I.-SYSTEMATIC PART. 



i. THE ANTARCTIC FISHES. 



The collection includes examples of twenty -five species, twelve of which have been 

 described as new to science in a preliminary note (Ann. Mag. Nat. Hist, (8) XIII, 

 1914, pp. 11-14), four of these being new generic, types. This large proportion of new 

 forms is doubtless due to the fact that the bulk of the collection was dredged at depths 

 varying from about 50 to 250 fathoms. All but three of the species belong to the 

 group Nototheniiformes, and the additions to our knowledge of the genus Trematomus, 

 the Harpagiferinae and the Chaenichthyidae, are of considerable importance. A new 

 genus of the Bathydraconidae resembles the northern Cottid Icqlus in its armature of 

 spinate bony plates, and the first Antarctic species of Paraliparis is of interest.
