Another very important memoir upon the " Tabulate Corals " 

 was published in 1873 ^Y Dr Gustav Lindstrom (Nagra an- 

 teckningar om Anthozoa Tabulata, Ofversigt af. Kongl. 

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

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

 the distinguished Scandinavian palaeontologist entirely aban- 

 dons the "Tabulata" of Edwards and Haime as a distinct 

 division of the Corals ; Labechia, E. and H., is placed amorig 

 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 Poritidtz, among the 

 Perforate Corals ; the Heliolitida are considered as forming a 



1 In a note, Dr Duncan adds that though not satisfied (1872) that Millepora is a 

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

 to the extremely close relation between Heliolites and Heliopora, since so entirely 

 confirmed by Mr Moseley.
