 p. 358. 



? Axinella chaliuoides, var. cribrosa, Carter, A.M.N.H., Novem- 

 ber, 1886, p. 377. 



The sponge is branched, the branches being long and slender, 

 subcylindrical or flattened. The skeleton is reticulate, con- 

 sisting of strongly-developed horny libre, in part cored and 

 -echinated by smooth styli. In addition to the spicules mentioned 

 by Mr. Carter, I tind in B.M. sp. 39 and in B.M. sp. 42 and in 

 R.N. 310, slender toxa present. 



R.N. 310 (20 f; "dark brownish red"); ? 628 (x, 19 i; 

 "maroon ").

Ophlitaspongia nodosa, Carter, sp. 



Echinoclathria nodosa, Carter, A.M.N.H., November, 1885, 

 p. 356. 



This species is branching, witli the l^ranches nodulated and 

 sometimes anastomosing. The skeleton is reticulate, with well- 

 develojDed horny fibre. The spicules are smooth styli, in and 

 projecting from the fibre and scattered between. Special 

 echinating spicules can hardly be said to exist, and I have 

 .seen no microscleres.

 ;i very light wash of sepia ") ; 899 (s. 10).
