The generic reference of this shell to Whitella must be regarded 
as provisional, until further specimens can be collected at the type 
locality. The absence of a strongly defined umbonal ridge, es- 
pecially toward the beak, is noteworthy. There is a superficial 
resemblance to Cuneamya. However, there is no evidence of a 
well defined escutcheon of the form found in Cuneamya^ nor of an 
anterior lunule. Moreover, there is no broad, undefined mesial 
sulcus. 
34. Whitella goniumbonata, sp. nov. 
{Plate /, Fig. 3) 
Shell small, short, subrhomboidal. Beaks nearly terminal, 
enrolled toward the hinge-line so as to produce a concave anterior 
area 11 mm. long along the anterior margin, and 2 mm. in width 
on the single valve. Present convexity of the single valve about 
5 mm. but the original form of the shell probably was more ventri- 
cose, producing a more prominent umbonal area and a greater 
width for the anterior concave area. Umbonal ridge, at its junc- 
tion with the cardinal slope, angular, the angle being sharply 
defined from the beak for a distance of about 17 mm. toward the 
lower posterior angle of the shell, and then becoming more rounded. 
Concentric striae rather faintly defined. 
The hinge area is not exposed in the specimen at hand. The 
generic determination is based upon the general appearance of 
the shell. It evidently belongs to the same group as Whitella ohli- 
quata, Ulrich, but the shell is relatively shorter with a less oblique 
posterior margin, and with a less oblique umbonal ridge. 
Length 24 mm., length from the beak along the umbonal ridge 
to the lower posterior margin 25 mm.; height posteriorly 20 mm., 
height at the beak about 17 mm.; extension of the shell anterior 
to the beak about 2 mm. ; convexity of the single valve about 5 mm. 
in the present state of preservation, originally probably 6 or 6.5 
mm. 
Type. From the same lot of specimens as those bearing the 
label Riviere des Hurons, and collected October, 1872, by Thomas 
Curry, and assumed therefore to come from the same locality, 
near St. Jean Baptiste, although the specimen here described does 
not bear a label. Preserved in the Paleontological collections, 
Geological Survey of Canada, Victoria Memorial Museum, Otta- 
wa, Canada. No. 8426.
