 sometimes globose ; rib* from thirteen to twenty-four ; areoUe 

 $in. long, and lin. apart ; spines from 4in. to 2in. long. North- 

 eastern Mexico, Ac. See Fig. 693, for which we are indebted to 

 Herr ft. Ad. Haage.jun. 



E. tnblflonu (tube-flowered). /I. large, rising from one of the 

 fascicles of spines ; tube very long, a little enlarged upwards, 

 brownish-green, scaly, each scale with a long tuft of slender, 

 flaccid hairs ; petals spreading, white, oblong, much acuminated. 

 Plant sub-globose, much depressed, umbilicated at the top. and 

 deeply cut Tnto about eleven very prominent, compressed, slightlv 

 undulated angles, which have live or six woolly tultercles, each 

 giving rise to a fascicle of six to eight strong black spines, from

E. Visnaga (Visnaga, among the Mexican settlers means a 

 toothpick), jt. yellow, numerous. Plant large, elliptical, many-

 long, the other three deHexed, shorter. A. 7ft. Mexico, 1847. 

 A plant of this species, which measured 9ifL in circumference, 

 and weighed one ton, was an inmate of the succulent house 

 at Kew, in 1846. From injury sustained during its convey-
