page 172 note 1 With regard to this Crinoidal limestone it may be of interest to draw attention to the fact that Dr. Radde in one of his journeys in this region of the Caueasus very nearly anticipated by about thirty years Worobiev's discovery of these Triassic strata, for in the Tiflis Museum (Die Sammlungen des kaukasischen Museums, iii, Geologie, p. 171Google Scholar) there is a specimen collected by Dr. Radde from this very district, viz., from the “river-bed of the Matchubusta, a tributary of the Khod river, near Mt. Tkhach”.—F. O.
