meters from Ceara, and two specimens "from the State of Ceara" 



were sent by Mr. Rocha. All are identical except that the specimens 



sent by Mr. Rocha are somewhat bleached and show the brown 



markings very indistinctly. The variety, differs from 0. inflatus 



fasciatus P. and M., the common Odontostomus of the region, in being 



smaller and lacking the characteristic brown markings, and from 



0. inflatus costulatus Ancey in being smaller, with fewer teeth. 



Odontostomus (Cyclodontina) soabrellus (Anthony) Dohrn. var. cylindricus n. subsp. 

 PI. XXni, figs. 15. 16. 



A single dead specimen was sent to Dr. Branner by Mr. G. A. 

 Waring, of the Brazilian Geological Survey, "from the plains south- 

 east of Limoeira, State of Ceara, near the Rio Jaguaribe. " It differs 

 from the type by the much more convex lateral outlines of the spire, 

 which is therefore wider above, the contour of the shell being some- 

 what cylindric, while in scabrellus it tapers much more regularly; 

 the costulation is also decidedly finer than in scabrellus. It has only 

 four teeth, the sutural, suprapalatal, and basal folds of scabrellus 

 being absent, but this deficiency may be due to immaturity. The 

 whorls are 10; alt. 22.7,. diameter 7.5 mm.
