This form somewhat resembled Schisoporella condylata. In a 

 dried condition, both forms had a brownish colour, which was especially 

 concentrated at the oral aperture. There was also considerable resem- 

 blance in the appearance of the zooecia, when the shape of the oral 

 aperture is disregarded; and the ooecia in both presented the same 

 raised lines. They cannot, however, be regarded as different stages 

 of development of the same species, and I will therefore give a short 

 diagnosis. 



The zooecia are separated by distinct lines or sutures, which are 

 also to some extent found on the ooecia (fig. 34). The frontal wall of 

 the zooecia, as also that of the ooecia, is coarsely punctured, but thei-e 

 are few perforations (fig. 33). The majority of these are arranged in 

 the form of a row of marginal pores on each side. There were no 

 avicularia to be seen. The shape of tiie oral aperture is that which 

 characterises the genus Eschara (Lepralia), but the operculum (fig. 35) 

 resembles that in Schisoporella. The species cannot thus be considered 

 to be a typical Eschara. The interzooecial connections are long pore- 

 channels, which also call Schizoporella to mind. It may perhaps be 

 regarded as a connecting or transition form between the two above- 

 named genera.

July, 1900, the neighbourhood of the winter haven. 



It seems certain that some incrustations from the neighbourhood of 

 the winter haven belonged to the species that I described from the north 

 of Norway. The little elevation below the oral aperture is not found 

 in the specimens from the 2nd Fram Expedition; but this was also 

 very frequently the case in the Norwegian specimens. The strongly- 

 marked ribs on the operculum are a characteristic feature. The species 

 is new to the west Arctic fauna.

resembled Smitts's drawings. There were marginal pores, and as a rule
