1877.] ON THE FISHES OF THE ARCTIC EXPEDITION. 293 
bird is dead. This fact I have often noticed while preparing the 
skins of Eurypyga helias; and it is exactly the same with the 
feathers of Mesites variegata. 
I therefore suggest that the genus Mesites should be arranged 
in the Natural System next to Eurypyga and its near ally 
Rhinochetus. 
I may add that on examining the powder-down under a glass, I 
find the structure of that of Mesites nearly identical with that of 
Ardea cinerea. 
6. Account of the Fishes collected by Capt. Feilden between 
78° and 83° N. lat., during the Arctic Expedition 1875-6.

1. Corrus auapRIcoRNIs, L. 
A young specimen, 4 inches long, was found dead by Mr. Eger- 
ton on the beach in Dumbell Harbour (lat 82° 30'). No other salt- 
water fish is known at present to have been found at a higher lati- 
tude. In this young specimen the nuchal tubercles are only indi- 
cated; but having compared it with a specimen obtained on the 
English coast, another from Lake Wettern, and with two from Sir 
J. Richardson’s collection (the locality of which is not known, but 
which most probably were given to him by one of the previous arctic 
explorers), I have no doubt as to their specific identity. Dr, Liitken 
has excluded this species from his list of Greenland fishes (‘ Arctic 
Manual,’ p. 116). 
2. IceLus Hamatus, Kroyer. 
Previously known from Spitzbergen and Greenland, seems to be 
one of the most common fishes in the latitudes between 80° and 82°. 
Two specimens were obtained at Discovery Bay (81° 44’), three at 
Franklin-Pierce Bay (in 15 fathoms), and seven at Cape Napoleon. 
All these specimens were caught in the month of August, and were 
ready for spawning. 
3. CycLorTEerus spinosus, Mill. 
Previously known from Iceland, Spitzbergen, and Greenland. Two 
specimens from Cape Napoleon, and four from Franklin-Pierce Bay 
are all young, and interesting as showing the irregular manner in 
which the conical spines are developed. The largest of these young 
specimens is not quite 2 inches long; and the tubercles are much less 
numerous than in an adult specimen ; it is rough, and covered with 
minute spines. In a specimen 15 lines long only traces of the tu- 
bercles are visible on the skin. A specimen 12 lines long is quite 
naked, whilst another of the same size has the tubercles as much de-
