AuLOPORA, Goldfuss, 1830. 



MiLLEPORA (dichotoma), Liiinceus. 

 TuBiPOEiTES (serpens), Scklotheim. 

 Catenipora (axillaris), Lamouroux. 



Diagnosis. — " Stirps calcareaj e tubulis obconicis, vacuis e latere proliferis, singulis 

 ostiolis terminalibus exsertis."^ (Goldfuss.) 



Copying Milne Edwards, Aulopora may be described thus : " Tubes calcareous, 

 with a round opening more or less projecting or elevated, originating laterally from 

 each other, and forming by their union a creeping reticulated Coral, or a raised 

 tubular mass.'" 



This genus, which Goldfuss established on the Catenipora axillaris of Lamouroux, 

 consists of ramose, creeping, unilocular tubes ; and has in its young stages, before it 

 has become complicated in its ramifications, much of the aspect of Aledo, and some 

 other repent, dendritic, tubular Bryozoic Corals. The latter, however, differ from the 

 present genus in ha^dng chambered or celluliferous tubes, a difference that seems to 

 warrant the placing of Aulopora among the Alcyonarias. 



In my ' Catalogue' Bronn's genus Stomatopora is considered as synonymous with 

 Aulopora, on the authority of what is stated in the ' Lethsea Geognostica,' p. 54 ; but 

 I now suspect that it is only Aledo which stands in this position. I am not aware 

 that any Auloporas have been found higher in the series of formations than the 

 palaeozoic.

Stomatopora (Aulopora) dichotoma, Lamouroux. King, Catalogue, p. 6, 1848. 



Diagnosis. — Stems and branches slender, beaded, composed of a single series of 

 flask-shaped cellules, which are narrow at their proximal end, and swelled at their 

 distal extremity. .Branches originating on the sides of the cellules near their distal 

 extremity. Cellule-apertures ...(?) 



Aulopora Voigtiana agrees in appearance so closely with Lamouroux's Alecto dichotoma, 

 that I was formerly led to believe in their identity ; the stems and branches in the 

 latter species, however, are too uniform in width to admit of the identification. 

 Specimens occasionally occur decidedly more branched than the one which is 

 figured. 



I have not yet been able to ascertain whether this species is unilocular or chambered ;
