6 & 7. The Coulter Burn from Goldenhoof to the Bannock 

 and thence to the forth. 



The Coulter Burn after leaving Goldenhoof Dam runs eastward for 

 600 to 700 yards, then northward for a few hundred yards more, and joins 

 the Bannock not very far from the site of the famous battle of Bannock- 

 burn. Along the part of its course the water flows with considerable 

 rapidity except in a few places where quiet pools are formed. The fresh- 

 water limpet Ancylus jiuviatilis, and the larvae of Caddis flies, were 

 observed under or attached to the stones in the stream; while in the 

 quiet pools, as well as in the marshy places along its banks, a number of 

 Entomostraca and a few Mollusca were obtained. The Bannock Burn, from 

 where it is joined by the Coulter down to the village of Bannockburn, 

 also yielded a number of Mollusca and Entomostraca, but from that 

 village to the Forth, very few such organisms were observed, probably 

 owing to the water being more or less contaminated by the refuse from the 

 public works on its banks. Between the village of Bannockburn and the 

 Forth the Bannock flows between steep banks through a comparatively 

 level tract of country and its course is very tortuous. The distance as the 

 crow flies from where the Bannock is joined by the Coulter Burn to its 

 union with the Forth is scarcely 3 J miles, while the course of the burn 

 measures fully 6 miles. Though the water appeared to be contaminated, 

 both trout and sticklebacks were observed to be moderately frequent ; the 

 impurity of the water did not seem to have so much effect on these as on 

 the Entomostraca. 



The following is the list of the Mollusca and Crustacea observed and 

 identified with Sections VI. and VII : — 



MOLLUSCA. 



Plddium pudllum (Gmelin). Moderately common in Section VI. 

 and upper part of Section VII.
