 1892. Astropeden irregularis, Scott, F.B. for Scot'd. Rept., No. 

 11, 1892, pp. 126, 127. 

 I have taken Astropeden irregularis at all the special stations except 

 II,, III., and XIV. It appears to be well, though sparingly, distributed 

 over the whole of the Moray Firth in from 6 to 42 fathoms. 



Its bathymetrical range in the British seas extends from 6 to 500 

 fathoms. It has also been taken in 1000 fathoms off the S W. coast of 

 Ireland. 



This species has been taken in the stomach of Cod, Halibut, and 

 Co7iger.

 1892. Luidia ciliaris, Bell, Brit. Mus. Cat., pp. 70, 71 

 Luidia ciliaris has been taken by me at seven of the sixteen special 

 stations in the Moray Firth, all of which, with the exception of Station 

 VI., are situated well off shore, and in not less than 17 fathoms. This 

 species appears to be fairly well, althougli sparingly, distributed through- 

 out the Moray Firth. I have not found it in the Cromarty Firth. It is 

 by far the more common of the two species of Luidia. 



L. sarsi is confined more to deeper water ; it has not been taken in 

 less than 26 fathoms. 



The bathymetrical range of Luidia ciliaris, so far as is at present 

 known, extends, in the British seas, from 8 to 55 fathoms. It has also 

 been taken in the Mediterranean at a depth of 87 fathoms.

 1892. Luidia sarsi, Bell, Brit. Mus. Cat., p. 72. 

 Luidia sarsi is by no means a common form in the Moray Firth. It 

 has been taken at four stations only, and never more than one specimen 

 at a time, being confined to the deeper water of the farthest oft'-shore 

 statious, where the bottom deposit is composed for the most part of a 

 gray coherent mud. 



Its bathymetrical range extends from 26 to 374 fathoms. 



HiPPASTERIAS.

Hippasterias j^hfggiana has been taken at eight stations, all in the 

 deeper water farthest from shore, in not less than 20 fathoms ; below this 

 depth it appears to be Avell distributed over the Avhole of the Moray 

 Firth. It has not been found in theCromarty Firth.
