Type specimen. — British Museum. Carapace of adult male. 

 Straight length 33 inches. Origin unknown. 



Distribution. — This tortoise probably is distributed through- 

 out the whole southern end of Albemarle Island. At Iguana 

 Cove it appears to be the only kind, but near Vilamil one finds 

 both Testudo vicina and Testudo gUntheri. 



Material. — This is one of the commoner species in collec- 

 tions. The Academy has six from Iguana Cove, ten from the 

 vicinity of the old Cobos settlement in southeastern Albemarle, 

 and forty-five from near Turtle Cove and Vilamil Mountain. 



Diagnosis. — No nuchal ; gulars paired ; fourth cervical ver- 

 tebra biconvex; front of carapace moderately high in males, 

 much lower than middle in females ; height at nuchal notch 

 less than 45% (31 to 44%) of straight length; difference 

 between percentages of heights at third vertebral and at nuchal 

 notch more than 9 (10 to 23); carapace not saddle-shaped, 

 not narrow anteriorly, width at margin of junction of second 

 and third marginals not less than 44% (44 to 59%) ; first mar- 

 ginals not greatly enlarged, not everted, their ventral surfaces 

 not vertical, their most prominent points separated by less 

 than 25% (13 to 24%) ; length over curve not less than 115% 

 (115 to 134%); usually less than width over curve; vertical 

 distance from lower surface of plastron to lower edge of lateral 

 marginals great, 6 to 10% ; general size large, straight length 

 to 49.5 inches; plastron moderately long, median length 66 to 

 87% ; plates generally striated ; pectorals forming a suture on 

 median line; eighth marginal plate not reduced, with well de- 

 veloped superior border; lower jaw and throat not marked 

 with yellow.
