 Isl. : common on lava beds near the shore (no. 3144). Albe- 

 marle Isl. : Tagus Cove, common in tufaceous soil on the 

 lower parts (no. 3146) ; Villamil, abundant in loose ashy soil in 

 open places near sea level (no. 3145). Bindloe Isl.: com- 

 mon near the shore (no. 3147). Charles Isl. : abundant on 

 sand beaches (no. 3148). Chatham Isl. : Basso Point, com- 

 mon on the beach (no. 3149). Indefatigable Isl.: north 

 side, abundant on sand beaches (no. 3151); northwest side, 

 Baur; southeast side, common on sand beaches and to some 

 extent in dry open places in the interior (no. 3150). James 

 Isl. : Orchilla Bay, Baiir. Jervis Isl. : a few specimens were 

 seen at 950 ft. (no. 3152). There is much variation in the size 

 of the glomerules, these being large in some specimens and 

 small in others. The arrangement of the glomerules varies 

 from closely crowded to well separated. Some of the speci- 

 mens are without rigid setae, a character which such specimens 

 share with C. fusca. Endemic.
