Genus SUBULITES ( Conrad ). 
Character. “ Subulate ; volutions wide, with a very oblique suture ; aperture approaching 
that of Terebra.” 
“ The exact form of the aperture is unknown, the base being imperfect.” 
The above description of this genus is copied from Mr. Conrad’s manuscript notes. The 
specimen figured (PI. XXXIX. fig. 5 a) , is the original one on which the genus has been 
founded. 
237. 1. SUBULITES ELONGATA. 
Pl. XXXIX. Figs. 5 a, b, c. 
Subulites elongata, Conrad in MS. Emmons, Geol. Report, 1842* pag. 392, fig. 3. 
Elongated, subfusiform or subulate ; spire rapidly ascending to an acute point; volutions 
six or more, flattened ; suture banded ; aperture longitudinally extended, narrow, contracted 
posteriorly ; surface smooth 1 
This remarkable species is easily distinguished by its elongated fusiform shape, and 
flattened volutions which are very oblique. The last volution is extremely elongated, con¬ 
tracting gradually below the centre, and terminating in an acute point. The aperture is 
narrow posteriorly, gradually enlarging to the centre, and contracting to the anterior 
extremity. 
In its usual condition, as casts of the interior, the banded suture is not observed ; but in 
a single specimen from Middleville, and another from Mineral Point (Wisconsin), the 
shell is partially preserved, and the suture distinctly banded. In both these specimens there 
are no visible surface markings, but these may have been obliterated by maceration.

Position and locality. This species is not unfrequent in the higher crystalline portions of 
the limestone at Watertown. It is extremely rare in other localities, and I have seen but 
two specimens from Middleville and one from Wisconsin, showing that it has a wide 
geographical range. (.State Collection, from Dr. Crawe.)
