imens agree well with the figures given by Stanton, particularly 
with the form with the more elevated spire. From the upper 
sandy layers above the lignite. 
Turritella whitei, Stanton. 
Plate XXVIII, Fig. 6. 
The specimen figured is not well preserved but material 
discovered since the engraving was made show a shell of the 
size and characters of the Colorado variety of the species de- 
scribed by Stanton. 
The revolving striae are unequal and nodose and there are 
not more than five large ones separated by small hair-like ridges. 
Vanikoropsis tuomeyana, Meek and Hayden. 
Plate XXIX, Fig. 4. 
It is with considerable doubt that two specimens found as 
float in the Santa Fe marls west of Albuquerque mesa are re- 
ferred to this species. Meek states that the aperture is wrongly 
figured on his plate. Our figure is somewhat restored and the 
spire is probably higher than the cast would indicate. The 
shell is very thick and beautifully sculptured. There seems to 
be no doubt that the specimens are from the upper layers of 
the Fox Hills above the lignite. 
Priopsis bairdi, Meek and Hayden. 
Plate XXXIV, Fig. 6. ' 
We have but two specimens that can be referred to the 
present species, one being a cast of the interior and the other 
a nearly perfect shell, the surface of which, however, has been 
much injured by abrasion. 
In form and, so far as can be seen, in surface characters it 
appears to resemble P. bairdi more closely than it does P. col- 
oradoensis, Stanton. With the former it also agrees in coming 
from a high horizon associated with Fox Hills species. Sand- 
stone above lignite, east of San Francisco. Also at Carthage 
in sandy shales above the coal.
