better of it, and has begun wisely to grow a new tail, 
which is at present transparent, hut with a well-defined 
orifice. He lies half-buried in sand, and lias several times 
temporarily attached himself by his new tail.”* 
Since this page was in type, Dr. Hilton has taken a 
specimen at Bordeaux Harbour, Guernsey, which he has 
kindly transmitted to me. In its general characters and 
markings, it agrees witli the specimen described above ; it 
is, however, much larger, being at least five inches long, 
and three-eighths in diameter. The scajyus is more spindle- 
shaped, and more coarsely invected and corrugated ; the 
fihysa I have seen inflated, but slightly. The tentacles 
which correspond to the gonidial radii, and the pair at 
right angles to these, are much shorter than the rest. The 
dark gonidial radii have a flush of rich green. 
Many points in the form and anatomy of this genus 
indicate, as has been ably shown by Quatrefages, a decided 
approach to the Echinodermata, through such forms as 
Syrinx and Sipunculus.
