CONULARIA, Miller. 
Gen. Char. A conical, hollow, univalved shell, 
divided Jby imperforate septa, mouth half 
closed. 
Only two species are known of this genus, therefore, 
but little can be said of its general form, that which is 
to be considered the type of the genus, is a straight four 
sided pyramid, ornamented upon the surface, and whose 
base is partly closed ; the septa occupy perhaps half the 
length ; they are convex towards the apex, and imper- 
forate, unless there be a very minute siphuncle in one of 
the angles. It has hitherto been found only in a fossil 
state. 
Mr. Miller, of Bristol, has very properly instituted this 
new Genus for the reception of a four sided fossil some- 
what resembling an Orthocera, but furnished with im- 
perforate septa and an inflexion of the lip, that nearly 
closes the mouth. It may perhaps belong to that family 
of Lamarck’s order of shelly Animals Crassipedes, 
which inhabit tubes (Conchif^res crassipedes tubicolees) 
and contains Teredo and some other tubiform shells, 
whose tubes are sometimes jointed.

Bp. Char. Foursided, straight, transversely sul- 
cated, and Longitudinally striated the four 
angles sulcated. 
In the centre of each side the sulci are bent, the 
spaces between them form very narrow ridges, and the 
longitudinal striae are most conspicuous within the hol- 
lows ; the furrows approach very close together near the 
base. Two of the angles opposite each other are longer
