2. AGRIOPUS HISPIDUS, Jenyns. 
À specimen was dredged in April 1868, at Port Otway, Cape Tres Montes, where Mr. 
Darwin's specimen, the type of the species, was also procured. 
9. PRIONOTUS PUNCTATUS, Cuv. et Val. 
A specimen was taken in Rio harbour, swimming close to the surface of the water, in 
September 1867. 
4. AGONUS CHILOENSIS, Jenyns. 
A specimen was dredged at Port Otway, Cape Tres Montes, in April 1868.

5. APHRITIS.GOBIO, Günth. 
This species, described by Dr. Günther in 1861, in the ‘Annals and Magazine of Natural 
History” (ser. iii. vol. vii. p. 88), from a skin and an old stuffed specimen brought by that 
assiduous collector Captain P. P. King, from Port Famine, I met with severäl times in 
the Strait of Magellan and channels on the west coast of Patagonia. It has a most for- 
bidding and ferocious appearance when caught, opening its wide mouth and erecting its 
fins and orbital tentacles. The colours, when fresh, are as follows :—Above, dusky brown, 
sides paler, blotched with brown and orange-yellow. Under surface of head, breast, and 
belly orange-yellow. "Two points worth mentioning, and which were not observable in the 
specimens from which Dr. Günther drew up his description, are the existence, on the skin 
of the posterior part of each orbit, of a well-developed tentacle, more or less fringed at 
the extremity in different individuals, and of a row of branched cutaneous appendages 
attached to the under surface of the posterior margin of the scales on the sides below the 
lateral line, and resembling at first sight parasitic Lernæidæ. 
6. ELEGINUS MACLOVINUS, Cuv. et Val. 
This fish was taken in considerable numbers, in the seine, at Punta Arenas, Port Famine, 
and Port Gallant, in the Strait of Magellan, and formed an agreeable variety to the 
monotonous diet of preserved meat to which we were subjected. 
7. CHANICHTHYS ESOX, Günth. 
This species was described by Dr. Günther in the same paper with Aphritis gobio, from 
an old stuffed specimen also collected by Captain King at Port Famine. Several speci- 
mens were taken on fishing-lines by us at Port Grappler, on the west coast of Patagonia, 
and proved rather good eating. It was beautifully coloured when first taken, the sides 
being barred. with greyish black and fine iridescent purple. Several specimens of a 
Caligus, apparently undescribed, were found adheriug to the skin. These I propose 
naming Caligus chenichthyis. 
8. NOTOTHENIA TESSELLATA, Rich. 
Specimens of this species, previously obtained from the Falkland Islands, were met with
