In marking, this small species is a little like the well-known 
D. vidua Reeve, in comparison to which it stands a veritable 
pigmy. Two forms have been seen by us, differing in colour as 
follows :—-In what would be considered the type, an ashy 
brown is the prevailing hue, filletted round the whorls trans- 
versely with bluish white; in the other, a handsomer variety, 
a warm Ochre with flecking and median brown linear banding 
round the three last whorls, which are seven in number alto- 
gether. Form oblong, very solid, obtusely ribbed with fine 
spiral striolations, outer lip extremely thickened, inner simple. 
(Gevepwris, grave, sedate, from the sombre appearance). 
D. xanthoporphyria sp. nov. (Pl. IX., fig. rz). 
D. testa fusiformi, solidiuscula, parum nitente, anfractibus 
octo, quorum duobus apicalibus, brunneis, levibus, ceteris 
pallidé violaceis, apud medium flavida zona accinctis, ventrt- 
cosis, apud suturas crenulatis, longttudinaliter crassicostatis, 
costis obtusts, et spiraliter arcté filostriatts, apertura ovata, 
peristomate percrasso brunneo-strigato, sinu obscurissimo.
