REPORT—1854. 
On Crustacean Impressions from the Trias of Dumfriesshire. 
By Professor Harkness, F.G.S. 
It was well known that footprints of reptiles were abundant in the New Red Sand¬ 
stone of Dumfries. Those now exhibited were compared to leech-bites in form, and 
were believed to be left by crustaceans. They came from an upper bed of sandstone, 
quarried at Corse Hill, north of Annan, The layers were sometimes ripple-marked 
and channeled as if by rills of fresh water trickling over a shore. 
On the Anthracite Deposits and Vegetable Remains occurring in the Lo\c<r 
Silurians of the South of Scotland. By Prof. Harkness, F.G.S. 
These strata form the high land south of the Firths of Forth nnd Clyde, ami have 
‘general inclination to the N.N.AV. The highest beds tire on the northern side of 
the range; and consist, near Girvan, of limestone and sandstone, with fossils of the 
-Llandeilo rocks. To the southward, fossils arc rure; but near the lowest part ot the 
series, at Glenkiln, uioc miles from Dumfries, organic remains are found in bcdi f 
anthracite, resting on tfiOO feet of unfossiliferous purple and grey ennditoni* snd 
shales. The fossils ore Graptalites Sagittarius, Dipfot/rupsU* priitis, and D■ ran ,'- 1 *'; 
biphonotretu micula occurs with the Graptolites in a thin bed of black shale at ths 
base of the anthracitic beds. At Dufl-Kinncl, crustaceans of the genus DilkyrMt jrii 
have been found. These fossils do not account fur the carbonaceous matter in >- ,r 
black shales, but indications of u fuooids " have been found ; and it is supposed that 
nutch of the hydrocarbon of these beds has been lost through the influence of merits' 
meal forces. I ueoids of the nonera Pala/ochorda and Chondrites ore found in the 
rtpp e-marked flags of a much higher part of the series, north of New Galloway, 
unaccompamcd by anthracite, but associated with a zoophyte ( Proto-wrgulom) 
r cks ot Annelids. The anthracitic bods wore supposed to have derived Uicir car- 
Donaceous matter from sca-wceda floating like the gulf-weed of the present day.
