Since the discovery of the above-named fossils by Captain Bedford, 
Mr. J. Thomson, of Glasgow, has visited the island of Pabba, where he 
found T. punctata, Sp. Walcotti, Bh. tetrahedra, and another species, 
which I was unable to determine. He also found in the Bay of 
Lussay, four miles from Bradford, in the island of !Skye, some ex- 
amples of Sp. Walcotti.

This is a common form in Scottish liassic deposits, although rarely found perfect. It was 
found by Captain Bedford in the Bay of Caisaig, Mull. Mr. J. Thomson obtained it was 
also from the jNIiddle Lias in the Bay of Lussay, four miles from Bradford, in the island 
of Skye, and again, from the island of Pabba. It varies considerably in size and in the 
number of its ribs, but is entirely similar to those found in England.

Shell variable in shape, transverse and obscurely subrhomboidal ; valves convex ; beak 
more or less produced and incurved ; hinge-line as long as the greatest width of the 
shell ; cardinal angles tapering into acute points ; area subtriangular and of moderate width ; 
fissure partly arched over by a pseudo-deltidimn. In the dorsal valve the mesial fold is 
formed of a single rib, to which corresponds a sinus in the ventral one. Each valve is, 
in addition, ornamented with from eight to twelve simple ribs, and the surface, besides 
being punctured, is covered with delicate spines. Dimensions vai'iable. Our Scottish 
example measured nine lines in length by sixteen in width. 
This species is here mentioned for the first time as a British fossil, and was discovered 
by Captain Bedford in the Bay of Caisaig, island of Mull. The Scottish specimen above 
described, agrees otherwise with M. Buvignier's type.

This is a common shell in the Middle Lias of the Bay of Caisaig, island of Mull, 
Scottish Jurassic Brachiopoda.
