BRYOZOA FROM FRANZ-JOSEF LAND. 87 
The oral aperture has a small tooth on each side, forming a 
Sebizoporellidan aperture. 
Loc. Spitzbergen, 30-50 fath.; Barents Sea (D’Urban); Jan 
Mayen, 15-180 metres; Davis Straits, 100 fath. (H.); Gulf of 
St. Lawrence (4.); Shetland and Wick. 
Jackson-Harmsworth Exp.: off Elmwood 3 mile, 18 fath.; 
Giinther Sound, 10 fath.; nr. Wilezek Land, 127 fath. 
46. MICROPORELLA SPATULIFERA (Smtt). (Pl. 12. fig. 6.) 
Lepralia spatulifera, Smitt, “ Krit. Fort.” 1867, pp. 20 & 124, pl. xxvi. 
figs. 94-98 ; Lorenz, “ Oest. Polarstation Jan Mayen,” p. 89. 
There is one specimen from near Wilczek Land, and I have one 
in my collection trom the Gulf of St. Lawrence, sent to me by 
Canon Norman, and in both cases there is in many zowcia below 
the club-shaped process a tubular pore or perhaps avicularium, 
and it would seem that the species should be removed from 
Lepralia to Microporella. The shape of the aperture is that of 
Microporeila, and not of Porina. The zoccia and the ovicells 
are punctate, with one pair of stout spines and one pair of thinner 
ones above the oral aperture, and one or two small oval avicularia 
at the side of the aperture. The operculum is thin and does not 
show the subtriangular shape of the aperture, the distal end is 
round and the sides are nearly straight. Tne ovicell is not much 
raised, in fact sometimes not at all. ‘he wide club-shaped process 
is articulated. 4 
The specimen was so loaded with grains of sand, that it was 
hopeless to attempt to cut sections. 
Hincks in his papers on the St. Lawrence Bryozoa does not 
mention this species. 
Loc. Spitzbergen (Sm.); Finland (Sm.); Jan Mayen, 100- 
180 metres (Lorenz); Gulf of St. Lawrence (A. W. W. coll.). 
Jackson-Harmsworth Exped.: ur. Wilczek Land, 127 fathoms, 
on shell. 
47. ?Smirrra JacKsonit, nom. nov. (PI. 12. fig. 18.) 
Mucronella coccinea, Bidenkap, Bry. von Ost-Spitzbergen, Zool. Jahrb. 
vol. x. p. 624, pl. xxv. figs. 5, 6. 
Wherever it may ultimately be placed, it seems advisable that 
this Arctic form should be recorded either as a species or variety. 
In some points it differs decidedly from the British and 
Mediterranean Mucronella coccinea, Abild.; but it is waste of time 
trying to decide what Abildgaard meant, in consequence of his 
meagre description and figures.
