Another very important memoir upon the " Tabulate Corals " 

 was published in 1873 by Dr Gustav Lindstrom (Nagra an- 

 teckningar om Anthozoa Tabulata, Ofversigt af. Kongl. 

 Vetensk. Akad. Forhandl., 1873. Translated in the Ann. and 

 Mag. Nat. Hist, sen 4, vol. xviii. p. i, 1876). In this paper 

 the distinguished Scandinavian palseontologist entirely aban- 

 dons the ''Tabttlata'' of Edwards and Haime as a distinct 

 division of the Corals ; Labeckia, E. and H., is placed among 

 the Hydrozoa, near to Hydractinia ; Monticulipora, D'Orb., 

 Fistulipora, M'Coy, and some other forms, are regarded as 

 Polyzoa ; the Favositidce are placed in the Poritidcu, among the 

 Perforate Corals ; the Heliolitidce are considered as forming a 



Mn a note, Dr Duncan adds that though not satisfied (1872) that Rlillepora is a 

 Hydrozoon, he has great doubt about its Madreporarian affinities. He also points 

 to the extremely close relation betv/een Heliolites and Heliopora, since so entirely 

 confirmed by Mr Moseley.
