side downward and the antilices upward. Tarchomena and a large form with the tip gently curved have their antilici downward. These positions are undoubtedly due to the current action on the sea bottom. In zones 10 and 11 nearly all the fosils are gastropods. In fact gastropods dominated the life of zones 7-11. To feed these animals there must have been enough plant life more of which is now visible. Brachiopods are extraordinarily scarce, the commonest genus being Refinogonia and it is rare. Tripoli occurs not rare but it is not often that we pass an entire specimen and those occur nearly all in the top of zone 11. Large Asaphus are seen in fragments especially in zone 10 but also occur in 11. In the former zone we saw fragments indi- cating animals up to 12 inches long. Byzonia are practically absent and only one found in the top but did not see them in some abundance. Ostracoda and especially Lepiditris are very common in zones 10 and 11 and especially the latter. Crinoid stems occur only in the top of zone 11. They are very delicate stems almost thread like. As far as I can see all the zones from 7 to 11 are one continuous series of deposits. Zone 8 seems like Fort Carin and zone 11 (lower part) correlates best with the lower part of the Minjuan formation.
