Carlos was Whittlesey's camp assistant and head porter on the 1987 Maxwell/Whittlesey Expedition. He may have been Brazilian, Venezuelan, or a native of another South American country. Whittlesey spoke to him in Spanish. After looking into the Kothoga Hut, Carlos's normally black hair turned pure white. At Whittlesey's request and despite his own misgivings, Carlos left Whittlesey and returned with the expedition's specimen crates to Pôrto de Mós, to ensure they made it back to the museum.
