tical and contracted. The false synapticulae are large. The epitheca is granular. 

 From the same locality as the type.

Feddenia ttpica, Duncan. Variety 2. Plate XI, Figs. 6, 7. 



This variety is from the same locality as the type. The corallum is taller, and 

 still retains the general shape. The costse are very granular, and the granules merge 

 into those of the epitheca near the calice. Elsewhere the epitheca is minutely granular. 

 The higher orders of septa are not so decidedly higher than the others on the side of 

 the larger septa. The costse are very wavy on the side where they coalesce.

The corallum is free, tall, very compressed, with a small rounded base, which 

 curves up to a keel-like crest that reaches the calice at one of the ends of the elliptical 

 margin ; a corresponding but smaller keel exists at the opposite end, and passes straight 

 down to the base, which is gently curved sideways. 



The calice is contracted, shallow, elliptical, and crowded with septa, the larger 

 reaching into the small axial space. There are four cycles of septa, which are not very 

 granular, and which have the generic distribution. The costse project in sets, which 

 become more prominent near the curved end of the corallum at the calice, until the 

 terminal form a decided ridge or keel. Lower down, the costse become covered with 

 the broken-looking epitheca ; but they are still visible and subequal. Some pass 

 straight down from the calice, and others, after a space, take on an oblique course, 

 which gives a regularly wavy appearance to the sides of the corallum. The base has 

 enclosed an organism, and the costse have followed the growth of the enclosing structure 

 rather than that of the narrow peduncle-like end. 



Height of corallum 2^ inch. 



Breadth of calice -^ inch ; length of calice l-j^o inch.
