BEYER'S EBALIA. 147 



The first occurrence of this species on record is that 

 mentioned by Montagu, who received specimens from 

 Weymouth, where it was discovered by Mr. Bryer, to 

 whom Dr. Leach afterwards dedicated it. This distin- 

 guished zoologist subsequently procured it through Mr. 

 Prideaux from the Sound of Plymouth ; it is mentioned 

 by Mr. Couch in his Cornish Fauna as the only species he 

 had himself taken. I have received both sexes from Ex- 

 mouth, through the kindness of Mr. Buchanan ; and I 

 have a fine male specimen from Torquay, and a female 

 from Tenby ; for both of which I am indebted to Mr. 

 Bowerbank, by whom they were procured by dredging. 

 It occurs also in Mr. Bean's collection at Scarborough. 

 Mr. W. Thompson mentions its rare occurrence as an Irish 

 species, the only locality in which it has been found there 

 being Belfast Bay. Captain Beechey dredged it with the 

 former off the Mull of Galloway, in fifty fathom water. 



Nothing is known of the habits of this species, nor in- 

 deed of either of the others of the genus. Its occurrence, 

 as far as we have any data, has always been in deep 

 water.
