Special description. 
Schmidt has given an illustration of the Sponge in toto, but not 
of the spieules. He says that these are „Stecknadeln”. As they 
have not all the same shape and size, I have figured them on 
Plate IV, figg. 133—136. Fig. 133 represents one of the smal- 
lest, wich are very abundant in the rind, fig. 155 on the con- 
trary a fragment of the greater ones. Most of them are fusiform, 
but the difference in diameter at the top and in the middle is not 
always great. There are also transitions with very indistinet head 
atthetop. The type however is tr°. ac. f and the varieties: (tr°.) ac. f; 
Birne. (f), and (tr°.) ac. (f). 
If Thecophora ibla Wyv. Thomson is another species that remains 
. dubious, for this author has not given illustrations of the spi- 
cules. The shape ot the Sponge, being more elongated, can never 
be a specific character. I have several specimens of T’hec. semisu- 
berites, one broad and low another tall and high.
