This language was formerly listed as Lamalama (Y136) in this database, and this name is still used in many contexts. Three language , Mbarrumbathama (Y136), Rimanggudinhma Y195 and Morrobolam Y55, form a genetic subgroup of Paman known as Lamalamic. This subgroup is defined by shared innovations in phonology and morphology, specifically the development of voicing contrasts in trills, the setup of verbal inflections, and a number of innovative forms in nominal morphology. Within this subgroup, Morrobolam and Mbarrumbathama form a phonologically innovative branch, while Rumanggudinhma forms a more conservative branch (p.c. Verstraete 2018).
Mbarrumbathama, a clan name, is also known as Lamalama; Mbarrumbathama is the name of one of twenty clans associated with the language (Verstraete, 2018:3). Sutton refers to Lamalama as a cover term for Princess Charlotte Bay peoples (1993:32). In modern times many people at Port Stewart and Coen identify as Lamalama, but speak or identify with either Mbarrumbathama Y136, Rimanggudinhma Y195, Morrobolam Y55, Umpithamu Y50, and Yintyingka Y236.
Hale and Tindale say that 'Kokolamalama' (Y136) live around the Normanby and North Kennedy Rivers and Jane Table Hill (sic) and that they call themselves 'Bakanambia' and 'Wanbara' (1933:68). Capell (1963) lists 'Lamalama (koko)' and 'Wambara' as alternate names for 'Baganambia'. Tindale calls this language 'Bakanambia' and 'Kokolamalama' but notes that 'Wambara' is incorrect (1974:164). Oates and Oates (1970) call it 'Lamalama' but Oates (1975) uses 'Baganambia'. Laycock reports two dialects of Lamalama: Inland (see Y58) and Coastal; he includes a third Tablelands dialect on his map (1969:72, 97).
... from the Normanby River mouth around the margin of the lower bay to where the mangroves open up into sand beach west of the North Kennedy River mouth. Some of clans own countries somewhat futher inland too (Rigsby 1992:356).
