6 & 7. Tue CouLtTeR 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 fluviatilis, and the larvae of Caddis flies, were 
observed under or attached to the stones in the stream; while in thie 
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 34 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 Hutomostraca. 
_ The following is the list of the Mollusca and Crustacea observed and 
identified with Sections VI. and VII :— 
MOLLUSCA. 
Py sidium pusillum (Gmelin). Moderately common in Section VI. 
and upper part of Section VIL.
