drawn from the fresh appearance of the post-glacial beaches 

 from the height of driftwood, from the silting of the mouths of 

 rivers that flow swiftly through alluvial plains or from the tales 

 of the Indians who would doubtless regard the formation of a 

 sand-bar as the receding of the the waters, is delusive, and that 

 the post-glacial uplift of this portion of the shore of the Hudson 

 Bay has virtually ceased, and that the land has now reached a 

 stable or almost a stable condition." 



In a previous issue of this magazine, (March No.), Dr. Bell 

 holds the view that the shores of Hudson Bay are rising. His

LamBE, L. M. — Description of a supposed new genus of Polysoa 

 from the Trenton Limestone at Ottawa!' Ex. Can. Rec. 

 Science, Jan. and April, 1896. 



In this short paper Mr. Lambe describes a fossil from the 

 Trenton Limestone of Hull, P.Q., suggesting for it a new genus 

 Astro pontes, and giving it the specific name A. Ottawaensis. It 

 is stated to " approach most closely to the Fenestel/idcz" but at 

 the same time to differ considerably from any other known 

 Polyzoa. A plate with three figures beautifully drawn by Mr. 

 Lambe himself illustrates the paper, and shows some of the 

 principal characters of this interesting new form. — J. B. T.
