This species, which is not uncommon in the counties of Chautauque and Erie, in the streams 
falling into the great lake, is more abundant in the western waters. I have never tasted their 
flesh, but am assured that it is very palatable. They are exceedingly active and vigorous. 
Until recently separated by Dr. Holbrook, two species have been confounded under one name.

Characteristics. Shell elevated, carinate. Head moderate, with yellow stripes and large 
confluent blotches. Size of the preceding. 
Description. Shell much more elevated than in the preceding species. First vertebral plate 
smallest, elevated in the middle, somewhat pentagonal ; the following three six-sided, and the 
last three-sided. A prominent dark-colored tubercle on the central line of the posterior verte- 
bral plate, projecting backwards, and almost imbricated over the next succeeding plate ; these 
tubercles are largest on the second and third plates, becoming effaced on the last. The other 
plates of the shell present nothing distinctive. Sternum oblong, elliptic, of six pair, and widely 
emarginate behind: The anterior or scapular pair small, triangular, with a small tubercular 
process at the outer angle ; brachial plates truncate, triangular ; abdominal plates largest, and 
united by lateral processes and an intermediate plate to the fifth, sixth and seventh marginal 
plates ; femoral plates four-sided, the posterior angle projecting beyond the lateral margins of 
the caudal pair. 
Color. Very much like the preceding, both in its general color and the distribution of its 
markings. Edge of the marginal plates yellow. Sternum of a uniform yellowish color. Head 
with numerous yellow lines, frequently forming one or more large rounded spots on the sides 
of the head. 
Length, 5:0 - 7:0.
