Preliminary Note* on New Species of Sponges 

 FROM THE Quebec G-roup at Little Metis. 



By Sir J. William Daavson, LL.D., F.R,S. 



Little M^tis Bay presents a good section of rocks of the 

 Quebec Group, including sandstones, slates and conglomer- 

 ates similar to those which chaiacterise this series of beds 

 along the south shore of the St. Lawrence. These beds 

 have afforded a species of Betiolites, allied to or identical 

 with JR. ensiformis of Hall\ worm-burrows of various forms, 

 including a spiral form similar to ArenicoUtes spiralis, and 

 radiating markings of the kind elsewhere known as Astro- 

 polithon. A small species of Obolella also occurs, resembling 

 0. Ida of Billings. In the conglomerates are limestone 

 boulders, holding fragments of Trilobites of the genus 

 Solenopleura and other fossils; but these seem to be of Mid- 

 die Cambrian age, or considerably older than the beds in 

 which they occur. 



There can be no doubt, from the stratigraphioal position
