obtained during the Cruise of the ‘ Oceana.’ 17 
appears to be confined to British shores and as far north as 
Greenland. It occurs three times in this collection at 
depths of from 500 to 1670 fathoms. 
Gaétanus miles, Giesbrecht. (Pl. I. figs. 3, 4, 5.)

One or more of this readily recognized species occurred at 
17 stations, almost all being females, and the few. males 
found were immature. Noticing some slight variations 
between my specimens and Dr. Giesbrecht’s figures, I sent 
some to Dr. Giesbrecht for identification, and received from 
him the following remarks upon them. He says :—“I 
believe them to be identical with Gaétanus miles. There is 
resemblance in alJl specific characters I made out for G. miles, 
only the lamella on the basal joint of the maxillipeds is of 
somewhat different form, and there is a greater number of 
spiniform setz on the inner margin of basal joint of the 
fourth foot in your specimen. My specimens of G. miles 
eame from the Pacific, yours are Atlantic, so the named 
differences will be geographical varieties.”

Less plentiful than the preceding species, being found at 
seven stations and very sparingly. Like the preceding, it 
has been hitherto reported by Giesbrecht from the Pacific 
Ocean and by Mr. T. Scott from the Gulf of Guinea only ; 
so the known range of distribution of both is now widely 
extended.

Oue specimen only was found at Station 5 y—an imma- 
ture male,—at a depth of 1300 fathoms. As the first male, I 
believe, recorded, it is unfortunate that it should be immature. 
Giesbrecht’s previous record is the Pacific Ocean; so here 
again we have a widely extended range. 
Euchirella pulchra, Lubbock.

Two specimens only were found at depths of 920 and 
1370 fathoms.
