subs. (obsolete).—A name given, about the middle of the nineteenth century, to the district lying between Edgware Road and Westbourne and Gloucester Terraces and Craven Hill, and bounded on the south by the Bayswater Road, and subsequently including (HOTTEN) the Portman and Grosvenor Square district: facetiously divided by Londoners into ‘Tyburnia Felix,’ ‘Tyburnia Deserta,’ and ‘Tyburnia Snobbica’: it soon fell into disuse. [From a brook called Tyburn (properly The Eye bourn), which flowed down from Hampstead into the Thames.]
