Vol. II, Pt. I] VAN DENBURGH— GALAPAGOS TORTOISES 327 



tortoises of Duncan Island. Length of plastron 610 mm.; 

 width at front curves 300 mm. ; greatest width of shell 570 

 mm. ; length of indentation in plastron 340 mm. ; width 

 of indentation 320 mm. Some of the marginal plates were 

 loosely attached to the carapace. Some old dried grass from 

 the intestines could still be seen and several old plates of a 

 brown color but nearly rotted away were near the remains. 



2. — Bones marked X [C. A. S. No. 8129] from remains 

 so badly rotted away that no measurements could be taken. 



3.— Skull marked 8 [C. A. S. No. 8130]. No bones or 

 shell could be found near by. 



4. — Collected one shell with carapace and plastron in per- 

 fect condition [C. A. S. No. 8132], but no bones were found 

 with it. 



5. — Found one old shell which measured as follows: Length 

 of plastron 440 mm. ; width between front curves 230 mm. ; 

 greatest width of shell 410 mm. Several bones were near by, 

 shoulder bones and pelvis, but very soft and crumbling away. 



6, 7. — Saw two more skeletons all crumbled away so that 

 no measurements could be taken. 



8. — A shell in fairly good condition. Greatest width of 

 shell 523 mm. ; greatest length of shell 665 mm. ; distance 

 between front curves of plastron 270 mm. ; distance between 

 hind curves of plastron 310 mm.; width of plastral indenta- 

 tion 280 mm. ; length of indentation 340 mm. This was prob- 

 ably a male, as the indentation in the plastron is very promi- 

 nent with a ridge at the back as in the male Duncan tortoises. 

 Skull marked with a star [C. A. S. No. 8131] belongs to 

 this tortoise. The other bones were in bad condition. 



9. — One old carapace showed the following measurements: 

 length of carapace 670 mm. ; width between front curves of 

 plastron 320 mm. ; between hind curves of plastron 400 mm. 



10. — One old piece of plastron found. Width between front 

 curves 205 mm. 



11.— Bones and large shell collected [C. A. S. No. 8127], 

 marked with a rectangle. Four marginal plates still on the 

 front of the carapace. 



12. — One old skeleton in which the front curves of the plas- 

 tron measured 200 mm. 



13._One old skeleton. Greatest width of shell 405 mm.; 

 width between front curves of plastron 215 mm.
