ZONE OF AMALTHEUS SPINATUS. 



107 



On the south side of Portree Harbour, Isle of Skye, Professor Tate found the Spinatus- 

 beds to consist of a hard, calcareous, yellowish-grey, thick-bedded sandstone, about 

 40 feet in thickness ; the uppermost 5 feet of the Rock-bed is more bluish and calcareous, 

 and appears to form the basement-bed of the Upper Lias ; from these strata he collected 

 the following Molluscan fauna.
