106 Canon A. M. Norman—WNotes on the 
Genus DoryporE.ta, gen. nov.¥ — 
Zocecia with front wall punctated, furnished with a median 
pore, in front of which is a spine with spatulate or pear- 
shaped head. Orifice somewhat horseshoe-shaped, being 
slightly contracted at the sides and the proximal margin 
quite straight, distal margin spined. Ovecia globose, punc- 
tate. Avicularia at the sides of the oral opening. 
Type, Doryporella spatulifera (Smitt). 
44, Doryporella spatulifera (Smitt). 
1867. Lepraha spatulifera, Smitt, “Kritisk Forteckning, &c.,” Cifvers, 
Kongl. Vet.-Akad. Forhand. p. 20, pl. xxvi. figs, 94-98. 
1900. Microporella spatulifera, Waters, “ Bryozoa from Franz-Josef 
Land,” Journ. Linn. Soc., Zool. vol. xxviii. p. 87, pl. xii. fig. 6. 
This is a very remarkable little species. The mother-cell 
is short, ovate, with spined margins. In young zoccia the 
pore is much larger in proportion than it is at subsequent 
periods of growth; it is wide open, and the spine rises from 
its anterior margin; in one instance I have seen this spatu- 
late spine forked at the extremity and of excessive length, 
At a later period of growth the pore is often covered over, 
sometimes with a yellow membrane, sometimes with a calca- 
reous lid. The oral opening has four spines, often of great 
length ; in one case the lower spines were forked at the 
extremity. In older zocecia an avicularium with oval 
mandible is placed high up on each side of the oral opening ; 
and in mature specimens the surface of the zocecium is 
granulated. 
On Hypothyris psittacea in Lang Fiord. Other specimens 
in my collection are from Gray Hook, Spitsbergen, 90 
fathoms, on stone (F. A. Smitt); “ Finmark” (fF. A. Smitt) ; 
Greenland, off Holsteinborg, 57 fathoms, on Hypothyris and 
Pecten islandicus (‘ Valorous,’ 1875) ; Greenland, on Hypo- 
thyris (from Copenhagen Museum) ; Gulf of St. Lawrence, 
on shell (Whiteaves). The species would seem to be 
especially fond of the shell of Hypothyris psittiacea as its 
dwelling-place. 
Forteckning, &c.” in 1874. In that paper he restricted the term “forma 
dura” to his figure 17, and called it Discopora cruenta (Norman). 
It was not, however, my Lepralia cruenta, and Hincks subsequently de- 
scribed it under the name Monoporella spinulifera (Ann, & Mag. Nat. 
Hist. ser. 6, vol. iii. 1889, p. 481, pl. xxi. fig. 3, and vol. ix. p. 152, but 
not var. preclara).
