of this variety of Spirorbis carhonarius was again reproduced by Dr. 

 "W. Rhind in a little work entitled ' Excursions illustrative of the 

 Geology and Xatural History of the Environs of Edinburgh ' *. 

 The first collective account of the Lower-Carboniferous fossils, as 

 previously stated, was that given by Mr. Salter in the Appendix to 

 the Memoir on the Geology of Edinburgh. The list of Invertebrata 

 comprised exactly one dozen species, of which two were Annelids, 

 viz. Spirorbis carhonarius, Murch., and Sp. helicteres, Salter, both 

 obtained by Mr. R. Gibbs in the Clubbidean Limestone, at the ex- 

 treme base, according to Prof. Geikie, of the Cement-stone group. 

 Sp. helicteres was originally described by Mr. Salter from specimens 

 obtained by the Rev. T. Brown, M.A., near Eifeness, and figured 

 and described in the latter gentleman's paper " On the Moun- 

 tain Limestone and Lower Carboniferous Rocks of the Eifeshire 

 Coast "f. 



Mr. Salter remarked on the unattached habit of this worm, and 

 stated that it occurs in distinct beds, hundreds grouped together, 

 yet without ostensible attachment to any other object than its own 

 species. The same remark will apply to its condition at Clubbidean. 

 In May 1870 Mr. C. W. Peach communicated a paper to the Edin- 

 burgh Geological Society " On the Discovery of Spirorbis carhonarius 

 (Murchison) in the Limestone of Burdiehouse, &c." t. The same 

 species was again found by Mr. J. Henderson on striated stems, like 

 Catamites, from a black shale in Eorrest Road, Edinburgh §. 



In a short article entitled " Palseontological Notes," contributed 

 to the ' Geological Magazine ' in July last (1877), I called attention 

 to a Spirorbis occurring in a band of limestone at the Oakbank Oil 

 "Works, near Mid Calder, which appears to be closely allied to S. 

 siluricus, Eichw. 



Crustacea. — We are again indebted to Dr. Hibbert for the first 

 notice of Ostracoda from this series of rocks. He named end figured 

 Cypris scoto-burdigalensis and Daphnoiclea, sp., from the Burdie- 

 house Limestone ||. The first of these has since been placed in the 

 genus Leperclitia by Prof. T. Rupert Jones, E.R.S. ; and the second 

 has been named by him D. Bibberti. Dr. William Rhind also 

 reproduced the original figures of these species % ; and Mr. Salter 

 recorded further localities where they might be obtained **. A very 

 interesting paper was published by Dr. R. Paterson in the year 1837, 

 44 On the Eossil Organic Remains found in the Coal Eormation at 

 Wardie, near Xewhaven " ff. After describing the plants, Dr. 

 Paterson mentions the Entomostraca, which, he says, are to be 

 referred " to the genera Cypris and Daphnoidea ." He adds, on 

 another page, " These microscopic crustaceous remains are
