Xanthophyllite, var. waluewite. — The rare brittle-mica xantho- 

 phyllite with its associate monticellite from Crestmore has recently been 

 described by the writer, 2 so only the main facts concerning the min- 

 erals will be incorporated here. Xanthophyllite was first described 

 and named by Gustave Rose 3 as a wax-yellow mineral in scales and 

 plates, occurring as a constituent of a talc-schist in the Shiskimskaya 

 Mountains in the Urals. Years later the green variety was found and 

 named waluewite by Kokscharof. 4 The waluewite or valuevite occurs 

 as a constituent of chlorite schist in the Nicolai-Maximilian mine, 

 near Slatoust in the Urals. These two occurrences are apparently the 

 only ones reported and in both cases the mineral was a schist con- 

 stituent. The Crestmore waluewite is a product of the contact meta- 

 morphism and occurs disseminated through the blue calcite. Masses 

 of the blue calcite speckled with the green waluewite were once very 

 plentiful at the quarry, but none is now seen. 



The waluewite occurs in hexagonal-shaped basal plates of a deep 

 grass-green color and vitreous to slight pearly luster. The plates are
