is eighteen lines, there must be, at the margin, about one hundred septa. 

 In part of a weathered cup some of the septa run along the upper surface 

 of the tabulse nearly to the centre. This species is alhed to Z. Canadensis, 

 but differs in having the principal septa more developed, and in its more 

 irregular growth. The cup has not been seen. It is possible that this and 

 Z. Canadensis may belong to a different genus, perhaps to Omiyhyma.

Z. BELLISTRIATA, B., op. cit., p. 430.— Turbinate, gradually enlarging 

 from an acutely pointed base, moderately and sometimes irregularly 

 curved. There are about sixty septa where the diameter is one inch. Many 

 of these in the lower part, reach the centre, but above the height of two 

 inches (as shown by a pohshed section of a specimen), the central area is 

 filled with irregular tabulae. The cup, in a specimen four inches m length, 

 is eighteen lines in depth, conical, or much narrowed towards the bottom. 

 Surface with five strong, rounded septal ridges in the width of three 

 lines. On approaching the base these are more closely crowded together 

 than they are in the higher and main body of the coral. They are crossed 

 by fine engirdling strise just visible to the naked eye. Length of the largest 

 specimen observed four inches. Numerous small straight individuals from 

 one inch and upwards occur with the larger. Wreck Point ; H. R. Also, 

 in numerous localities in Div. 1 and 2, A. G.
