PLATE XCIV. 



Conca,vum-zone. 

 Figs. 1, 2. — Sonninia dominans, 8. Buckman. 



Fig. 1. — Side view of an immature, wholly septate specimen, reduced to two- 

 thirds of natural size. The details of the inner whorls up to the o have been 

 drawn from the other (left-hand) side of the specimen, on account of better 

 preservation. Railway-cutting, Bradford Abbas. My Collection. (Page 435.) 



Fig. 2. — The suture-line of the same specimen taken at a radius of 90 mm., 

 showing the length and ornate character of the lobes, also L tetradactyloid on 

 account of bipartition of the outer lobule. This drawing is a copy from a 

 photograph. 



Figs. 3, 4. — Sonninia dominatktx, 8. Buckman. 



Fig. 3. — Side view of a specimen = Sonn. dominans S, page 323. Reduced to 

 two-thirds of natural size. The last part of the whorl — from the o onwards — has 

 been drawn from the other side of the specimen because of better preservation. 

 Bradford Abbas. Formerly in the collection of Mr. Darell Stephens, F.G-.S. 

 Now in my cabinet. (Page 392.) 



Fig. 4. — Two suture-lines of the same specimen taken at a radius — for the 

 first one — of 60 mm. They show practically symmetrical, short, tridactyloid 

 superior lateral lobes with isosceloid terminal lobules.
