Tarn (1922), The Greeks in Bactria and India, p.100, explicitly criticises V.A. Smith: "Extravagant ideas have been put forward as to what Seleucus did cede [...] The worst has been that of V. A. Smith, who gave Chandragupta the satrapies of Gedrosia, Arachosia, Paropamisadae, and Aria on the strength of Pliny VI, 69, a historical absurdity of unknown origin." According to Tarn, Smith's idea that Seleucus handed over more of what is now southern Afghanistan is an exaggeration originating in a statement by Pliny the Elder in his Geographia VI, 69, referring not specifically to the lands received by Chandragupta, but rather to the various opinions of geographers regarding the definition of the word "India."

Tarn further refers to Eratosthenes, who states (in Tarn words) that "Alexander [...] took away from Iran the parts of these three satrapies which lay along the Indus and made of them separate [...] governments or province; it was these which Seleucus ceded, being districts predominantly Indian in blood. In Gedrosia the boundary is known: the country ceded was that between the Median Hydaspes (probably the Purali) and the Indus."

Mookerji, Radhakumud (1966). Chandragupta Maurya and His Times. Motilal Banarsidass Publisher. ISBN 978-81-208-0405-0: "By the terms of the treaty, Seleukos ceded to Chandragupta the Satrapies of Arachosia' (Kandahar) and the Paropanisadae (Kabul), together with portions of Aria (Herat) and Gedrosia (Baluchistan)."

According to Kosmin (2014), The Land of the Elephant Kings: Space, Territory, and Ideology in Seleucid Empire, p.33: "Seleucus transferred to Chandragupta's kingdom the easternmost satrapies of his empire, certainly Gandhara, Parapamisadae, and the eastern parts of Gedrosia, and possibly also Arachosia and Aria as far as Herat."
