A RED LETTER DAY IN THE HlSTORY OF PlCTOU AND GEOLOGY 

 OF DIVISION C. 



On the top of a hill at the end of the C strata mountaius, 

 on the line of the depression of the mountain summit already ob- 

 served, on the right of the McGillivray strata I found an ex- 

 posure of strata lithologically distinct fron D & C. These so 

 much resemble the B' strata of Doctor Brook, Arisaig Township,, 

 that I was led to search in them for fossils. This happened 

 on a day ever to be remembered in Pictou, when H. R. H. 

 the Prince of Wales was in Pictou en route to Prince Edward 

 Island. Few were in the country that day who could find the 

 ways and means of getting to the town, these not being available 

 I continued my search for fossils and found them. I collected 4 

 specimens belonging to a new species of Homalonotus which is 

 known in my collection as Homalonotus Siluriae Principis — 

 Prince of Wales Homalonotus, two large linguloe were discovered 

 also a discina and a form, Incertae sedis. 



DESCRIPTION. 



C and D strata as at Arisaig have each their characteristic homa- 

 lonotus. The number of specimens of a species of homalonotus 

 found in our new strata of the mountain seems to form a char- 

 acteristic. Homalonotus dawsoni is characteristic of D. Homalo- 

 notus salteri, M. S. is characteristic of C. 



This was considered by Salter from the appearance of the 

 pygidium to be Homalonotus delphinocephalus. When examined 

 by him the head of the form was unknown. Specimens of the 

 head were afterwards found which showed that it is not delphi- 

 nocephalus. I have regarded it as a new species and named it 

 after the late distinguished Palaeontologist of H. M. Geological 

 Survey of Great Britain. 



The thorax and pygidium are all that is known of the 

 Homalonotus Siluriae Principis. The thorax has the character of 

 the genus, being level backed; the pygidium is different from 

 that of Homalonotus salteri in not having a terminal spine. From
