MyriotrocTiiis rinkiij Steenstrup. This species was met with in abundance 
in patches of sand on a stony bottom, in seven fathoms, at the anchorage in 
Domino Harbour ; it was also found commonly in fifteen to thirty fathoms 
at Square Island. Packard, 1 . c. p. 209. 
Semper establishes a new genus, JEchinosoma (/. c. p. 44), for a species of 
Holothuroid from Copenhagen, which he describes as new under the name 
of hispidum, quoting Eupyrgus hisptduSf Barrett, in doubt as a synonym. 
Semper doubbi whether Liitken’s genus Enpyrgm will bo found destitute of 
respiratory organs. If Barrett’s species bo really the same ns the one sent 
to him as such from Copenhagen, then it has three rows of feet and ru- 
dimentary organs of respiration.

tute of feet, the integument covered with calcareous scales, each with a
