Century Dictionary and Cyclopedia
    • n aboma The name in Guiana of some very large boa or anaconda of the family Pythonidæ or Boidæ, of the warmer parts of America. The species is not determined, and the name is probably of general applicability to the huge tree-snakes of the American tropics. As a book-name, aboma is identified with the Epicrates cenchris, usually misspelled Epicratis cenchria, after the Penny Cyc. 1836. This is a species called by Sclater the thick-necked tree-boa. A Venezuelan species is known as the brown aboma, Epicrates maurus. Some such serpent is also called the ringed boa, Boa aboma. In any case, the aboma is a near relative of the anaconda, Eunectes murinus, and of the common boa, Boa constrictor. Compare boa and bom.
    • n aboma [capitalized] A genus of gobies found in Mexico and Japan, having more than 6 dorsal soines.
