 long, 1-1^ ill- ill fliam.at the thickest part, with the lower part gradually 

 thickening upwards to or above the middle, and the upper part with 

 2-3 narrow neck-like constrictions between 2-3 dilated irregularly 

 orbicular segments not much longer tlian broad, 3-angled, glabrous; 

 angles wing-like, sometimes wavy, sinuate-toothed. Leaves rudi- 

 mentary, minute, scale-like. Spines unequal, 2-8 lin. long, in pairs 

 ^-| in. apart,' widely diverging, brownish -grey, on horny shields ex- 

 tending above the spines to the flowering-eye and also shortly below 

 them on the teeth of the angles, but not forming a horny border to the 

 base of the teeth. Flowering-eyes \\-Z lin. distant from the base of 

 the spines. Flowers unknown.

 base, armed with very long spines. Branches erect (*r ascending, very 

 deeply constricted into subsngittate-ovate or -reniform segments 

 2-3 in. long and 2^-3^ in. in diani., and probably larger^, 3-angled, with
