 Irish material must be deferred, and will accompany Dr. Matley's 

 forthcoming account of the Rush to Skerries section." ' 



The range of Z. delanouei seems more extensive in Scotland than in 

 the South- Western Province. A large number of specimens have 

 recently rewarded the diligent search of Mr. A. Macconochie ; these 

 were found at several horizons in the Cement Stones of Liddelsdale, 

 up to the base of the Fells Sandstone. The great majority were 

 dwarfed forms, in common with the associated fossils ; conditions 

 in these deposits seem to have been quite unfavourable to a free 

 development of marine life. The species also seems to occur at 

 a somewhat high level in the JS^orth of England. Some small corals 

 in Professor Garwood's collection from the Ashfell Beds, provisionally 

 correlated by him with the lower Visean level S^^-Sg, seem clearly 

 referable to Z. delanouei ; it is noteworthy that one or two associated 

 forms are intermediate in type between Z. delanouei and the 

 characteristic Visean coral Z. ennisMUeni.

External Chaeactees. 



Corallum conical, slender, and gently curved. The epitheca is 

 smooth without longitudinal ribbing, but usually with annular 

 striations and constrictions of growth, while an interruption of the 

 continuity of the epitheca through rejuvenescence is by no means 

 uncommon (see outline of Fig. 2, PI. V). Good figures of small 

 specimens are given both by Milne-Edwards & Haime and by 

 de Koninck. 



Calyx of moderate depth, bell-shaped in vertical section, with 

 closely-packed septa. 



The major septa are usually thin, always thickened at their outer 

 ends and usually also at their inner ends, which are fused together in 

 the centre of the coral. This may give rise to more or less elevation 

 in the centre of the calicinal floor ; but since the inner ends of the 

 counter septum and its neighbours are often not so affected, this

 in conjunction at Malahide, co. Dublin.
