Survey of Fishing-Grounds, West Coast of Ireland, 1890—1891, 



silvery, with black markings. Black pigment is present, chiefly in the form of 

 isolated chromatoiDhores, or small groups of chromatophores, but there is a dark 

 patch on the top of the head, as in the adult, and another at the base of the pelvic 

 fins. Eight small groups of chromatophores occur along the course of the lateral 

 line, and the base of each ray of the first dorsal and anal fin is decorated with a 

 black spot. The dorsum is finely powdered with small dark dots, while larger 

 ones occur on the gill -cover and at the caudal extremity. There is a groove along 

 the dorsum, from which arise the basal ridges of the nine rays of the first dorsal 

 fin. The sides are slightly flattened, and the ventral abdominal region is some- 

 what biconcave. Beyond this there is no trace of the polygonal shape (in section J 

 of the adult (cf Day, " Fish. Gt. Brit.," ii., pi. exxv., fig. 2).

A large specimen was trawled at 154 fathoms, 28 miles off Achill Head, on 

 20th April, 1891. 



Off the Inner Hebrides, Scotland, a few boats from the east coast carry on 

 a conger fishery in deep depressions of 70 to fully 100 fathoms. 



Group Mursenesccina, Giinther. 



A small eel, trawled at 144 fathoms, off Achill Head, forms the type of a new 

 genus and species, of which one of us has already given a description, now 

 reprinted with a few verbal alterations.
