XXVlll PREFACE 



Reptiles appear to have no other representative than a little 

 green Lizard {Liolcemus magellanicus) . 



Amphibia, as far as I am aware, are totally absent. 



Of the Fishes, Dr. A. Glinther observes that : — " In Marine 

 forms, many representatives of northern genera reappear : such 

 as the Spiny Dog Fish (AcantMas vulgaris), species of Raja, 

 Sehastes^ Agonus, Mugil, Ly codes, Merluccms, Myxine ; while the 

 northern Cottoids are replaced by forms similar in outward 

 appearance, but belonging to different families, namely Aphritis, 

 Eleginus, Choenichthys, BovicJithys, Dissostichus, Notothenia, 

 Harjjagifer. Other genera peculiar to this fauna are a Ray 

 (Psammohatts)^ Maynea allied to Lycodes, and one of Flatfishes 

 {Pleuronecttdos), a family which generally is poorly represented 

 in the Antarctic region. Most of these Fishes are edible, but 

 among them the Atherines {Athenm'chthys)^ misnamed Smelts, 

 take the first place." 



" As regards Freshwater Fishes, the Antarctic region generally 

 is poor in variety of types ; and Tierra del Fuego does not differ 

 from the mainland, except in being still more pauperized. The 

 two characteristic families of this region, the Haplochitonidce 

 and Galaxiidce. — of which the former are the analogues of the 

 Northern Salmonidce, and the latter of the Esocidce — are both 

 represented in the island, as far as we know at present, by four 

 or five species, all of which are of small or even very small size." 



Fishes above all others likely to impress travellers are the 

 beautiful delicate-looking Atherinichthys latidavia, so often 

 alluded to by voyagers, one of the very best Fishes I have eaten 

 in any part of the world ; and a Grey Mullet {Mugil), found 

 alike in the sea and in freshwater streams, and perhaps identical 

 with M. ceplialus of the northern hemisphere. 



Although I put myself to considerable trouble in collecting 



Spiders, I have only been able to determine the families of 



these"^. Families accounted for are : — Lycosidce (Wolf Spiders) ; 



TheridiidcB (Line Spinners); Archmdce ; Argiopidce (Orb
