1. Teochosmilia vaeicosa, Beuss. Plate VIII, Fig. 11, 



This species was described by A. E. Eeuss in his description of the Corals found 

 in one of the Coralliferous deposits of the Older Tertiaries of the Alps at Crosara. The 

 Sind type is smaller than the European, but the shape is the same. The base is small 

 and pedunculate, the body is irregularly cylindrical, constricted here and there, and 

 the calices elliptical, shallow, and without a columella. The epitheca is distiuct, and 

 exists in some places as circular bands. The costse are distinct, well developed, and 

 correspond with the septa. 



The species is described and figured in ' Pal. Stud, iiber die alt. Tertiarschichten der 

 Alpen,' ii. Abtheilung, Wien, 1869, p. 22, plate xvii. figures 4-6.

2. Teochosmilia Oldhami, Duncan. Plate III, Figs. 6-11. 



The corallum is conical, much compressed, bluntly pedicellate, and often curved 

 near the base. The calice is a long ellipse in shape, is shallow, and has rather a 

 sharp edge. 



The septa are very slender, crowded near the margin, and long and less crowded 

 near the centre. There are four cycles of septa in nearly all the systems. The 

 larger septa and the next in size reach to the centre, a small axial space existing; 

 they are barely exsert, faintly arched, largely granular at the sides, and often slightly 

 wavy. The next septa, in point of size, reach midway, and between them and the larger 

 on either side there are usually three very small septa. There is no columella ; and 

 the endotheca is scanty. 



The costse are unequal in size, and correspond to the septa, so that there are in 

 many places three minute costse in a group, with a larger one on one side and a medium- 

 sized on the other. The middle of the three small costse is usually the largest, and they 

 are often wavy and subsinuous in their course. The larger calices are almost subcresti- 

 form at the ends of the coral, and may project a little here and there.
