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

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

 Atlantic sea-bed. Dr. Wallich sent me a drawing of one dredged up on 

 board the ' Bulldog' in 1860. 



t For " No. 27, &c.," p. 216 ('Annals,' 1874, vol. xiv.), sLxth line from 

 bottom, read " 42=862 fathoms. Chops of English Channel." 



X Holtenia Cnrpenteri has been described and illustrated by Sir Wy . 

 Thomson in the ' Philosophical Transactions ' for 1809 (vol. 159, pt. ii. 

 p. 701 &c.), who before leaving in the ' Challenger ' had had similar 

 illustrations lithographed of Hyalonema lusitanicum and Tisiphonia aga- 

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

 my report.
