. The Canadian record of science. Natural history. 228 Canadian Record of Science. Oldhamia. By G. F. Matthew, , Fig. 1. Fascicle of Oldhamia mag. f, Cambrian, Div. 1 b, Caton's Island, , Canada. About twelve years ago (1888) the writer collected from the Cambrian rocks of the St. John Group a fossil which he thought to be a fascicle of Oldhamia. The object was not described at the time, because he had hopes that in later explorations he might meet with better examples, or others that would throw a better light on the structural details of the fossil. This expectation was not realized, and therefore it seems desirable to put on record the description of this object, hoping that others may be able to supplement the information here given. Oldhamia is an interesting form, of which the first examples were found in the Wicklow Mountains in Ire- land, and were described by Edward Forbes. At first and for a number of years it was regarded as a characteristic fossil of the Lowest Cambrian, but later discoveries have given a wider range to the genus. Eobert Etheridge, Jr., says that Forbes regarded these iorms as probably belonging to the Polyzoa or Hydrozoa; but Mr. Busk, a high authority on the Polyzoa, did not recognize them as of that class, and suggested that they might be corallines after the type of Acetabulifera. Rev. Mr. Berkly also suggested this seaweed as a probable ally, because the structure, though jointed, showed no trace of definite cells such as Bryozoa (or Polyzoa) and Hydrozoa Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Natural History Society of Montreal.
