"The bodies were buried underground in a makeshift grave near the hospital in the BDR headquarters compound," Col Rezaul Karim, deputy chief of the elite Rapid Action Battalion force, was quoted by AFP news agency as saying.
"The dirt had been covered with leaves."
Among the bodies found was that of Maj Gen Shakil Ahmed, who was chief of the BDR force.
Another 22 bodies were found earlier, including some that had been pulled from sewers and manholes.
Another officer, Brig Abu Naim Shahidullah, told private television station NTV that troops had found a number of mass graves and were "digging out dozens of decomposing bodies".
The assumption is that other missing officers were also shot by their men and that their corpses have been buried or dumped in the large drains that run underneath the BDR headquarters in central Dhaka, the BBC's Mark Dummett reports from the city.
Rank-and-file BDR members have long been angry over the fact that they earn about $70 (£49) a month, equivalent to the pay of a low-ranking government clerk, while their senior officers, in contrast, are relatively well-paid army officers.
They ended their mutiny on Thursday after tanks surrounded the barracks and Prime Minister Sheikh Hasina offered to consider their grievances.
The prime minister's son, Sajeeb Wazed, has told the BBC he believes that her handling of the crisis was a "triumph for democracy" in Bangladesh.
"This is probably the biggest incident Bangladesh has had since 1975 [when President Sheikh Mujib was assassinated in a coup] and our government - the prime minister - handled this compassionately, pragmatically but decisively to bring the situation under control," he said on the World Today programme.
