Unfortunately, even though there are 493 Pokemon as of the release of Pokemon Ranger: Shadows of Almia, there are not 277 Pokemon in the game and therefore not a Pokemon numbered 277. The Almia Browser goes up to R-267 (Regigigas). Even with the option of Wi-Fi events making an extra three Pokemon available, it still does not equate to having a Pokemon numbered R-277 in the Almia Browser.
