Fig. 404. Primary form with summits truncated. P on 

 = 122 40'. (base, HAUY.) Fig. 205. Primary, with the 

 summits replaced by three planes, which, if extended, would 

 lead to an obtuse rhomboid, s on 5=142 56'. (birhom- 

 boidal, HAUY.) Fig. 406. The same with Fig. 405, but 

 having the upper edges of the rhomboid bevelled by planes 

 n. nonn=128. (binoternaire. HAUY.) Fig. 407. n
