THE FAUNA OF THE EXE ESTUARY. 331 



the dock for some time. One on the Dawn, after she had been lying 

 there two months, was four or five inches long. Whether the dock is 

 a regular habitat of Ciona we cannot say, not having any previous 

 records, but at Plymouth this year the same species is extremely 

 abundant in Millbay Docks, some of the specimens being as much as a 

 foot long, whereas formerly we have never found more than a few 

 small ones each year. Many of the Exmouth specimens were infested 

 with a large species of Copepod, Notopteroplwrus gibber.

 April and May, 1897. [E. W. L. H.] 



Trachinus vipera, Citv. and Val. A "sting-fish," probably this 

 species, was taken by professional seiners off Polesands. The specimen 

 was not examined. Two off Bullhill Bank, May, 1897. [E. W. L. H.] 



GoBius PtUTHENSPARRi, Euplmisen. Fairly common among the piles
