Bonncmaisonia asparagoides was procured from 27 fathoms, 

 and also came up in a free state. 1 have obtained this

 the vicinity of Millport, also in a detached condition, so 

 that its precise limit could not be determined. It is very 

 probable, however, that it ranges into deep water, as frag- 

 ments have been observed, since the above observation 



was made, entangled in the nets used by deep-sea trawling 

 vessels. The fragment of Dasya coccinea in the table from 

 28 fathoms was also observed on the nets used by trawling

 greater depths cannot he doubted. From the circumstance
