PRELIMINARY NoTE oN NEw SPECIES OF SPONGES 
FROM THE QUEBEC GROUP aT LiTtLE Métis. 
By Sir J. Wit1u1am Dawson, LL.D., F.R.S. 
Little Métis Bay presents a good section of rocks of the 
Quebec Group, including sandstones, slates and conglomer- 
ates similar to those which characterise this series of beds 
along the south shore of the St. Lawrence. These beds 
have afforded a species of Retiolites, allied to or identical 
with &. ensiformis of Hall’, worm-burrows of various forms, 
including a spiral form similar to Arenicolites spiradis, and 
radiating markings of the kind elsewhere known as Astro- 
polithon. A small species of Obolella also occurs, resembling 
V. 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 stratigraphival position 
' Identified by Prof. Lapworth.
