MR C. TATE REOAN ON THE 



Dr. DciLLO, in whose liaiids the greater purt of the collection has been from 1905 until 

 March 1912. 



The identification of the Notothenioids and Zoarcids has proved a difficult matter in 

 the present state of our knowledge of these groups, and J have supplemented my report 

 by a monograph of the former and a revision of the southern genera of the latter ; 

 further, I have added some notes on the Galaxiidse and HaplochitonidtB, as their distri- 

 bution has given rise to some discussion. 



My work on the Notothenioids and Zoarcids is mainly based on the specimens in the 

 British Museum, including the Erebus and Terror, Cha/leiu/er, Southern Cross and 

 Diseorery collections, but I have been greatly helped by the loan of specimens from 

 the Museums at Paris, Berlin, and Stockholm. Thus I have been able to examine all 

 the species of Notothenia recorded by Vaillant from Graham Land, two of the tliree 

 species of Zoarcids recently described by Pappenhkim from Willielm Land, and 

 co-types of some of the Notothenioids described by Lonnberg. For their kindness 

 in sending me these fishes, and in giving me information about others that could not 

 be sent, I heartily thank Dr Pelleouin, Dr Pappenheim, and Dr Lonnberg. 



It need hardly be said tliat the fishes lend no support to the theory of bipolarity. 

 Most of the littoral fishes belong to the Nototheniidfe and related families, which are 

 characteristic of and peculiar to the Antarctic seas and the region immediately to the 

 north of them ; there are also several species of Zoarcidte, generically distinct from 

 the northern members of the family. Some of the pelagic and abyssal fishes are 

 Notothenioids peculiar to the Antarctic region ; others also, such as Notole^ns, Cynoma- 

 crurus, and Eu<jnathosau7-us, may not be found elsewhere ; but the rest belong to 

 widely distributed genera [Synaphohranchus, JJatliylagus, Myctophum, etc.) or even 

 species (e.g. Cyclothone microdon).
