to be seen in conjunction with a small shell of the genns Ostrea, 

 with Corallines, with plants to be referred to the genus Fucoides, as 

 well as with the multitude of terrestrial plants." William Hutton 

 contributed an article, " Note upon the Burdiehouse Limestone," to 

 the joint work by himself and Dr. Lindley *, in which he describes 

 the great abundance of the Cypris in that particular bed; he says, "we 

 find, in the utmost profusion, so as even in some parts to make the rock 

 almost oolitic, the shells of Cypris, with other minute Entomostraca 

 &c." Only two species of Ostracoda are mentioned by Prof. T. Rupert 

 Jones and Mr. J. W. Kirkby in their paper " On the Entomostraca of 

 the Carboniferous Rocks of Scotland " f , as occurring in the Bur- 

 diehouse Limestone, viz. Beyrichia subarcuata, Jones, and Leperditia 

 OJceni, Minister, although Prof. Jones added to these in 1871, in two 

 papers bearing the titles "On a new Locality for Leaia" J and " On 

 some Bivalved Entomostraca from the Coal-measures of S. "Wales." 

 Leaia was discovered by Mr. C. W. Peach in an ironstone nodule 

 at Wardie, on the Eirth of Forth, in the Wardie-shale section of the 

 Cement-stone group. In an Appendix to the second of the fore- 

 going papers a new Esiheria (E. Peachii) was briefly described §. It 

 was discovered by Mr.D. Grieve, F.G.S., at Camston Quarry, Arthur's 

 Seat, in beds referable, according to Prof. Geikie, to the upper portion 

 of the Red Sandstone group. The occurrence of both the Leaia and 

 the Estlteria were brought under the notice of the British Asso- 

 ciation in 1871, by Mr. C. W. Peach, in a paper "On additions to the 

 List of Fossils and Localities of the Carboniferous Formations in 

 and around Edinburgh" ||. At the same Meeting an interesting 

 discovery of " Fossiliferous Strata at Lochend" near Edinburgh 

 was announced by Mr. D. Grieve, who found, in an indurated shale, 

 plants and " a crustacean, Cypris scoto-burdigalensis, or an allied 

 species " %. 



Polyzoa. — I am unacquainted with any published notice of the 

 the occurrence of Polyzoa in the Edinburgh Lower Carboniferous 

 rocks. 



Brachiopoda. — In Mr. T. Davidson's paper on "Scottish Carbo- 

 niferous Brachiopoda," the only locality mentioned as yielding 

 brachiopods which can with certainty be referred to a Lower Carbo- 

 niferous horizon is the before-mentioned locality Wardie, where 

 Lingula squamiformis is obtained **. Mr. Salter also quotes it from 

 the same place ft. 



Pelecypoda (Lamellibranchiata). — Dr. Hibbert discovered a bivalve 

 in shale above the Burdiehouse Limestone, which he figured under 

 the name of Unio nuciformis %% ', it, with other fossils, was re- 

 produced by Dr. W. Rhind, and ultimately referred to the genua 

 Anthracosia by Salter §§. In 1838, Dr. W. Rhind published another
