Overview
David and Dian encounter two lidis while crossing a broad plain on their journey toward Sari. At first the animals are so distant that David cannot distinguish their kind. As they approach, he describes immense quadrupeds eighty to a hundred feet long, with tiny heads on very long necks. He estimates that the heads stand about forty feet above the ground. Their movements appear slow, yet each stride covers enough distance that they travel faster than a walking person. This combination of scale and unhurried motion gives the episode a sense of size that does not depend on the animals attacking the protagonists.
Human riders become visible on the animals’ backs as the distance closes. Dian identifies them as lidis from Thoria, a land on the edge of the Land of Awful Shadow. She says the Thorians alone ride them and that the animals are found only beside that dark country. The profile retains this as Dian’s account, rather than converting it into an independently surveyed range map. An earlier comparison also calls the lidi hairless. The first novel supplies no exact colour, detailed foot structure, diet, breeding system or named fossil species. Its long neck and giant proportions do not by themselves establish that it is a particular real sauropod.
The surrounding geography is explained through the conversation prompted by their arrival. Dian places the Land of Awful Shadow beneath the Dead World, which she says hangs between the sun and Pellucidar. Perry’s later explanation calls it an inner moon moving so that it remains above the same region. David admits that he has not visited the country from which it is visible. These reported explanations give the mounts a specific fictional place of origin, while leaving the narrator’s knowledge limited. They are part of the invented hollow-Earth cosmology, not terrestrial astronomy or a claim that a real hidden habitat exists.
The mounts’ passengers turn an encounter with unfamiliar animals into a personal reunion. One rider signals peaceful intent with raised hands and dismounts when he recognises Dian. She introduces him as Dacor, her brother, ending David’s momentary misunderstanding of the greeting. The pair’s arrival follows David and Dian’s discussion of alliances between human communities resisting Mahar rule. The lidis therefore serve as transport connecting people and regions within the story, rather than simply enlarging its catalogue of dangerous prehistoric creatures. The scene establishes that they can carry people and approach travellers without an immediate attack; it does not demonstrate universal tameness or a complete domestication practice.
First appearances & development
The lidi is an invented animal of Pellucidar in At the Earth’s Core. Burroughs introduces its size through David’s observations and its home and use through Dian’s explanation. The first novel leaves a precise zoological identity unspecified, so its resemblance to a long-necked prehistoric animal is not treated as a documented external design influence.
Canon & continuity
Chapter IV includes the hairless comparison. Chapter XV supplies the approaching quadrupeds, estimated dimensions, riders, Dian’s account of Thoria and the shadowed country, and the reunion with Dacor. Observation, geographic report and astronomical explanation are distinguished here.
