The figured specimen is from the coast of Belgium. This does not 

 entirely fit with the specimens from the Miocene of the Vienna Basin, 

 but may be left under this species for the present.

Si-phonina reticulata Cxjshman (not Czjzek), Carnegie Inst., Washington, 

 Publ. 291, 1919, p. 42. 



Test nearly circular, about equally biconvex, periphery subacute or 

 even somewhat rounded, compressed; chambers usually five in the 

 last-formed volution, not inflated; sutures distinct, not depressed, 

 limbate; wall smooth, conspicuously perforate; aperture elliptical, 

 with a distinct lip and short well-marked neck. 



Diameter up to 0.65 mm.; thickness, 0.30 mm. 



This species w^as originally described from the Miocene of the 

 gorge of the Yumuri River, Matanzas, Cuba. It is still living in the 

 general West Indian region. The young stages are carinate as shown 

 in Plate 14, figure 3, and resemble in general S. reticulata but in the 

 adult the peripheral carina is largely Jost and the sutures become 

 more limbate as in Plate 14, figure 2. 



The species ranges as far south as the coast of Brazil, and is widely 

 distributed off the coast of Florida and in the general West Indian 

 region in fairly shallow water.
