YQLUTA. Luctator jun. 
TAB. CCCXCV11. 
Spec. Char. Ovato-elongated, acute, costated, 
crowned with one row of large and another 
of small, short, acute, spines, transversely 
sulcated ; columella with three or more 
folds ; lip often plaited within, its edge cre- 
nulated. 
Syn. Strombusdubius, Brander68 . V. Luctator 
Min. Conch. 115, /’. 1. 
A. handsome regularly formed shell, covered uniformly 
below the spines, with broadish flat furrows and minute 
longitudinal striae, or lines of growth ; the superior row 
of spines consists of small and irregular ones ; the last 
whorl is not ventricose. 
Very abundant at Barton : the only actual difference 
between the Voluta. dubia, and the Luctator fig. 64. of 
Brander, appears to consist in the plaits within the lip • 
a series of specimens from the figures before us, to figure 
1 of table 115. and even larger is easily obtained, in 
which most of the small and middle sized ones will be 
found to have plaited lips, while in the large ones the 
lips are smooth and thin, but even in these there are 
sometimes indications of plaits, especially at some dis- 
tance within the edge, leaving the only character very 
equivocal. Athough Lamarck quotes Brander’s S. Luc- 
tator, his V. musicnlis is a longer and quite different 
she!!, a circumstance we were not aware of, when we 
figured the former. Brander himself, or Solander, has 
confounded V. spinosa, which Lamarck has properly 
separated, and V. depauperata, above described, with 
Luctator, although they are both more ventricose, and 
have no furrows upon the upper parts of their whorls ; 
lor the contrary reason the V. spinosa /3 of Min. Conch, 
tab. 11 5. fig. 3. ought perhaps to be considered a species 
rather than a variety ; there occur however intermediate 
forms.
