Both the shape of the mouth and the opiTculuiii with its pi'oxi- 

 mal lobe, prove that there is a relationship to Sclu^opurdlu, (PI. V, 

 fig-. 32). It must, at any rate, be more correct to classify this 

 species as a Schizoporella than as a Smittina or Escharu (Lppralia). 

 The southern limit of the species which has been found up to the 

 present is Lofoten; its distribution is arctic.

Norman has taken this species in East Finmai'k, on 

 hWliaropsig rosacea, dredged off Vadsø. He remarks also (1. c.) : — 

 ., Other specimens in my collection are one received from Smitt 

 taken at Spitzbergen, and named Escharella auriculata; others from 

 the Gulf of St. Lawrence (Whiteaves), and off Holsteinborg, Green- 

 laud, in 57 fathoms.'" 



From this it will be seen that lincata has an arctic distribution, 

 <uid it is probable that what lias been stated to be Schizoporella 

 auriculata, Hassal from these latitudes should be transferred to 

 Uneata. The two species appear to be very closely allied, so that 

 it is easily explained that the arctic form (Uneata) is confused with 

 the more southern one (auriculata).

 this species under the genus Scliizoporella.

In his work on „the Polyzoa of East Fiimiai-k", iVora which 

 sevei-al quotations are taken in this paper, Norman lias given the 

 reasons for substituting Eschara for Hincks' genus Lepralia. The 

 synonyms for Lepralia polita may be found in my i)aper: — „Die

Tiiis species is particularly noticeable on account of its laigc, 

 wide zooecia (fig. 3), which are scantily pierced with small holes 

 in the sides. The oral apertui'e is partly surrounded by 4—6 short 

 spines. On the surface of the ooecium (fig. 4) there are fine punc- 

 tures, but they are not pierced through. The operculum (fig. 5) 

 is quite solid, and the muscle insertions are very distinct. 



It is probable that S:«itt') has this form in his paper of 1871, 

 under the name Discoporu meyastoma, for fig. 26 shows no slight 

 resemblance to the above mentioned species. I have, however, 

 given a new name, as I considei' that Smitt's Discopora metfastoma 

 includes two species, neither of them being identical to Lepralia 

 megastoma. Busk. (Cfr. Smitt's illustrations and description just 

 quoted with Ci-ag Polyzoa, p. 55, pi. 8, fig. 5).

The zooecia large, but not so broad as in the preceding spe- 

 cies. The front wall is perforated by conspicuous pores and there 

 are no spines on the edge of the oral aperture. Under the aper- 

 ture there is a protrusion (umbo). There are raised lines between 

 the zooecia (fig. 32) nearly all over. The ooecia are punctured, 

 but not perforated. The operculum is quite solid and has distinct 

 ribs (fig. 35). In fig. 33, it may be seen how these ribs lie against 

 the condyles of the oral aperture. 



It is not improbable that this species is included under Smitt's 

 definition Discopora megastoma. In Smitt's paper of 1S71, the figs. 

 24, 25 show no little resemblance to the above mentioned species. 

 In his description (1. c, p. 1129), Smitt also mentions a protusion 

 at the front of the zooecium. But there are hardly sufficient grounds 

 for supposing that this species is identical to Lepralia megastoma, 

 Busk. His species has, for instance, „a single row of channelled 

 pores".") On the other hand, there is a stronger resemblance 

 between Eschara nordlandica and Eschara (Lepralia) pertusa. Esper, 

 according to Hincks' characterisation of this species in Brit. Mar. 

 Pol. (1888), p. 305, pi. 43, figs. 4, 5. But the shape of the oral 

 aperture seems to be different, as well as the puncturing of the 

 ooecia. I think it is quite justifiable to enter it as a new species, 

 for I share the opinion that less hai'm is done by introducing a 

 new name for a known species than by classing two diffei-ent 

 species under an old name. 



The name Lepralia megastoma is used, in addition to the pla- 

 ces above mentioned, also by Lorenz'') and Bidenkap'*), the latter 

 also mentions the species as being a Mucronella. Hidenkap re- 

 marks that „die stark verkalkten Zooecien habeu die ganze Yor- 

 derseite mit grossen Poren durchlOchert", from wiiich it appeai-s 

 extremely likely that the species, which J^idenkap had before him 

 (from Spitzbergen) was E. nordlandica.
