cess Royal Harbour, K. G. S., and I have noticed it commonly 

 on other parts of the south and west coast. It is almost impos- 

 sible to preserve specimens on paper, as the great quantity of 

 loose slime which the fronds contain rots the paper, and the 

 plant itself either decays or loses its characters completely. The 

 figure here given was prepared at King George's Sound, from 

 freshly gathered specimens. It is much softer than other Codia, 

 among which it perhaps comes nearest to C. adherens, from 

 which it differs in habit and substance. By roughly drying in 

 the sun an unwashed frond, I contrived to preserve a specimen ; 

 but all that I had attempted to keep in paper rotted, and were 

 thrown away. 



Fig. 1. Codium spongiosum, — the natural size. 2. Section through a lobe 

 of the frond. 3. Some of the peripheric ramuli. 4. Apex of a raraulus, 

 with young sporangia. 5. A ramulus with ripe sporangia: — the latter 

 figures variously magnified.
