negretti

noun

1. A sheep of a Merino strain of Spanish origin, known for having very fine wool.

   “If a man with large means intends to raise for wool merely, or principally, I leave it open to him to select Negrettes or Combwools, as both will pay with necessary care; and although I belong to the old merino school, I am last to deny the qualities of a Cotswold.”
