Sixteen years have now passed since Mr. Davidson's Monograph of the British Secondary Brachiopoda appeared, and as numerous additions have been made from time to time, it is my present object to collate the scattered records of the additional species, and to supplement such information by notices of new or little known forms.
page 551 note 1 Waldheimia Mariæ, d'Orb, regarded by Mr. Davidson as a variety of W. cortmta, is described as a distinct species by E. Deslongchamps Pal. Fr. t. 20, f. 1–7; it occurs in the Marlstone of Ilminster.
page 552 note 1 According to E. Deslongchamps, three varieties of S. rostrata, described by Mr. Davidson, are distinct species, and are respectively named S. Hartmatmi, Ziet, S. pinguis, Ziet, and S. ascendem, E. Deslong; they occur in the Marlstone of Somersetshire.
page 553 note 1 Mr. Moore records R. subtetrahedra, Davids., in the Marlstone of Ilminster; R. subvariabilis, in the Middle Lias, Holwell; and R. concinna, in the Middle Lias, Camerton. I regard these as doubtful determinations.
