414 Survey of Fishing- Grounds, West Coast of Ireland, 1890-1891. 



fish is known to habitually frequent rather deep-water, although, in the neigh 

 bourhood of Plymouth, it is tolerably abundant in depths of less than 30 fathoms 

 during the summer months. In 1887 * Mr. Cunningham artificially fertilized the 

 ovum on 15th August. 



Fam . — CORYPHiENIDiE. 



Genus Schedophilus, Cocco. 



Schedophilus medusophagus, Cocco. (Deep-sea.) 



Schedophilus medusophagus , Gijnther, " Trans. Zool. Soc. Lond.," xi., 1882, p. 233. 



The only known British example of this species was taken in a salmon net 

 at Portrush, Co. Antrim. We are not aware that there exists any record of its 

 occurrence at depths of over 100 fathoms, and, in including it among the deep-sea 

 forms, have been guided merely by the example of Dr. Giinther (Chall. xii. p. 46). 

 From the remarks of this author it would appear that the various species of the 

 genus are pelagic, though some possess structm-al characters indicative of a 

 bathybial habitat. S. mediisophagus has been obtained, in the adult condition, in 

 the Mediterranean and off Samoa, as well as on the Irish coast, while young 

 examples are common at the surface in Mid-Atlantic (Giinther). 



Fam. — COTTIDiE. 



Genus Cottus, Artedi. 



Cottus quadricornis, Linnseus. (Littoral.) 



Cottus quadricornis {'i), . . Holt, "Trans. Roy. Dub. Soc," N. S., v., p. 117. 



The addition of this species to the Irish list rests upon the doubtful identifi- 

 cation, by one of us, of certain very young Cotti, taken during the survey in the 

 outer harbour at Killybegs, in Donegal Bay, and off Tory Island. 



Fam. — TRIGLID^. 



Genus Trigla, Artedi. 



Trigla cuculus, Linnaeus. The Red Gurnard. (Deep-sea.) 



Trigla pini, Vaillant, " Exp. Sci. Trav. Talism. Poiss.," p. 360. 



A specimen is recorded by Vaillant from 164 fathoms (360 metres) in the Bay 

 of Biscay. The species is otherwise known only from littoral waters. Judging 

 from the results of the survey, it is only moderately abundant on the west coast 



of Ireland.
