    A cap worn by serjeants at law.

  • Black's Law Dictionary: 2nd Edition

    A title given to serjeants at law, who are called "serjeants of the coif," from the coif they wear on their heads. The use of this colf at first was to cover the clerical tonsure, many of the practising serjeants being clergyman who had abandoned their profession. It was a thin linen cover, gathered together in the form of a skull or helmet; the materini being afterwards changed into white silk, and the form eventually into the black patch at the top of the fofensic wig, which is now the distinguishing mark of the degree of serjeant at law.
