Before commencing work I had at my disposal, in addition to the references 

 just quoted, slides given me some years ago by Dr. Vaughan labelled thus : — 



Zaphrentis dela7iouei. Z, Malahide. 

 Cyaihaxonia cornu. S. of fault, Malahide = Eush Slates. 

 Michelinia cf. tenuisepta. Rush Slates, Malahide. 

 Zaphrentis omaliusi, var. densa.. Carr. Zj Malahide. 

 Densiphylhmi. Malahide, S. of fault s Rush Slates. 

 (This is D. nodosum. See Proc, R. Dub. Soc, vol. xiv (N.S.), p. 556.) 



When the work for this paper was nearly complete, I was enabled, through the 

 kindness of Professor S. H. Reynolds, to look through part of Vaughan's Malahide 

 collection which had come into his possession. It is small, and contains nothing 

 I had not already found. Besides it is obviously not complete as, e.g., Endophyllum 

 burringtonense is absent. There is no key to the symbols he used, and I could only 

 correlate them with mine in a few cases. It may interest some if I set them out. 

 The second column contains correlations found on some of the labelled specimens.

It appears from this that the beds S. of Carrickhill fault were regarded as the 

 lowest in the exposure.
