DISTRICT. 

 By Herbert C. Chadwick. 



The specimens of Ophiuridas, or Brittle Stars, collected in 

 the dredging expeditions of the Liverpool Marine Biology 

 Committee, during the summer of the year 1885, and placed 

 in my hands for examination, include examples of six well- 

 known species, referable to five genera. None of the 

 specimens present features of special interest.

Specimens of this species were dredged from a muddy 

 bottom, at a depth of ten fathoms, in the Menai Straits, oflf 

 Bangor, during the cruise of the " Hyaena." Associated 

 with the next species it occurs in considerable numbers in 

 that locality. It was also found off Port Erin during 

 August. Mr. Byerley * records it as having been taken at
