Biological investigations of deep outer reef faces by manned submersibles and deep diving techniques have yielded collections and observations of a previously undescribed species of the West Indian genus Gramma, a genus of fishes usually referred to the family Grammidae or to
a more inclusive Serranidae. This fish is apparently a common and widespread element of the outer reef face fauna of the Bahama Islands and Caribbean area. The three species of Gramma tend to replace one another with depth with G. linki occurring generally below 60 m where it
occurs with G. melacara. Where G. melacara does not occur in the eastern Caribbean, G. linki can occur considerably shallower.
