INTRODUCTION g 



Family PHYLLODOCIDAE 

 Lopadorhynchus brevis, Grube. Lopadorhynchus krohnii (Claparede), var. sim- 



plex, var. nov. 



Family ALCIOPIDAE 

 Vanadis longissima (Levinsen). Greeffia oahuensis, Mcintosh. 



Vanadis formosa, Claparede. Rhynconerella fulgem, Greeff. 



Torrea Candida (Delle Chiaje). Alciopa cantrainii (Delia Chiaje). 



Callizona angelini (Kinberg). 



Family TOMOPTERIDAE 

 Tomopieris carpenteri, Quatrefages. Tomoptcris nisscni, Rosa. 



Tomopteris septentrionalis, Quatrefages. Totnopteris kempt, n.sp. 



Tomopterts cavallii, Rosa. 



Family TYPHLOSCOLECIDAE 

 Sagitella kowalewsMi, Wagner. Typhloscokx mulleri, Busch. 



Sagitella cornuta, Ehlers. Travisiopsis sp. 



Sagitella lobifera, Ehlers. 



The total number of benthic species or varieties is 220, belonging to 128 genera, and 

 of pelagic species or varieties 25, belonging to 17 genera. 



There are 2 new genera and 29 new species or varieties in this collection, and several 

 additions have been made to the number of species recorded from the colder waters of 

 both hemispheres. I see no reason to doubt the truth of the explanation adopted by 

 Fauvel (1925 A, p. 316), Gravier and others of the presence of the same or closely 

 alHed species at both poles. 



GEOGRAPHICAL DISTRIBUTION 



The table on pp. 10-17 i^ constructed to show where, and at what stations, the species 

 were found; to what extent the Polychaete faunas, as far as they are represented in this 

 collection, diverge or overlap in the several regions (South Georgia and the Falkland 

 Islands, Tristan da Cunha and the Cape, etc.) ; and how often any two or more species 

 occur at the same stations. Regarding the last, the practice by systematists of presenting 

 their data in some such easily accessible form should prove valuable to the student of 

 animal communities. 



The station numbers are not arranged in chronological order, but according to the 

 areas in which they occur, related regions being juxtaposed. A few species are without 

 record of station, and these are omitted from the table. 



Each species has a number, which is carried over to the left-hand side of the right- 

 hand pages. The numbers in the columns are station numbers.
