 In the „Grundziige einer Spougien Fauna des Atlan- 

 tischen Gebietes ," it seems that Schmidt also wishes to 

 bring his Bcniera Jihidata under the Desmacidmae. In 

 such case it is evident that the Sponge must be a JDesmacodes. 

 Probably Bowerbank's Hal. Couchii is identical with it. 

 Bowerbank says in the description of his Hal. elegantia 



that »the nearest allied species is Hal. CoucJiii 



Fortunately the abundance of bihamate retentive spicula 

 in Hal. elegantia and their complete absence in Hal. Couchii 

 renders the discrimination of the two species easy and 

 certain." But in his description of Hal. Couchii, he says 

 that is has: „retentive spicula simple and contort, biha- 

 mate , minute and slender ;" he adds however „not very 

 numerous." And so the difference between the two spe- 

 (ues seems to be a quantitative, not a qualitative one. As 

 Bowerbank gives no illustration of his Hal. elegantia it 

 must however remain doubtful for the moment.
