pumilio, Sm., and H. caliginosa (Gould). The former is exceedingly 
minute ; the latter was first described from Tierra del Fuego. 
It will be seen that the Molluscan fauna of the beach is in the 
closest possible relation to that of the Cape Horn and Falkland 
Islands area. 
In the clefts of the rocks lives a small pink sea-anemone, the 
Bunodes kerguelensis of Studer, though Andres (‘ Attinie,’ p. 235) is 
disposed to regard it as a Sagartia. Attached to the mussel-shells are 
colonies of a little Hydroid, Hydractinia antaretica, Stud. (whose 
polymorphism is described as less complete than that of its European 
ally), and of a larger form, Coryne (?) conferta, Allm. On the same 
shells and on stones is a small Spirorbis. Of worms we have two 
peculiar species, Syllis myttlorum, Stud., among the mussel-beds, and 
Ophryotrocha Claparedi, Stud., among the green Alge at low-water 
mark. 
Of Crustacea we have abundantly in the pools, Spheroma 
(Exospheroma) gigas, Leach, with its semiparasitic Jais pubescens 
(Dana), both common also in the Patagonian region and in New 
Zealand. There are a few Amphipods, Hyale villosa, 8. J. Smith, 
Lysianax (?) kidderi, 8. J. Smith, and Atyloides australis, Miers, the 
last-named probably occurring also in Australia, A little red Copepod 
which has been identified by Brady with the northern Harpacticus 
fulvus, Fischer, but which, perhaps, deserves re-examination, is also 
abundant. 
2. The Floridean zone displays a vastly richer and more beautiful 
fauna. Here we begin to meet the characteristic Antarctic fishes of 
the genus Notothenia and its allies, viz. Chenichthys rhinoceratus, 
Rich., allied to C. georgianus, Fisch., discovered by the German 
expedition in South Georgia; Harpagifer bispinis, Rich., common in 
the Falklands and South Georgia ; and some seven species of Noto- 
thenia. Of this last genus, whose headquarters appear to be in the 
Falkland Islands region but which extends to New Zealand and the 
Aucklands, some species have a range coextensive with the genus, 
while others are so far only known locally: it is a genus of which 
new species are certain to be found. 
Of Tunicates, there are found in this region: a simple Ascidian, 
as yet undescribed, similar in size to the northern 4. canina; 
and two species of Colella, living attached to the stalks of the 
Floridez. 
Besides the Mollusca of the shore, we have here among others, 
Patella kerguelensis, Smith, a species akin to the variable P. aenca. 
Martyn, of Patagonia ; another Chiton, (. (Acanthochiton) castaneus,
