BRYOZOA FROM FRANZ-JOSEF LAND. 79 
This may be the Hschara propingua, Smitt (pars), but his 
figures 181, 132, 134 can hardly represent the same species as 
figs. 126-128. 
Jackson-Harmsworth Exp.: off glacier between Cape Flora 
and Cape Gertrude, about 30 fathoms. 
37. Pornnua PLANA, Hincks. (Pl. 11. figs 11-13.) 
Porella Skenet, Ell. & Sol., form plana, Hincks, Ann. Mag. Nat. Hist. 
ser. 6, vol. i. p. 221, pl. xiv. fig. 6 (1888). 
Porella concinna, granular var., Hincks, Ann. Mag. Nat. Hist. ser, 6, 
vol. ix. p. 156, pl. vill. fig. 6 (1892). 
The zoarium is bilaminate, foliaceous, though in one small 
specimen from lat. 77° 55’ N., long. 53° 20’ E., 180 fath., there 
is only the creeping portion from which the colony arises. 
Hincks does not say whether his granular variety of P. concinna 
is foliaceous or encrusting. The shape of the zocecium and also 
of the secondary orifice is subject to great variation, and numerous 
round avicularia are scattered over the surface. In the younger 
_ zocecia there is an avicularium at the proximal edge of the 
aperture, and usually one on each side, more or less raised and 
turning inwards, with a few avicularia on the surface of the 
zoecium. In older zocecia these avicularia are within the 
aperture and there may be more than three; the surface is finely 
eranular with large pores round the border of the zocecium; the 
ovicells, which are also finely granular, are in some cases almost 
entirely concealed, in others are raised and globular. 
There are about 20 tentacles, avicularian glands, and also oral 
glands. 
I cannot agree in considering this a variety of P. Skene, and 
think it is entitled to specific distinction, though no doubt 
closely allied to P. concinna, Busk. 
Loc. Gulf of St. Lawrence, Trinity Bay, 96 fath. (Hincks). 
Jackson-Harmsworth Hxp.: Lat. 77° 55' N., long. 53° 20' E., 
130 fath., and also lat. 77° 55’ N., long. 53° 16’ E., 130 fath. 
38. PoRELLA SKENEI, var. PROBOSCIDEA, Hincks. (PI. 11. 
figs. 17, 18.) 
Porella proboscidea, Hincks, Ann. Mag. Nat. Hist. ser. 6, vol. i. p. 223, 
pl. xiv. fig. 4; Nordgaard, Bergens Mus. Aarbog, 1894-5, p. 25, pl. i. fig. 4, 
? Eschara verrucosa, Smit, “ Krit. Fort.” 1867, pp. 22 & 142, pl. xxvi. 
fig. 185. 
From off Cape Mary Harmsworth there are some specimens 
growing adnate upon Céellepora incrassata and Serupocellaria
