104 ALDER, ON NEW BRITISH POLYZOA. 
grown or nearly obliterated; but the upper portions are 
usually studded with prominent globular ovicells, giving them 
a knotted appearance. There is no authentic record of this 
species having been found south of Shetland. A smaller 
and more slender variety was also met with there by Mr. 
Norman. 
EscHARA LoREA,* n. sp. (PI. III, figs. 5, 6, 7.) 
Polyzoary yellowish white, shining, compressed, and dicho- 
tomously branched, rising from a slender flattened stem ; the 
branches are slender, much compressed, and strap-shaped, of 
nearly equal thickness throughout, expanding a little towards 
the ends, which are blunt, and generally bifid; the branches 
are pretty nearly on the same plane, and occasionally anasto- 
mose. Cells prominent, oval, nearly smooth, but appearing 
finely granulated under a magnifier, placed in quincunx, sel- 
dom more than two or three in a transverse row. Aperiures 
large, rounded above, and nearly straight below, with a 
slightly projecting, blunt rostrum, bearmg a circular avicu- 
larium on its upper and inner surface. A few small circular 
avicularia are also seen scattered on some of the cells, and 
there are punctures occasionally round the margin. Ovicells 
few, small, globose, slightly granulated, without perforations. 
Height, an inch to an inch and a half; breadth of branches, 
about +,th of an inch. 
One or two specimens of this new species were obtained in 
Shetland by Mr. Barlee, but being rather worn, they were 
passed over at the time as a variety of E. Skenei. Mr. Nor- 
man met with it at the same place in 1861, and again in 
1863, when he dredged fine specimens in eighty to ninety 
fathoms, to the north of Burraforth lighthouse. 
Ei. lorea is nearly allied to E. saccata of Busk, but it is a 
much more slender and delicate species, with the cells rather 
larger in proportion, less closely set, and fewer in a tran- 
verse row. ‘The cells in this species, too, have a distinct 
though blunt rostrum below the mouth, while those of E. 
saceata are not rostrated, but are uniformly cylindrical, with 
a much larger avicularium in front of the aperture. On the 
* JT had proposed to call this species E. ligulata, under which name it is 
mentioned (but not described) in the Report of the British Association ; 
finding, however, that the Celleporaligulata of Esper is also an Eschara, and 
synonymous with the E. fascialis of Pallas, I have thought it best to avoid 
a repetition of the name.
