fathoms (Metzger). This species is not rare in the Forth 

 estuary, especially inshore, where the bottom consists of 

 muddy sand.

Habitat. — More or less frequent all over the estuary ; its 

 distribution appears to be somewhat irregular, due in part, 

 perhaps, to seasonal variation. My latest record of the 

 species is for Station V., where it was captured on 26th 

 April 1901.
