1 have not had any opportunity of seeing Stimpson's work 

 (Invertebr. of Gr. Manan), so that I am unable to form any op- 

 inion as to the correctness of Smitt's conclusion that his f. Can- 

 dida is the form described by Stimpson as Lejmdia Candida. But 

 as Veeeiel*) classifies Stimpson's species as a Smittia, and also re- 

 marks that „this species has been entirely misunderstood by Smitt 

 and others owing to the imperfection of the original description", 

 it is certainly safest to give Smitt's form the designation which I 

 liave used here. 



Schizoporella stor mi, n. sp. 



PI. V, figs. 1, 2. 



On a stone form the North Cape (1894), a Schizoporella was 

 found, which I suppose to be a new species. The zooecia, which 

 were rather broad in proportion to their length, had a single row 

 of pores along the margin, together with a few small pores on 

 the frontal side (cf. flg. 1). No ooecia were present in the colo- 

 nies, but large avicularia were found under and a little to the side 

 of the oral aperture. The mandible was very pointed. The sur- 

 face of the zooecia was finely granulated and had weak radial 

 stripes. The zooecia were separated by distinct lines, and it may 

 be mentioned as a peculiarity that there is a crossline (1, fig. 1) 

 by the oral aperture. I think the species will easily be kept di- 

 stinct from others on account of the distinct opercular ribs (o. r., 

 fig. 2). I have this species both from the North Cape and Ham- 

 merfest. 



1 have taken the liberty of naming this species after the 

 manaaer of the zoological collection, V. Stoem, in Trondhjem. 



Schizoporella hexagona, n. sp. 

 PI. V, tigs. 12, 13. 



Formed a little crust on stone from Kvænangen II, 90 m. 



It is possibly this species which Smitt has illustrated on pi. 

 2.5, fig. 79-) under the name of Mollia vulgaris, forma ansata. 



It is easily recognized by its six-sided zooecia whose frontwall 

 is punctured, but not perforated. The zooecia are separated by 

 distinct lines. On my specimen there were neither oociea nor 

 avicularia. 



A characteristic feature of this species is the lai'ge proximal 

 lobe of the operculum (fig. 13). In the operculum b < h.

Kvamangen H, 90 m., on stone. 



^rhe zoai'ium formed a crust on a stone. In a dried state, the 

 iiuijority of the zooecia were of a deep red coloui'. The zooecia 

 liavo a few pores on the frontal wall, and between the pores 

 tlicrc are hollows (reminding one of a thimble). The ooecia, 

 which are nearly ball shaped, are fui-nished with deeper hol- 

 lows, but are not pierced. There were no aviculai'ia on the 

 colonies which I have had an opportunity of examining. The 

 IJi'oximal border of the oral aperture is straight witli a marked 

 sinus in the middle. 



The operculum has a lobe which answers exactly to tlic sinus 

 mentioned (fig. 4). In the operculum b > h.

In my list of Norwegian Cheilostomata I entered this spe- 

 cies as a Smittia, but on closer examination it became clear that 

 the species cannot be left there. Neither can it be considered to 

 be a Lepralia, as Hincks does. 



I at first thought of setting it up as the type for a new genus, 

 together with Smitt's Escharclla porifera, forma typica and the 

 one which I described as Smittia lineata, but on further consider- 

 ation, I have not ventured to start a new genus. In all three 

 species mentioned, there is a distinct sinus on the proximal margin 

 of the oral aperture, and notwithstanding that the opercula in 

 these tiiree species vary from that which is usual in the genus 

 Schizoporella, they have, however, at any rate a trace of a proxi- 

 mal lobe. Waters has described a form, ScMzoporclla harmsworthi. 

 from Franz Josef Land, which he has identified with S.mitt's 

 Escharclla legentili, forma prototypa. This can hardly be correct. 

 True, the mouth in young zooecia of forma prototypa may bear a 

 certain resemblance to the oral aperture in Watees' species, but 

 there is a groat ditt'ei'ence in the developed zooecia, harmsworthi 

 having a sinus on the proximal margin (cfr. Watees 1. c. pi. 9, 

 fig. 10), while forma jjrototypa has a mucro (cfr. Bidenkap, Bryo- 

 zoen V. Ost Spitzbergen, pi. 25, fig. 3, and also the present work 

 pi. IV, fig. 24). 



Besides, in haniixicorthi the ooecia are pei'foi'ated (cfr. Waters, 

 pi. 9, fig. 10), wliile in f. prototypa they are provided with hollows, 

 reminding one of a thimble. On the other hand, there seems to 

 bo complete resemblance between harmsworthi and Smitt's Eschar- 

 clla p)orifera, forma edentata, but as this form was raised to the 

 rank of a species by Hincks in 1877, harmsworthi must give way 

 to reticulato-punctata which form I consider, as does also Watees. 

 to be a Schizoporella. In one specimen from the Porsanger Fiord, 

 I could plainly see the oral glands at the opening of the tentacular 

 sheath, as illustrated by Watees.
