The presentation to our Provincial Museum by Henry Lawson, Esq., of three interesting boulders from our tisliing banks, specially directed attention to tlis .subject of our paper. Each of the.se i^ adorneil by a prominent and singular organ- ism, which attracted the attention of the fisliertnan who found them. To the striking and puzzling character of these we are indebted for the preservation of the boulders and their attacht-s. The bouldeis are of Lower Cambrian (juart/ites. They were brought up from a deptii of <).'> fathoms. Our Museum has a number of other bouKlers from the same l)anks. Some of these we have hid foi- many 3'ears. Other interesting ones have been received from Mr. Lawson and others, since we began our investi- gations. During my glacial researches I have directed the Devil's Island fishermen to brinjj l)oulders from the shore of that Island and the fi ihing banks, with or without attaclu's, I am thereby enabled to ascertain that our glacial transportation had extended a considerable distance into the Atlantic. I have already noted Thrum Cap and its shoal as the aUhtm thale of this glacial transportation. We are not disposed, on the evidence of our boulders, to extend it to 60 or NO fathoms, or 2(1 miles beyond Thrum Cap or Devil's Island. This diuji have been effected by Itergs or floes from our glaciers, ice sheets, or other causes. It is possible that icebergs from Aictic regions, which are often seen on our coast, borne along by the Arctic cuirent, may have contributed their quota to the boulders of our fishing banks. This, however, is only a peradventure. Our Boulders are — 1. Arch.ean CJranite, of Halifax. "r ■ " r 200 CJLACIAI, IIOULDKIIS OF oril FISHKHl KS.— IIONKVMAV. 2, 3, 4, 5, (].

When I directed particular attention to it, I found that it was a limestone. The application of the hammer showed that the perforations were deeper and larger than they appeared, and were occupied by Saxicava and Ophltira. The limestone is also recognized as of Lower Caiboniferous age. (N.) is another limestone boulder. It is regularly stratified. •Saxicava have penetrated the stiata horizontally ; the upper strata present the aspect of a coral. This is caused by a coating of nullipores and bryozoa, which appears chalky from exposure to the rain and sun. It thus assumes quite a cretaceous aspect. The hammer shows the true character of the limestont'. An Ophitira and a small h'c/iinus occupied cavities. (O.) is of the same character with chalky patches. (P.) is another limestone boulder. This has been perforated by Saxicava entering on the edges of the lamina'. The perfora- tions are empty. (Q.) Is a thoroughly perforated boulder (.f Lower Carboniferous Limestone. Its cavities contain one or two saxicava and serpulw. A flat side is thickly studded with Spirorbts of, at least, two species. Numerous Serpulini lie among these. (R.) Is another limestone boulder, much perforated by Saxicava. A small one lies in a cavity. (S ) Is another.

Wo have also two larj^e, detached, bushy spon^'es with thick and Hhort stalks. These are licnl<'v unitiue. It seems to have been unattached. This completes our series of sponges. Their aspect also is decidedly Boreal, as well as that of the othei' invertebrata of our Fishing Banks. I have yet to ncite the presence of J{((i>fnilix). We would Hflfl a few notes to the Paper reatl which will hrin;^ ■'■nder notice otlicr invcrtehrates not attached wholly to houlders. Wo are indebted to others for those already noticed. The fiucceedinii have been collected in our walks aiouml the shores of Point Pleasant. It is many years since we first noticed sponj^es with other attacli's on the "so-called roots," of the great quantities of Laniinaria and other lar^j^e alj,'ii' cast ashore by the sea after stoiins which had torn them from tlio rocks to which they had been attaclied. Iferetofore, we re<.(arded these as of no peculiar interest, ('lioice specimens of the sponi^'es were, however then collected, put in proper jars witli alcohol, and placed in the lowest position in ourAlcoholicCollection. These spon^'os are associated with, and sometimes almost envelopinjects of interest, a densely reticulated alga with the spawn of small fish newly developed. Putting it into a small bottle having alcohol, I observed a number of small, oval sponges. One of these 1 have just examined, and found it to be a Mijxilla. I have given it the specific name pisclniae. I would, in conclusion, notice the valve of a modiola.
