GLAPISSANT, E, adj. squeaking, shrill.
    GLATTERON, V. Gratteron.
    GRATTER, v. a. to scratch, scrub or claw; to scrape or rake off; (le papier) to scrawl, write fast and ill; (une rentraiture) to smooth down with the nail; to pilfer, cabbage. 
    GRATTOIR, s. m. scratching knife, scraper. (Boyer's French Dictionary, 1848)

    5. Beste glatissant (Lös.); Bestia grattisante, grattigiante, gratisciante (R); Bestia Gratta santa (P); Gratisnti, Gratisante (S); Grata Sangre (V); Gaturas (TL).  Notice the remarkably close agreement between V and P.  V clearly goes back to an original where gl- had changed to gr- as it had done in the Italian.  The confusion arose from the Italian translator's failure to render the French participle.  It is instructive to note that in the Baladro, which apparently came directly from the French, the name is correctly rendered: Bestia Ladradora. (The Romanic Review, Todd, v.3, 1912).
