Reis' proposed the name Heterastraea for the genus here named 

 Antiguastrea; but, as R. F. Tomes had used Heterastraea for a genus 

 of Enghsh Liassic corals in 1888/'' Reis's name can not stand. Reis's 

 account of the cohimeUa in his description of Heterastraea is contra- 

 dictory. Regarding Heterastraea tenuilamellosa (Giimbel) Reis, he 

 says, ''zeigen ein verlangertes bhittartiges bis papilloses Saulchen." 

 The cokimella in that species, therefore, is lamellate. 



This genus of corals is important in its bearing on the correllation 

 of American and European Tertiary formations. At the end of his 

 table of the corals from the Reiter Schichten, Reis says:^ ''Aus 

 diesem Tabelle geht unzweifelhaft hervor, dass eretens die Reiter 

 Korallenlager und die rom Hallthurm mit denen von Haering 

 ganzlich stimmen, also keinen tieferem Horizont angehoren konnen 

 und dass zweitens dieser Horizont sowohl durch Haeringer Schichten 

 als auch durch die deutlichsten Beziehungen zu den unter- bis mittel 

 oligocanen Korallenlagern des Vicentins als solcher festgestellt ist." 

 Reis reports species of Heterastraea from Reit, Castelgomber-to. and 

 Crosara. 



There is in the United States National Museum (No. 155186) a 

 specimen of Heterastraea michelottina (CatuUo) Reis, received from 

 Prof. K. A. von Zittel. This specimen has a distinct, short, thick, 

 lamellar columella. It so closely resembles Antiguastrea ceUulosa 

 that specific distinction is difficult, perhaps even doubtful. Isastrea 

 elegans Reuss is referable to Antiguastrea. It is described after Anti- 

 guastrea ceUulosa (see p. 409, pi. 102, figs. 1, la). Astrea alveolaris 

 C^atullo ■* also belongs to Antiguastrea . Notes on it follow those on 

 A: elegans.
