“…For this reason, the mature adult rareIy exceeds 18 cm, the maximum size reached by the ammocoete. The River and Brook lampreys constitute a "paired species" (Zanandrea, 1959~) consisting of both a proposed ancestral and a derivative species, of which there are apparently many examples in the extant lamprey fauna (Hardisty & Potter, 19716;Hubbs & Potter, 1971).…”

These lampreys used to go up the Volga as far as the city of Kalinin (now Tver) and the mouth of the Tvertsa River [10].…”

“…Since the characters developed by each of these non-parasitic or Brook lampreys are in general very similar to those exhibited by a particular parasitic species, Hubbs (1925) has suggested that they were derived from the latter group. In British waters, the only example of these so called "paired species" (Zanandrea, 1959) is that comprising the anadromous parasitic River lamprey, Lampetra firuviatilis (L.) and the non-parasitic Brook lamprey, Lampetru pIaneri (Bloch).…”
