(From the ' Eec. Geol. Surv. Ind.') to show the affinity of this specimen with the tortoises of the Galapagos Island (fig. 14, B) and its difference from those of the Aldabra group1. This affinity is at once shown by the plate-like and curved form of the opisthotic, which extends behind the plane of the occipital condyle; and also by the narrow and slit-like form of the entrance to the labyrinth. The vaulting of the pterygoids is comparatively slight. The absence of a pit between the quadrate and the basisphenoid is alone sufficient to distin- guish this specimen from the cranium No. 39819 (p. 78). Cautley Collection. Presented, 1840. 1 The Mascarene tortoises, while nearest to those of the Galapagos Islands, have the opisthotics less produced Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
