terior ambulacrum, same specimen as 1. 
3. Avalve 0.71 mm. Tridentate pedicellaria, midway between the actinal system and 
the ambitus, from the right anterior ambulacrum of a specimen 35 mm. in diameter, 
including the spines. 
4. A valve 0.66 mm. Tridentate pedicellaria, midway between the actinal system and 
the ambitus, from the odd anterior ambulacrum, same specimen as 3. 
5. A valve 0.84 mm. Tridentate pedicellaria, at the ambitus, from the left anterior 
ambulacrum, same as 3. 
6. Avalve 0.83 mm. Tridentate pedicellaria, midway between the actinal system and 
the ambitus, from the odd posterior interambulacrum, same as 3. 
7. Avalve 0.81 mm. Tridentate pedicellaria, near the actinal system, from the right 
posterior ambulacrum of a specimen 67 mm. in diameter, including the spines. 
8. A valve 0.85 mm. Tridentate pedicellaria, near the actinal system, from the left 
anterior ambulacrum, same specimen as 7. 
9. A valve 0.90 mm. Tridentate pedicellaria, midway between the actinal system and 
the ambitus, from the left posterior ambulacrum, same as 7. 
10. A valve 0.82 mm. Tridentate pedicellaria, at the ambitus, from the right posterior 
ambulacrum, same as 7. 
. A valve 0.47 mm. Tridentate pedicellaria, midway between the ambitus and the 
abactinal system, from the left anterior ambulacrum, same as 7. 
. A valve 0.74 mm. Tridentate pedicellaria, on the actinal side of the ambitus, from 
the right posterior ambulacrum, same as 7. 
. Ayvalve 0.41 mm. Tridentate pedicellaria, near the ocular plate, from the left anterior 
ambulacrum, same as 7. 
. A valve 0.14 mm. Triphyllous pedicellaria, near the actinal system, from the left 
anterior ambulacrum, same as 7. 
. Avalve 0.12 mm. Triphyllons pedicellaria, from the abactinal side of the ambitus, 
from the right posterior ambulacrum, same as 7. 
. A valve 0.11 mm. Triphyllous pedicellaria, near the apical system, from the left 
anterior ambulacrum, same as 7. 
The same valve in each pedicellaria is figured. The enlargement of the figures is about 
the same. All the figures present an exterior view.
