* Stray, fully developed ancborates of this sponge (that is, with the 

 three arms united like a four-ribbed ellipse) are very common in the

 Thomson in the ' Philosophical Trau.^actioiis ' for l8t9 (vol. 159, pt. ii. 

 p. 701 &c.), who betbre leaving in the ' Challenger ' had had simihir 

 illustrations litbugrapiied of IJyahmcma lusitaninim and Tisiphonia aga- 

 riciformis; so no description of either of these sponges will do found in 

 my report.
