This is fig. 65 of Brander, andresembles, or is perhaps 
the same as Lamarck’s V. spinosa, although in the French 
specimens I possess, the whorls are blended into each 
other, and the lesser row of spines is more irregular ; it 
is besides shorter in proportion to the width. The neatest, 
whitest, and best preserved specimens at Barton Cliffare 
generally of this species, but the French specimens are 
frequently more perfect still, having the yellow lines of 
colour preserved. The variety 6 is more distant from the 
French shell; my figure of it shows the plaited columella, 
characteristic of the Genus, but which is mostly hid by 
the position of the shells in Brander’s beautiful figures. 
Fig. 4. is intermediate in form between fig. 2 and 3. My 
specimens of this species, and also of V. luctator, have 
all the outer lip so broken as not to show whether it be 
striated within or not, I therefore take that character from 
Brander’s descriptions. 
VOLUTA ambigua var. monstrosa. 
TAB. CXV.--- Fig. 5. 
Spec. Car. Shell elongated ovate, acute, with 
longitudinal undulations and sharp transverse 
strie ; spire crowned with two rows of obsolete 
spines. Aperture acute at the top, expanded 
at the base; outer lip dentato-striated within. 
Syn. Volutaambigua. Brand. Hant. 69. 
A much narrower shell than either of the last; that 
part of the whorl above the undulations, or ribs, instead 
of being concave as in them, is rounded, and has a trans-
