This species much resembles C. atrox in general aspect, but 

 its spines are not so broad and compressed at their base, and 

 are of a more glaucous-yellow hue ; the form of the calyx corre- 

 sponds more with that of C. spinosa in being broad and little 

 constricted. The spines vary in length from 6 to 9 lines, are 

 greatly divaricated or nearly patent, and are decussating, the 

 internodcs being 4 to 6 lines apart. The leaves are 3 lines long, 

 Ij line broad, thick, coriaceous, convex and channelled above, 

 concave below, with revolute toothed margins ; each pedicel is 

 1 line long; the length of the calyx (including its reflected 

 segments, of nearly 1 line) is 3| lines, and its diameter 1^^ line*.

This species has a fuscous hue, with short interlaced spinelets : 

 the primary spines are 2 inches long ; the secondary 8-10 lines, 

 and 5 lines apart; the tertiary spinelets are 3 lines long, very 

 stout, with a sharp point. The leaves arc very caducous, and 

 are wanting in the specimen I have seen, but they are described 

 by Kunth. The flowers are small, of a reddish hue, many of 

 them appear sterile, and soon fall off; the segments of the border 

 are nearly as long as the tube, each being about 1 linelong; and
