This remarkable species resembles Boysia sinclairi, from the same beds, 
but has the spire less elevated, and the aperture reaching to the apex, 
instead of to the fourth whorl. It is also a larger shell. 
Only one specimen is before me, 
but it is possible that some of the 
very imperfect specimens referred 
to B. sinclair belong here. 
It seems advisable to regard this 
as a distinet genus of Bulimulide. 
It agrees with Boysta in many re- 
spects, but the aperture is different, and more like that of some of the 
neotropical genera, such as Zaplagius, especially Z. navicula (Wagn.). The 
orientation of the aperture suggests an alliance with Anostoma and Tomigerus. 
The species described as Boysia sinclairi and B. phenacodorum may be 
known as Grangerella (?) sinclairi (Ckll.) and G. (?) phenacodorum (CkIl.),, 
since they are more likely to be congeneric with the genus now described 
than with true Boysia. Specimens with complete apertures would enable 
us to place them more exactly. |

Three views of type. 
Eucalodium eophilum{n. sp. 
Shell (as preserved) broadly conoid, decollate, showing six whorls; whorls 
scarcely inflated; last whorl preserved strongly angulate at the 
periphery until about 7 mm. of the aperture, when the angulation 
is lost. Length 15.25 mm., width of last whorl 11, of penultimate 
whorl 9 mm.; length of aperture (measured obliquely) 9 mm. 
Surface of shell not preserved. In the apical region it can be 
seen that there is a spiral thickening, presenting a sharp edge

sp. Type. 
Sand Coulee Beds (Eocene); three miles east of mouth of Pat 
O’Hara Creek, Clark’s Fork Basin, Wyoming; Sept. 18, 1912 (W. Granger). 
Although this is evidently immature, and lacks the surface sculpture, it 
appears to be a true Hucalodium, related to the living E. decollatum (Nyst). 
The apex was doubtless decollate in life. 
Helix veterna veternior n. subsp. 
Alt. 11.5, max. diam. 17 mm.; whorls nearly five, last whorl large, broadly 
rounded, not keeled or angled; spire low, about as in Helix hortensis, which the whole 
shell resembles in shape; surface smooth, without any spiral lines, and with only very
