D. reticulata (Renier), Bronn. B. C. 370, and v. 220, 
pl. 89. f. 3, 4. Med. 50- 100f. This ee name has been 
so long in use, that it may be unwise to change it; but as 
it was not accompanied by a description or figure, Brocchi's 
name echinata is in strictness preferable. 
D. hystrix, Jan. Bellardi, Mon. Pleur. foss. Piem. 613, 
t.4.£. 14. Med. 40-100 £. Not D. reticulata, var. formosa, 
which (although it has also a spiny sculpture) is much 
arger and not so slender, with proportionally more trans- 
erse ridges; and it especially ba: the apex conical an 
E alee the apex in the present species being twiste 
ds spirally striated, like that of Trophon. Forbes’s Pleu- 
rotoma reticulata, var. spinosa, may belong to either species; 
it was dredged by him (according to Reeve) off the coast of 
Nice, at the depth of from 5 to 40 fathoms. P. spinulosa of 
Risso and P. Paaran of De Blainville are evidently the
