PKOCEEDINGS OF THE GEOLOGICAL SOCIETY. [Dec. 19, 



§ 2. Fossils occurring in the Lower Old Bed of Forfar mid Kin- 

 cardineshire. — With one exception (Stylonurus), which is in the pos- 

 session of Mr. Powrie, of Reswallie, the writer can produce from his 

 own cabinet the fossils enumerated in the annexed Table ; but there 

 are still many undeseribed Ichthy odontites and separated scales of 

 fishes, which it is believed indicate other new genera and species. 

 There are also unnamed species (if not genera) of the family of the 

 Eurypteridce among the Crustacea. It must not be forgotten that 

 in these rocks there is also a unique but fragmentary flora, of which 

 the only form at all resembling any recorded species is an organism 

 almost identical with that figured in plate 35. fig. 30 of ' Siluria,' 

 and which Dr. Hooker considers to be the spores of some cryptogamie 

 land-plant*. There are also forms in the author's possession about 

 which only a conjecture can be hazarded. From one locality slabs 

 have been procured containing imprinted on their surfaces all the 

 phenomena of a sea-shore of the period — Annelide-tubes, Annelide- 

 tracks, a great variety of Crustacean tracks, rain-prints, and desic- 

 cation-cracks.
