Stinipson further says : — 



" It is interesting to notice a great similarity of the 

 Fauna of this region and that of Greenland, as described 

 by 0. Fabricius and others. The correspondence is very 

 great, especially among the Tunicata and Echinodermata, 

 of which the species are nearly the same." 



Another interesting point of comparison is that between 

 the existing Acadian Fauna and that of the Canadian 

 Pleistocene period. Many of the Invertebrata (particu- 

 larly the Mollusca) are common to both, and the Capelin 

 {Mallotus Villosus) described by Cox as " never ranging 

 further south than the shores of New Brunswick " occurs, 

 as is well known, in the clay concretions of the Pleistocene 

 at Green's Creek, near Ottawa. 



While it is not my intention to enumerate a list of the 

 species collected in this vicinity, a brief reference to some 

 of the commoner and more important forms may be of 

 interest. 



Of Coelenterata may be mentioned various Hydroids, of 

 which Phimularia and Sertidaria are the most common. 

 The large " Jelly-fish " (Aurelia Flavidida) is abundant, 

 and another closely related form (Ptychogena Lactea) — 

 conspicuous by the prominent white cross on its disc — is 

 occasionally found. The common Sea-anemone (Metridium 

 Marginatum) is frequently met with, but of Ctenophores, 

 such as Idyia and Pleurohrachia, so abundant at Halifax, I 

 saw but few. 



The class of animals popularly grouped together as 

 " Worms " is well represented. Conspicuous among these 

 are the large Carnivorous sea-worms of the genus Xereis^ 

 observed at low tide, partially extruded from their holes. 



On turning over the stones at low tide, almost every 

 one is seen to harbor various Nemerteans — those interest- 

 ing organisms with eversible proboscis and supposed Ver- 

 tebrate affinities, and a multitude of other interesting 

 forms may be obtained by digging in the mud and sand.
