10. ScRUPOCELLARIA ELONGATA (Smitt). 
Cellularia scabra, forma elongata, Smitt, “ Krit. Fort.” 1867, p. 284, 
pl. xvii. figs. 35, 36. 
Scrupocellaria scabra, forma elongata, Bidenkap, Bry. von Ost-Spitz- 
bergen, p. 614. 
There are two specimens from off Cape Mary Harmsworth, in 
one of which there is a distinct spinous process at each upper 
corner, and it wasat first marked “ bispinata ;” in the other the 
spines are only found on some zocecia. There is a small sub- 
oral avicularium to some zocecia and there are small lateral 
avicularia, no vibracula; in the specimen in which the spines are 
most developed there are a few scuta as figured by Smitt; the 
ovicell is elongate with a line down the middle and an area on 
each side, the radicle starts from near the base of the zocecium, 
the radicle-chamber being external; zocecium at the bifurcation 
acuminate. The jointing is low down as in Serupocellaria ternata 
var. gracilis (Pl. 7. fig. 12), and in this respect differs entirely 
from S. Smittii, Norm. (tigs. 8, 9), and is also much stouter than 
S. scabra, van Ben. There are 18 tentacles. 
Loc. Spitzbergen (Sm. & Biden.) ; Greenland, Finland (Si.).

11. Scruprocetrarta PEacuit (Bush). 
Cellularia Peachit, Busk, Ann. Mag. Nat. Hist. ser. 2, vol. vii. p. 82, 
pl. viii. figs. 1-4. 
Ina paper dealing with Cellulariide* I have stated my opinion 
that the genus Cellularia must be dropped, and that some species 
so placed belong to Serupocellaria. 
The differences between this and Serupocellaria ternata, var. 
gracilis, Sm., seem but slight, but as yet I have not had the 
opportunity of making sections of this species. The radicle 
arises from a chamber at the base of the zocecium.

Jackson-Harmsworth Expedition: small specimen off Cape 
Mary Harmsworth, 53-93 fath. 
Besides the species of Cellulariide already mentioned, Smitt 
gives Caberea Kilisit from Greenland, and Levinsen mentions 
Kinetoskias arborescens, Kor. & Dan., from Kara Sea [and 
Nordgaard gives Bicellaria Alderi, B., from Spitzbergen; also 
Menipea Normani, Nordg., from off the coast of Norway].
