Eroni off Ca[)o Mary llarnisworth, 53-93 I'athonis, there iis a 

 small specimen which is apparently /S*. incrassata, 8niitt, but the 

 determination of a small fragment is not satisfactory. The 

 zocoeia are about O'lS mm. internal diameter.

11. Stomatopora sp. 



I find mj^self unable to determine this Stomatopora, and con- 

 sider that a large number of the names of Northern Stomatopora 

 are only synonyms. There are many specimens from Eranz-Josef 

 Land without ovieells, the lobes are wide, the zoarium is flat, 

 and the ends of the large zooecia are but little raised. In zoarial 

 growth it most nearly resembles TabuJ/pora lohulata, Hassall ; 

 but why is T. lohulata, Hassall, to be generieally separated from 

 Stomatopora expansa, Hindis, and is nob Hiiicks right in his 

 surmise that this last may bo Prohosci)ia ramosa, d'Orb. ? 

 Stomatopora diastoporo/des, Hincks, seems to be separated on 

 very slight grounds. Tliis last, Smitt has called Diastopora 

 d/'astoporoidcs. 



The internal measurement of the aperture of the Eran^-Josef 

 Land spec nn ens is 0'13 mm,

A specimen from Giiuther Sound, gi'owing on Fhistra, is

 occurs, though in less satisfactory condition.
