" Among the numerous specimens collected by Mr. Masters of 

 this species, a striking variety occurs. It is of a beautiful bright 

 yellow color, with indications of a single reddish spiral line" (Cox).

" The coalescent porcellaneous bands on a darker ground, consti- 

 tute the most prominent feature of this pretty species, whose nearest 

 ally is B. trilineatus of Western Australia" (Cox}. 



The specimens before me (pi. 2, fig. 41) differ from Dr. Cox's 

 type in being perforate and stouter in form. There are 4| whorls, 

 the earlier somewhat irregularly, finely pitted, the rest strongly 

 granose below the sutures, elsewhere wrinkled. The color is tawny,
