Professor J. W. Gregory — New Cretaceous Bryozoa. 61 



Sheet 23 (Scotland)", p. 39. Dr. Peach mapped a neck near East 

 Grange, b\ miles west of Dunfermline, the cross-section of which was 

 ascertained in underground workings.^ A somewhat similar case is 

 that of Knock Hill in the Saline Hills. ^ The vertical extension of 

 necks piercing the Calciferous Sandstone series has also been proved 

 in the shale mines in the oil-shale field west of Edinburgh. Mr. H. M. 

 Cadell ^ has described a remarkably good instance from the Broxburn 

 oil-shale workings near Philipstoun (West Lothian). At a depth of 

 120 feet below the surface a mine w-as driven from a level in the 

 Broxburn Oil-shale through tlie tufi" of the neck into the oil-shale on 

 the other side. The neck was 360 feet broad on this line of section, 

 and the oil-shale on approaching the tuff dipped steeply towards it on 

 each side. The walls of the neck were quite perpendicular and 

 somewhat slickensided, like the face of a fault. 



For information, and for giving us all facilities to examine the 

 stone-mine through the neck, we are indebted to Mr. Heniy Rowan, 

 general manager of the Fife Coal Company. 



Ill, — Neav Species of Cretaceotts Bryozoa. 

 By Professor J. W. Gregory, D.Sc, F.R.S., F.G.S., University of Glasgow. 

 rr^HE second volume of the Catalogue of Cretaceous Bryozoa in the 

 JL British Museum, of which the manuscript has been completed, 

 contains the description of various new Cretaceous species. Such 

 a catalogue inevitably takes some months in passing through the 

 press, during which it might happen that the species were anticipated 

 by description elsewhere. To avoid the risk of reduplication of the 

 names it is most convenient to publish the diagnoses. Fuller accounts 

 of the species, with illustrations, will be given in the Catalogue. 



MuLTiTUBiGERA, d'Orbigny, 1853. 

 Multituhigera sulcata,'^ n.sp. 

 Diagnosis. — Zoarium massive and thick. Eadial ridges of each zooecial sub- 

 colony short, thick, and ■\vedge-shaped. Apertures triserial to niultiserial at the 

 ends of the radii. The zocecial colonies are elliptical, and usually separated by 

 valleys or depressed porous areas, and not by definite regular laminse. 



Distrihution. — Senonian — Maastrichtian : Maastricht. 

 DiscoFASciGERA, d'Orbigny, 1853. 

 Discofascigera vinei^ n.sp. 

 Diagnosis. — Zoarium small, Avith a short, pointed base, covei'ed by epizoarium. 

 The upper surface is flat, with small raised marginal projections. In young zoaria 

 the apertures are sparse and widely scattered.

Fasciculipora, d'Orbigny, 1846. 

 Fasciculipora spicata, n.sp. 

 Diagnosis. — Zoarium with a narrow stem, widening into a thick horizontal 

 expansion, from which rise numerous short, blunt fasciculi. The zoarium seen from
