258 The Ottawa Naturalist. [February 



and obtained there on the huge blocks of sandstone and shale a 

 series of interesting tracks and trails of marine organisms, together 

 with one or two rare fossils preserved as casts of the interior of 

 the animal. 



Hull, Que. About the end of May, whilst there were a few 

 members of the Royal Society of Canada still in our city, some of 

 the members of the geological section, acting as guides, visited the 

 ** Heap " in Hull, as well as the excavations for the main drain, 

 in Ottawa, where the Utica formation was well exposed. The 

 species collected were subsequently determined and will serve to 

 Illustrate the geology of our district in remote portions of the 

 Dominion. 



Besserers, Otit. The exceedingly low state of the water in the 

 rivers and streams about Ottawa afforded an unusually fine oppor- 

 tunity to collect nodules from the fossiliferous clays of the Green's 

 Creek period or formation (as Prof. Penhallow styles it) and 

 though considerably incapacitated from doing much work during 

 the autumn owing to an accident which had befallen the »vriter, a 

 number of collections were made. 



Rideau Sand Quarry. About two miles up the Rideau River 

 above Hog's Back, along with Mr. W. J. Wilson, also a leader 

 of the Club and a foremost student in Pleistocene geology in our 

 midst, we visited this interesting locality and obtained four species 

 of drift fossils preserved in a matrix of coarse sand. These 

 comprise the well known Saxicava riigosa, Linnasus, Macoma 

 Balthica, Linneeus, Mytikis editlis, Linnaeus, and a species of 

 Belanus which is difficult to identify with any of the forms now 

 living in. the waters of the Lower St, Lawrence or shores of 

 the Western Atlantic. Its characters ally the form more closely 

 to Balanus porcatus de Costa than to any other. I am indebted 

 to Dr. Whiteaves, who was shown the specimens in question, 

 and he thinks that this as well as most of the species of Balanus 

 from Canada need revision and careful study. 



Below the residence of Mr. T. C, Keefer, RockclifT, along the 

 shore of the Ottawa river, an excellent section of the Chazy form- 

 ation may be seen especially in its most arenaceous development.
