SILURIAN CORALS. 



685 



Formation and locality in England. Wenlock Limestone, Gleedon Hill, Wenlock. The 

 specimen figured is in the collection of Mr. Bowerbank, and was found at Wenlock. 



Foreign localities and authorities. Government of Moscow, Fischer ; Olne (Belgium), Gold- 

 fuss, Milne Edwards ; Gothland, Hisinger ; Sweden f Schlotheim. 



Of these foreign localities, Olne is considered by Von Dechen (German trans. De la Beche's 

 Man.) to be carboniferous limestone ; but Goldfuss states that it is transition, and he con- 

 stantly distinguishes between Bergkalk and Uebergangskalk. Hisinger, Bronn, and Fischer 

 mention S. reticulata as found at localities where other Silurian (transition) fossils occur. Du- 

 mont also enumerates S. ramulosa, stated by Goldfuss to be found at Olne, among his lists of 

 transition or Silurian fossils. 

 Syringopora bifurcata, sp. n. Lons. PI. 15. f. 11, 11«, 11 b. — 11 upper surface and vertical section, 

 11 a under surface, 11 b tube magnified. 



S. Branched, bifurcated, distance between bifurcations short ; the branches also anastomose, 

 or are united by intermediate transverse tubes. Surface of branches smooth or wrinkled ; 

 longitudinal striae sometimes visible around the upper part of the tubes ; opening of the tubes 

 nearly round ; internal structure very irregular. 



The growth of this coral, probably from the action of temporary currents, is singular. The 

 matrix of the specimen is a hard grey limestone, and the slab was about six inches square and 

 an inch and a half thick in the deepest part, gradually thinning off towards the edge. The 

 whole of the under surface was covered with horizontal, ramifying tubes, represented in PI. 15. 

 f. 11 a ; but the branches, where space had permitted free growth, regularly bifurcated. 

 The upper surface exhibited tubular openings more or less connected, and this part of the 

 specimen resembled an Aulopora. On breaking the slab, vertical, anastomosed or united tubes 

 were exposed (f. 11.) ramifying from the lower to the upper surface; and a connexion could, 

 in some places, be traced between the horizontal branch and the opening on the top of the 

 specimen.
