Remark. Andres (1883) 

 and after him I myself (1893) have 

 placed this species together with 

 Rathke's E. clavata, on the suppo- 

 sition that the nemathybomes had 

 been overlooked by Rathke. After 

 having examined the Diiben and 

 Koren's species I think that it can- 

 not be identical with E. clavaia, be- 

 cause the nemathybomes in E. tuber- 

 culata are too large to be overlooked. 

 In fact it is impossible to identify 

 with certainty Edwardsia clavata with 

 any here described species, as Rath- 

 ke's description may be applied to 

 several Scandinavian species. As no 

 type-specimen oiE. clavata is known, 

 I think that E. clavata may be 

 dropped. I have not had the oppor- 

 tunity to see the specimens from 

 Molde nor those collected by Appel- 

 lof and by Grieg; probably most 

 of these belong to E. tubercnlata, at 

 any rate the specimen reproduced by 

 Appell6f(i89i) indubitably belongs 

 to this species. On the other hand 

 it is questionable if the specimens, 

 dredged in the Herlofiord from shal- 

 low water (6—12 fathoms) really, are this species, as E.iiiherculata seems to live in deeper water (compare 

 the occurrence).

Diagnosis. Physa distinct. Scapus with a well-developed periderm and 8 lines of rather large 

 but comparatively few nemathybomes. Nematocysts of the nemathybomes partly 36—65 X 2 (2.5 a partly 

 36—86 X 3.5—4-5 (5) /'- Tentacles 16, very seldom 12?. Nematocysts of the tentacles 17—23 X 2 (2.5) fi, 

 their spirocysts 14—17 n long. Nematocysts of the actinopharynx partly typical, 14—17 X 2 /i and 25—29 

 X 2.5—3 [i, partly with discernible basal part to the spiral thread, broader in the basal end 26—30 X 7 [i.
