 PREFATORY NOTE. 



The collection handed to me for examination and report thereon was contained in 1G3 

 bottles, the contents of a few of which were in such bad preservation that they were 

 practically worthless for the purpose of identification. The collection of individual 

 species is not a large one, though there were great quantities of the more common 

 species. But few absolutely new forms were found ; these comprised a new genus 

 [Paralahidocera) and seven new species {Euchoeta similis, Stephus antarcticum, Xantho- 

 calanus antarctkus and A', nuignus, Ilaloptilus ocellatus, Faroella antarctiea, and Gaetanus 

 antarcticus). As such of these copepods as may be considered Antarctic were 

 collected within a small area, I have not deemed it necessary to occupy space by the 

 repetition of individual captures, which would l)e momitonous and of no particular 

 interest. The drawings have been made by Miss Marion Lees. 



The signs used in the following pages are B 1 and B 2 for first and second basals ; 

 Hi and Re for endopodite and exopodite ; SI for inner marginal and Se for outer 

 marginal spine (or bristle) ; Li for inner and Lc for outer lobe ; Th for thoracic 

 somite. As they were first used in Giesbrecht's great work, and have been subse- 

 quently often employed by others as abbreviations, the author has thought no 

 excuse necessary for their use here, in order to avoid the constant repetition of the 

 words " exopodite " and " endopodite," etc.

Until the expedition of the ' Belgica ' there existed no records of the collection of 

 Copepoda south of Kerguelen, except those of Dr. Brady, which referred to the 

 ' Challenger ' collections made from the south of Kerguelen to the pack-ice at 66° 29' S. 

 The collections made by the ' Discovery,' the ' Belgica,' and the ' Gauss ' form a 

 most important contribution to the planktonology of this southern region, and the
