An Arctic circumpokr species, locally abundant near the shore, and found by the 

 North Atlantic Expedition at Jan Mayen in 263 fathoms. 



Melanostigma, Gthr. 

 One species only is known. 



Melanostigma gelatinosum. 



Melanostigma gelatinosiim, Giinth., Proc. Zool. Soo. Lond., 1881, p. 21, pi. ii. fig. a. 

 ,, „ Goode and Bean, Bull. Mus. Comp. Zocil., 1883, p. 209. 



The typical specimen, 5^ inches long, was discovered by Dr. Coppinger in the Strait 

 of Magellan, in 24 fathoms. Recently this fish has been found off the coast of 

 Massachusetts in 395 fathoms, thus verifying the conclusion arrived at by the original 

 describer from its organisation, viz., that it lives at a greater depth than that at which 

 the typical specimen happened to be caught. But it is not probable that a fish so 

 eminently specialised for bathybial life as Melanostigma becomes " a shore inhabitant 

 in seas near the pole," as Messrs. Goode and Bean would have it.
