to abandon diplomacy for music. He made tours in 1839 through Belgium, Holland, England, and Russia, and afterward through Spain, Brazil, and North America, finally settling down at Naples in 1858. Thalberg married Madame Boucher, daughter of the celebrated Lablache. His musical compositions comprise more than 90 numbers, principally fantasies and variations. His operas "Cristina" and "Florinda" the latter played before the London in 1851-were absolute failures. As a pianist, in graceful and brilliant execution and in manual dexterity, he had scarcely a rival. He died in Naples April 27, 1871.

Thane
a title of honor or dignity among the Anglo-Saxons. In England a freeman not noble was raised to the dignity of a thane by acquiring a certain amount of land (five hides in the case of a lesser thane), by making three sea voyages, or by receiving holy orders. The thanes had the right of voting in the Witenagemot, not only of their own shires, but also of the whole kingdom, on important questions. There were two orders of thanes: The king's thanes, or those who attended at his court and held lands immediately from him, and ordinary thanes, or lords of the manor, and who had a particular jurisdiction within their limits. On the cessation of his actual personal service about the king, the thane received a grant of land. After the Norman conquest, thanes and barons were classed together, and the title fell into disuse in the reign of Henry II. In Scotland, thane signified originally a count or earl, one who ruled a county, or even in some cases a province. Afterward the title was applied to a class of non-military tenants of the crown, and continued in use till the end of the 15th century.
