and the consequent direction and shape of the aperture. 
It is more of the shape of C. bulbus than of any other spe- 
cies I know. It is, however, probably a young specimen. 
Crucibulmn pilifcrum n. sp. 
Shell covered with numerous erect tubular spines which 
are small towards the apex, larger towards the base ; apex 
small smooth, spirally recurved. 
Pliocene, Matura. Given as C. tubifer in ni}- previous 
list. It may be a variety of the next species, but its plicae 
are smaller, whilst the spines furnish an ea.sily-recognized 
character. 
Crucibulum subsuiuni n. sp. 
Strongly striate, rugose, somewhat irregularly oval ; stria- 
tions with a tendencj’’ to run in pairs. 
Pliocene, Matura. Allied to C. striatum Sa3’, under which 
name it appears in mj' paper on the Matura beds. 
Trochus decipiens n. sp. 
Topshaped, imperforate, ornamented by many spiral lines 
of moniliform granules ; whorls rather concave above, and 
bearing a rather broad angular keel on their lower portion ; 
base flattened, covered with lines of rather square granules, 
aperture subquadrate, wider than high, broadly angulate 
by the keel ; columella thickened, spreading into a callus 
over the umbilicus. 
Var. laticarinatus . 
Keel broader and higher, whorls deeply concave above, 
suture deeply impressed ; lines on the base .squamo.sely 
granular. 
Pliocene, Matura. As TrocJms granulatus in my list of 
1864.
