that for a long time I was at a loss to know what the specimens 

 were. The revolving riblets which so mark the adult shell are 

 entirely absent, and the whorls, instead of being most prominently 

 angulated at the lower periphery, are only angulated superiorly; 

 but the character which most disguises the young shell is its 

 stellate form. The fine transverse hair-lines which may be seen 

 between the transverse and longitudinal riblets of a fully grown 

 shell are closely and uninterruptedly packed all over the upper 

 surface of a young specimen. But for the deep sutural groove, 

 the figure represents a similar stage in the growth of Liotia sub- 

 quadrata, T. Woods. 



Turbo stamineus, Martyn. 

 (Plate XXXV., figs. 1-3.) 



Apex of one and one-half whorls, depressed, thin, semi-pellucid, 

 white, smooth, defined by a thickening of the shell and a loss of 

 the porcellanous appearance. Light reflected up the perspective 

 umbilicus may 1)0 seen shining through the apex. Greatest 

 diameter of the protoconch 1 -5 mm. 



The shell at the stage figured is generall}^ bleached a dull white, 

 but I have a specimen in which the ananeanic structure is varie- 

 gated with bright crimson and green, and ornamented round the 

 suture with light blue blotches. The specimen figured show^s the 

 commencement of the broad sutural clutter.
