certain number of specimens at the old well known localities 
of Top Sail Head, Brigus Head and Manuel's brook. Here is 
the list for the division m, or "Top Sail Head group, or hori- 
zon of Agraulos strenuus:^^ Oholella atlatitica, Kutorgina 
lahradot'ica, Scenella reticulata, Stejiothecarugosa andseveral 
varieties, Hyolitellus micans, Hyolites jnnnceps, Platyceras 
primctiviwi, a Gasteropod, Microdiscus speciosus and two 
other species, Olenellus Irmggeri new species, Avalonia 
Tnanuelensis n. gen., n. sp., Ptychoparia, Solenopleura Bom- 
hifrons and another species, Agraulos stretiuus and varieties. 
All those fossils belong to forms related to the fauna of the 
Scandinavian group of Scania, Lapland, Norway and Britain. 
I shall call attention to two points only ; the absence in New- 
foundland as well as in Europe of the genus Agnostus, and 
the presence of a Paradoxidean form called Paradoxides by 
Billings, Matthew and Howley, and Olenellus by Mr. Walcott. 
Until now Mr. Walcott has not published a description with 
figure of his Olenellus hroeggeri., so it is impossible to control 
in any way his reference of that new trilobite to the genus 
Olenellus {Elliptocephalus). But after the thorough researches 
of Dr. Holm, on the Olenellus IxjeruM, it is presumable that 
the Conception bay trilobite, like the Scandinavian species is 
not a true Oleriellus and belongs to Holmia. 
If Mr. Walcott had contented himself with his collection of 
fossils, which is certainly important and valuable, he would 
have rendered a true service to our knowledge of the primor- 
dial fauna of Newfoundland ; but unhappil}^ he had gone into 
an attempt to synchronize the strata of Newfoundland with 
those of Vermont, eastern New York, Massachusetts, Canada 
and the Rocky mountains, which is most confusing and at 
variance with facts. The fauna of the Scandinavian groups 
of Conception bay, is entirely different from the fauna of the 
Georgia group of Vermont, Canada, Western Newfoundland 
and Belle Isle strait. At Conception bay, all the forms found 
in Division m, Top Sail Head, Brigus and No. 2 of Manuel's 
Brook section, belong to older forms than the fossils of 
Georgia, Bic Harbor, etc. ; and without entering into details, I 
shall confine my remarks to the trilobites called Ole7iellus 
brceggeri^ and Olenellus thompsoni. All the trilobites of 
Scandianavia and Esthonia referred to Olenelhcs, do not belong 
to that genus, and as Mr. Walcott regards the Esthonian
