 The Leyden Museura possesses four specimens of this 

 Sponge , all being in the dried state. The fibre is extre- 

 mely strong , especially in the stem , which is ramified , 

 so as to form a complex of branches , not unlike the top 

 of an elmtree.

I found in the Leyden Museum a Sponge from the Mo- 

 luccas , with a label : Spongia cannabina Esp. XLV. Ap- 

 parently the Sponge has been determined only from super- 

 ficial inspection. Now Schmidt, and Ehlers after him, have 

 demonstrated that Esper's Spongia cannabina is an Axinella 

 0. S. Our Sponge however possesses no axis , but is a 

 distinct Clatkna. The echinate position of the spin ed spi- 

 cules show this The Sponge is not ramified , but forms 

 a flat strip. The spined spicules are short and for the most 

 part not sharp pointed ; they are represented in the for- 

 mula by tr. tr. sp. The anchors are minute. 



I have named this species after Reiuwardt , who brought 

 it from the Moluccas.
