 1-13. Valves of Pedicellariae, seen from the exterior. 



1. A valve of a Tridentate pedicellaria, 0.86 mm. from the left anterior ambulacrum, near 



the actinal system of a specimen 73 mm. in diameter. 



2. A valve of a Tridentate pedicellaria, 0.91 mm. from the left anterior ambulacrum, close 



to the actinal system of a specimen 75 mm. in diameter. 



3. A valve of a Tridentate pedicellaria, 0.94 mm. from the left posterior interambulacrum, 



close to the actinal system, from the same specimen as 2. 



4. A valve of a Tridentate pedicellaria, 0.98 mm. from the right anterior interambulacrum, 



near the actinal system of a specimen 77 mm. in diameter. 

 6. A valve of a Tridentate pedicellaria, 0.99 mm. from the left anterior ambulacrum, close 

 to the actinal system of a specimen 80 mm. in diameter. 



6. A valve of a Tridentate pedicellaria, 0.94 mm. from the right anterior ambulacrum 



midway between the actinal system and the ambitus, from a specimen 82 mm. in 

 diameter. 



7. A valve of a Triphyllous pedicellaria, 0.13 mm. from the right posterior ambulacrum, 



at the ambitus, from a specimen 68 mm. in diameter. 



8. A valve of a Triphyllous pedicellaria, 0.14 mm. from the odd anterior ambulacrum, 



near the actinal system of the same specimen as 7. 



9. A valve of a Triphyllous pedicellaria, 0.13 mm. from the left posterior ambulacrum, 



midway between the actinal system and the ambitus of the same specimen as 7. 



10. A valve of a Globiferous pedicellaria, 0.22 mm. from the odd anterior ambulacrum, near 



the apical system, from a specimen 72 mm. in diameter. 



11. A valve of a Globiferous pedicellaria, 0.37 mm. from the right posterior ambulacrum 



near the actinal system of the same specimen as 10. 



12. A valve of a Globiferous pedicellaria, 0.22 mm. from the odd anterior ambulacrum, 



nearer the ambitus than the abactinal system, from a specimen 74 mm. in diameter. 



13. A valve of a Globiferous pedicellaria, 0.21 mm. from the odd anterior ambulacrum, mid- 



way between the ambitus and the abactinal system, from a specimen 83 mm. in 

 diameter. 

 The measurements of the diameter of the specimens include the spines. The dimensions 

 given of the pedicellaria are natural size. The corresponding valve was selected for each 

 figure.
