<P> Multiple morphological forms sometimes recognized as subspecies exist, including the mainland grizzly (Ursus arctos horribilis), Kodiak bear (U. a . middendorffi), peninsular grizzly (U. a . gyas), and the recently extinct California grizzly (U. a . californicus †) and Mexican grizzly bear (U. a . nelsoni †). On average bears near the coast tend to be larger while inland grizzlies tend to be smaller . </P> <P> The Ussuri brown bear (U. a . lasiotus) inhabiting Russia, Northern China, and Korea is sometimes referred to as the black grizzly, although it is a different subspecies from the bears in America . </P> <P> Meriwether Lewis and William Clark first described it as grisley, which could be interpreted as either "grizzly" (i.e., "grizzled"--that is, with golden and grey tips of the hair) or "grisly" ("fear - inspiring", now usually "gruesome"). The modern spelling supposes the former meaning; even so, naturalist George Ord formally classified it in 1815 as U. horribilis, not for its hair, but for its character . </P> <P> Classification has been revised along genetic lines . There are two morphological forms of Ursus arctos, the grizzly and the coastal brown bears, but these morphological forms do not have distinct mtDNA lineages . </P>
