AuvLopora, Goldfuss, 1830. 
MiLippora (picHotoma), Linneus. 
TUBIPORITES (SERPENS), Schlotheim. 
CATENIPORA (AXILLARIS), Lamouroux. 
Diagnosis.—“ Stirps calcarea, e tubulis obconicis, vacuis e latere proliferis, singulis 
ostiolis terminalibus exsertis.”’ (Goldfuss.) 
Copying Milne Edwards, Awopora 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 Alecfo, and some 
other repent, dendritic, tubular Bryozoic Corals. The latter, however, differ from the 
present genus in having chambered or celluliferous tubes, a difference that seems to 
warrant the placing of 4ulopora 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 ‘ Lethzea Geognostica,’ p. 54; but 
I now suspect that it is only A/ecto which stands in this position. I am not aware 
that any Auloporas have been found higher in the series of formations than the 
palzeozoic.

StomaTopora (AULOPORA) DIcHoTOMA, Lamourouw. King, Catalogue, p. 6, 1848. 
Diagnosis.—Stems and branches slender, beaded, composed of a single series of 
flask-shaped ce//ules, 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 ;
