Testa modice elongata, subfusiformis, spira sat elata, alba, anfraetibus embryonalibus castaneo 
- 
maeulatis. Anfractus eirca 7 planiusculi, sutura distineta discreti, apieales 3, primus laeviusculus, 
sequentes costellis arcuatis in utraque directione seulpti, normales 3 liris latis spiralibus, interstitia 
duplo superantibus eincti, striis inerementi scabrosi; ultimus magnus, ovatus. Apertura ovata, basi 
subquadrangularis, labro externo tenui, regulariter arcuato, haud sinuato; columella supra strietiuseula, 
basi leviter contorta, callosa.

„Shell moderately elongate, somewhat fusiform in shape, the spire well raised. Colour white, 
the protoconch stained with chestnut. Whorls about 7, rather flattened, with a well marked suture. 
Apical whorls 3, the first being almost smooth and the others deceussated by arcuate, riblets. The 
remaining whorls are seulptured spirally by numerous flat, broad riblets, which (under a lens) are 
seen to be about twice as wide as their interstices, and to be crossed by lines of growth which give 
them a roughened or scabrous appearance. The last whorl is large; the aperture being somewhat 
square at the base and with no noticeable sinus; the outer lip thin and regularly areuate. The 
eolumella is fairly straight above, a trifle twisted at the base, and has a light callus on its lower 
portion.“

„Nearly related to Blanchardi, Dautz. & Fischer, but, from their figure, the present shell 
is more slender and the mouth is not so broad; also the interstices of the spirals are not nearly 
equal in breadth to the spirals themselves. — It is also akin to Dalmasi, Dautz. & Fischer, which 
was found with it. From that species itmay be separated by the form being less elongate, the base 
not being so pointed, but squarer, with a corresponding difference in the shape of the mouth. The 
spiral seulpture is of a different nature in the pressent shell and the zone below the suture in 
Dalmasi, marked by arcuate striae, is lacking in P. lüsitanica. In form the shell recalls Daph- 
nella pompholyx, Dall., but differs apparently in the spirals, judging from his figure.*
