Notes on the British Species 0/ Zeugopterus. 369 



branched. The accessory portion of the dorsal and anal 

 usually consists of four branched rays. The inter-orbital 

 septum is raised, forming a sharp ridge along the dorsal 

 margin of the left orbit, but is only very slightly raised on the 

 upper side, its diameter being about a quarter that of the eye. 



A continuation of the posterior straight portion of the 

 lateral line would pass through the inter-orbital ridge. The 

 left pectoral extends a little beyond the curved portion of 

 the lateral line ; the right is a little shorter, but the difference 

 iu size is not so great as in Z. punctatus. The first ray is 

 slightly stronger than the others, and is unbranched, but is 

 not so long as those immediately succeeding it. 



The left pectoral frequently has ten rays, and the right 

 only nine. 



Scales on the left side strongly spinous, those on the right 

 being ciliated. Scales prominent on the under side of the 

 dorsal and anal. The skin on the coloured side bears 

 numerous filaments, which are irregularly distributed and 

 frequently pigmented. 



Distribution. — From the shores of Denmark, around the 

 British Isles, to the Mediterranean. 



This species does not appear to be recorded from the coast 

 of Norway. I have not met with it amongst specimens 

 examined from the east coast of Scotland, but on the west it 

 appears abundant in suitable localities. I have taken three 

 with one haul of the trawl in Loch Fyne. I have also met 

 with this species in the Kyles of Bute, on the shores of 

 Mull, and in the Gair Loch, Koss-shire. My specimens vary 

 from three to six inches in length.
