lites of the former genus; in all other respects, the resemblance 

 between the two genera is very close. 



The absence of connecting processes, the mural pores, and the 

 open character of the central tube, sufficiently distinguish Syringo- 

 lites from Syringopora. 



Syringolites Huronensis, sp. nov. 



Besides the above-mentioned generic characters, it may be added 

 that the upper surface of the corallum is nearly flat ; the walls of 

 the corallites are well defined, and occasionally possess a wavy 

 outline. The calice formed by the uppermost tabula is moderately 

 deep, and gradually slopes from the sides to the central tube. The 

 corallites are of generally uniform size, about one line in diameter, 

 tbe central tube is about |- line wide, and the tabula? are about -J line 

 apart. There are on the upper surfaces of the tabula? about twelve 

 complete rows of septal tubercles or spines extending from the sides 

 of the corallites to the central tube, and between these are incom- 

 plete rows, which only reach part of the distance. The central tube 

 is of nearly uniform diameter throughout. The mural pores occur 

 at irregular intervals, and appear to alternate with each other. 



The specimens are all silicified and free from the dolomitic matrix, 

 so that their characters are very distinctly shown. Not infrequently 

 the central tube has been filled up with silica, and in this condition 

 it presents the appearance of a solid columella, for which it might be 

 mistaken. 



Formation and Locality. — Not uncommon in the Niagara dolomite 

 (Wenlock), near Manitouwaning, Great Manitoulin Island, Lake 

 Huron. 



III. — On some Recently Discovered Teeth of Ovibos moschatus, 



from Crayeord, Kent. 



By William Davies, F.G.S., 

 of the British Museum. 



THE great geological interest which attaches to the fossil remains 

 of the Musk-ox or Sheep (Ovibos moschatus, Blainv.), found in 

 British Pleistocene deposits, and the few instances hitherto recorded 

 of their occurrence (together with a recent discovery brought to my 

 notice), have suggested to me the desirability of a brief enumeration 

 of them. 



They consist respectively of a portion of a skull, from the 

 low-level Thames gravel, near Maidenhead, first described by 

 Prof. Owen ; 1 a fragment of a skull from the gravels of Green 

 Street Green, near Bromley, Kent ; both of which are preserved 

 in the British Museum ; " fragments of the skulls of a male and 

 female, from the gravels of the Avon at Freshford, near Bath ; " 

 a " basal portion of a skull obtained from the gravel of Barnwood, 

 near Gloucester ; " and, " a nasal bone, a tibia, and an astragalus, 

 from the low-level gravels of Fisherton," near Salisbury ; and, 

 lastly, " the head of a fine bull, wanting the facial bones, dis- 

 covered and exhumed by Prof. Boyd Dawkins, from the lower
