1. ‘©On Streptelasma Remeri, sp. nov., from the Wenlock Shale.” 
By Prof. P. Martin Duncan, F.R.S., V.P.G.S. 
A great number of simple corals were found amongst the washings 
of Wenlock Shale prepared by Mr. George Maw, F.G.S., and most 
of them belong to a genus new to England, but which has been 
observed by Messrs. Nicholson and Etheridge at Girvan. ‘he species 
now described is allied to the Scottish form, but differs in having a 
fossula in the calice, a smaller septal number, and fewer dissepiments 
and tabule. ‘The author described the new species from sections and 
perfect corals, showing the great variability of the septal, and the 
persistence of the calicular arrangement, and explained the remarkable 
method of growth by increase at certain points of the calice only. He 
enlarged upon the variability of the same coral during growth, and 
noticed the bisymmetry of this coral. The relation of the double 
pinnation of the cost to the septa was noticed, and also the relation 
of a constant vertical pair of coste to the fossula. Agreeing with 
Messrs. Nicholson and Etheridge upon all material points regarding 
the diagnosis of Streptelasma, the author maintained that there is a 
true theca with coste and not a simple epitheca. With those authors 
he placed the genus in the Zaphrentide. ‘The morphological data 
indicate that transverse sections of Kugose corals are apt to mislead 
when taken alone as furnishing specific characters. 
2. “On Cyathophyllum Fletchert, Edw. and H., sp.”’ By Prof. P. 
Martin Duncan, F.R.S., V.P.G.S. 
This was a short communication explanatory of the finding of this 
coral in the Wenlock Shale with Streptelasma Remert. The author 
referred to his essay in the ‘Philosophical Transactions,’ 1867, in 
which he showed that the group of Palgocycli, Edw. and H., belonged 
to the genus Cyathophyllum—to the Rugosa and not to the Fungide. 
Milaschewitsch having associated the name of Kunth with that of 
the author in proving the non-Fungoid character of the group, it 
was explained that Kunth wrote in 1869, and that he had nothing 
whatever to do with the original work. The author alluded to his 
late researches into the nature of synapticula, read before the Linnean 
Society, and explained the probable cause of the error of the dis- 
tinguished French zoophytologists in their differentiation of Palgocyclus 
porpita. 
38. ‘On the Fossil Madreporaria of the Great Oolite of the Counties 
of Gloucester and Oxford.” By Robert F. Tomes, Esq., F.G.S. 
This paper is in continuation of the papers which the author has 
already published in the ‘Quarterly Journal of the Geological Society.’ 
The author called attention to the fact that there has been sometimes 
in the study of corals a confusion made between growth by fissiparity 
and by gemmation. If the former process result from the gradual con- 
junction of two opposite septa, so as to form a new divisional wall in 
the calyx, there is no risk of any such confusion; but if the separation 
has been by the formation of a constriction in the central part of an 
elongated calyx, this may be, and has been, confused with growth by 
gem mation. 
A large number of the forms here described by the author are in 
the collection of Mr. T. S. Slatter, F.G.S., and were collected near
