AUeyne Nicholson, PalaeozoicCorals, Monticulipora, 1881, chap. ii.). Finding these terms incon-venient for purposes of description, we propose to substitute for them thefollowing :—Autopores (= large corallites ), Mesopores ( = interstitialtubes ), and Acanthopores ( = spiniform corallites). The term corallites will be used only in a general sense when refer-ring to the tubes of which the colonj^ is made up. Fiff. 1. Fig.
