 are printed as plates. Ottawa, October 23 [i.e. November 21], 1913. 



ri^HE papers in this new publication are distributed under the 

 ±_ headings Palaeontology, Palaeobotany (thus showing that by 

 Palaeontology is meant Palseozoology), Mineralogy, Natural History 

 (which appears intended to include both recent Botany and recent 

 Zoology), and Anthropology (which from the title of the only paper 

 under this heading appears to include Archaeology). The Geological 

 Survey of Canada is thus continuing the traditions of the time when 

 it was known as the Geological and Natural History Survey of 

 Canada. There is no heading Geology, for it is doubtless intended 

 that papers dealing with that subject will continue to be published 

 as heretofore in the direct Reports of the Survey. The majority of 

 the papers in the present number have, however, a geological bearing. 



The first paper is a redescription of the type-specimen of Ottawa- 

 crinus typus, W. R. Billings, by Dr. F. A. Bather, who considers that 

 all the radials of this form are transversely bisected, and finds it 

 difficult to draw any clear distinction between the upper halves of 

 such radicles and the proximal brachials. In the following "Note 

 on Merocrinus " Dr. Bather applies this view to that genus also. 

 Mr. L. M. Lamhe records the occurrence of Helodont teeth in beds 

 helieved to he of Upper Devonian age in Alberta. Dr. P. E. Raymond 

 publishes "Notes on Cyclocystoides^'' , in which he suggests that this 

 curious fossil may be the highly specialized root of a free crinoid, 

 " a sort of sucker-disk." " It is even possible," he says, "to think 

 of this disk as a swimming organ." Dr. Raymond also has two 

 papers on Trilobites, in one of which he describes a new species of 

 Solasaphiis and in the other some new species of Asaphidae. Tlie 

 same author describes two new species of Tetradium, one of which is 

 from the Lowville Beds of Ontario, but the locality and horizon of 

 the other are not stated — a probably quite unintentional omission. 

 Returning to the Trilobites, Dr. Raymond revises the species that 

 have been referred to the genus Bathyurus and erects for some of 

 them the new genera Petiguriis [sic'], Systrmir-us, Haplocomis, 

 Platycolpus, Plethopeltis, Gonmrus, and Leiostegium. Miss A. E. 

 Wilson then founds a new genus of Brachiopod, Oxoplecia, for a 

 species 0. calhoimi, from the base of the Utica. 



The two papers under Palaeobotany are by Mr. "W. J. Wilson, who 

 describes Lehephyllum, a new genus of Dicotyledonous plant from the 

 Tertiary beds of Kettle River, B.C. This is based on leaves of 

 uncertain affinity, but the name in any case should have been 

 LebetopTiyllum. He also describes a new species of Lepidostrohus 

 from the Minto Coal-mines. 



Under Mineralogy Mr, R. A. A. Johnston discusses an occurrence 

 of Prehnite at Adams Sound, Admiraltj' Inlet, Baffin Island. 



If this Bulletin is intended for the prompt publication of short 

 papers it may prove very useful, but we observe that the MS. of the 

 first two papers was transmitted in July, 1910, so, at any rate, that 

 is not an example of promptitude.
