The only traces of the connecting processes consist in occasional Hpiniform or tubercu- lar projections of the epitheca, which do not, however, reach contij^uous corallites. Accordinp^ to Mr. lUUings, the distance between the coriillitcs varies from three to eiiiht lines ; but in all tlie specimens I have seen, the distance is less than this. In fact, owing to the flexuous course taken by the corallites, and more especially to their being by no means strictly par- allel, their distance apart is very variable; and they are very often in contact for considerable distances. In the absence of septa and in possessing infundibuliforra tabuloc, the present form agrees with the normal examples of Si/riivjopora. LocalUji and Forinalion.—Rare in the Corniferous Limestone of Lot G, Con. 1. Wainflect. Also at Woodstock (Billings). Gemis AuLOPORA (Goldfuss). Corallum creeping, increasing by parietal gemmation ; the corallites pyriform, trumpet- shaped, or cylindrical, the cavity of each communicating with that of the one from which it springs. No tabuloB ; septa absent, or represented in a rudimentary form by longitudinal striae, or rows of minute spines. The corals of the genus Anlopora have often the closest resemblance to young colonies of Sijringiypura, before the latter have commenced to throw up corallites vertically. There is thus reason to think that some of the described species of Anlnpora may be truly of the nature of im- mature examples of Si/riii/jupom, though others appear to be undoubtedly mature and distinct. Mr. Billings has described three species of this genus, all peculiar to Canada, from the Corniferous Limestone of Western Ontario, and all of these have come under my notice. I have also to record specimens which appear to be in every respect undistinguishable from A, tuhceformU (Goldfuss). 43. AuLOPOKA FiLiFOiiMis (Billings). Aulopom fiUformis
