ing mucro in the centre of the lower lip, from within the base 
of which a process springs, which bends to one side, and forms 
with the inferior margin a kind of loop; a denticle on each side 
of the mucro; on the front of the cell a raised avicularium with 
pointed mandible. 
The species is liable to considerable variation. At times the 
mucro is much developed, and the surface of the polyzoarium 
bristles with the long spear-like processes. In other cases it is 
a mere tooth on the lower margin. The avicularia, which are 
generally very numerous, are occasionally wanting. L. bispinosa 
is very abundant in Torbay, and, when fresh, is of a delicate 
lilac colour. 
37. L. affnis, nu. sp. Pl. XII. fig. 2. 
Cells broad-ovate, minutely punctured, separated by lines; ori- 
fice orbicular, with a raised peristome, produced below ; three 
denticles within the inferior margin, of which the central one 
is the largest; on the lower edge an avicularium, placed 
transversely, with pointed mandible. 
On shell from Start Bay. 
This species bears a considerable resemblance in some respects 
to L. Landsborovii. The points of distinction are the shape of 
the cell, which is not elongate as in the normal Landsborovii, 
the smallness of the punctures, and their more irregular distri- 
bution, and especially the form and position of the avicularium. 
38. L. ochracea,n.sp. Pl. XII. fig. 3, 
Cells rhomboidal, separated by raised lines; surface reticulate, 
sometimes studded with prominent white granules; orifice 
orbicular, with a sinus on the inferior margin, a little below 
which is an oval avicularium, set somewhat obliquely, mandi- 
ble pointing downwards,—sometimes replaced by a very large 
spatulate avicularium, extending to the bottom of the cell; 
ovicell ? 
Colour of polyzoarium dull yellow. 
On a stone from 80 fathoms, coast of Cornwall. 
The oval avicularia vary considerably in size. In many of the 
cells they are replaced by the gigantic spatulate avicularia, 
whilst others are altogether destitute of these organs. 
I have an Australian species, which is probably identical with 
this form.

Cells oblong, disposed in radiating rows, and separated b 
‘ narrow lines; surface smooth and shining, with rather large
