R. Etheridge, Jim. — Glacial Deposits of Lewis. 553 



Traigh Chrois and Traigh Shuain oboist. They are both sitiiated on 

 the north-west coast of Lewis, a little to the south-west of the Butt. 

 The former is nearly 1 J miles west of the village of Swainabost, and 

 the latter about 1 mile north-west of the same. We likewise ob- 

 served a similar set of fossiliferous beds on the coast to the south-east 

 of Port of Ness, but time did not permit us to make any collection. 



In the succeeding list I have indicated the two localities by the 

 initials T.C. and T.S. respectively, the former for Traigh Chrois, 

 the latter for Traigh Shuainoboist. Those species which have been 

 met with in the Boulder-clay of Caithness are indicated by an asterisk 

 placed before them.

The foregoing list will show that the largest proportion of our 

 fossils were obtained from the intercalated laminated beds, although 

 we found both the Upper and Lower stony clay to be fossiliferous.
