610 REPORT UNITED STATES GEOLOGICAL SURVEY. 



From Station 137, Mr. Muslibacli "brought in the following : 

 Euom/phalus luxus. 

 Productiis semireticulatiis. 

 Spirifer roclcymontanus. 

 Spirifer (Martinia) planoconvex a. 

 Mr. Muslibacli reports that some of the limestones were almost en- 

 tirely composed of masses of these fossils. These hills probably repre- 

 sent the western side of an anticlinal, the axis of which must he towards 

 the east side of Malade Valley. There may be a fault, but I saw no ev- 

 idence of it.
