Remarlxs : — The body is in all specimens covered with 

 various foreign substances such as sponge spicules, foraminiferan 

 shells, sand-gi-ains, etc. Sponge spicules and elongate fora- 

 miniferan shells are stuck in tlie skin and look as if they were 

 setae produced by the animals themselves. They make the handhng 

 of the animals anything but pleasant, as these needle-hke bodies 

 are apt to be left in tlie fingers. At present, there seems to be 

 some difference in the thickness of this coating in different 

 specimens and in different parts of one and the same specimen, 

 but this is probably due to the fact that the coating has been 

 more or less rubbed off since capture. The mouth is entirely 

 ventral, and although the tentacles are generally drawn in, they 

 are sometimes left extended. At the posterior end, where the 

 coating of foreign substances is especially thick, there is 

 a median vertical furrow, at the ventral end of which is 

 the cloacal opening. This is made plainer when the coating is 

 cleared off. 



Tentacles 20 ; but sometimes only 17, 18, or 19 of them can 

 be counted, probably due in part to the difficulty of counting
