 the Fr. exp., 1837-40, under D'Urville.

 peak, about 2,100 ft. in el., marking the S. side 

 of the entrance to Stonehouse Bay on the E. side

 and surveyed in 1909 by the FrAE under Charcot.

 which lie about 2.5 mi. N. of Eta I. and mark the 

 N. limit of the Melchior Is., in the Palmer Arch.; 

 in 64°16'S., 62°55'W. The name Sigma, derived
