1897.1 Report of the Geological Branch. 25 



This record from Dundas is, as far as we know, the most 

 westerly one made of the occurrence of marine shells from raised 

 beaches along the valley of the St. Lawrence between Montreal 

 and Kingston ; but bones of the Beluga V ermontana (a white 

 whale) have been recorded from near Cornwall and in the Riviere 

 Beaudette gravel beds. 



(19) At the last locality mentioned, the late N. J. Giroux 

 obtained the following species of marine organisms : 



1. Macoma fragilis, Fabricius. 5. Balanus crenatus, Burguiere. 



2. Macoma calcarea, Cheijinitz. 6. Balanus Hameri, very large and tine

(20) Fossil Insects. — Green's Creek and Besserer's Grove, 

 Ottawa River, in calcareous nodules : 



1. Tenebrio calculensis, Scudder. 3. P'onax ledensis, Scudder. 



2. Byrrhus Ottawaensis, Scudder. 4. Phryganea ejecta, Scudder. 



Of these. No. 3 was collected at Green's Creek by Sir Wm. 

 Dawson, and Nos. i, 2, and 4 were obtained in nodules from the 

 same locality by the writer. 



Further researches will no doubt reveal an interesting insect 

 fauna. So far, all our fossil insects from Green's Creek are forms 

 which are not known as existing species to-day. 



The foregoing species were found in the marine beds of the 

 Ottawa or St. Lawrence valleys ; but amongst the newer over- 

 lying deposits- of fresh water and estuarine origin, — marl 

 deposits form a conspicuous and interesting group, and hold 

 fossil shells, &c. 



Among the interesting species recorded from shell-marl 

 deposits in the Ottawa Valley are the following : 



(21) Lake Clear, near Eganville,* Ontario. 



1. Physa heterostropha. 5. Cyclas orbicularis. 



2. Planorbis campanulatus. 6. Unio complanatus. 



3. Planorbis bicarinatus. 7. Anodon fluviatilis. 



4. Paludina decisa.
