In 1925, Henry Cousens devoted a chapter of his book on the antiquities of Sindh to 'Baloch tombs'. He studied the tombs in Jarak (now spelt Jerruck), Sonda and Kharkharo, which were of the same type as Chaukhandi. Referring to the studies by G. E. L. Carter, he noted that more than twenty such cemeteries had been identified, and rejected the theory regarding above-ground burials, pointing to the frequent occurrence of arcade-like perforations in the lower casket. Cousens was the first to draw comparisons with other architectural monuments in Sindh, and he refers to similarities between the decoration of a tomb in Sonda and the tombs of Mian Ghulam Shah Kalhoro (Shah Wardi Khan) (d. 1772) in Hyderabad as well as the tomb of the Samma king, Jam Nizamuddin II (reigned 1461–1509), an impressive square structure built of sandstone and decorated with floral and geometric medallions. Comparable is also the mausoleum of Isa Khan Tarkhan the Younger (d. 1644) in the necropolis of Makli Hill. Regarding the covering of the tombs with "chattris" (cupola's or pavilions), he points to similar tombs in the same Makli necropolis and to the tomb of Mir Masum in Sukkur. He considered the tombs to be of approximately the same date as the tombs of Mian Ghulam Shah Kalhoro - i.e. the second half of the 18th century. Cousens pointed out that depictions of riders, as seen on some of the tombs, are also found on "sati" (shrine) stones in Kathiawar and Kutch.
