122 ■ DISCOVERY REPORTS 



According to Treadwell's account the gills begin on the 5th somite (3rd chaetiger?) 

 and disappear at about the 58th somite: they have a maximum of 15 or more filaments. 

 In E. articulata Ehlers records the gills as ending between the 30th and 48th segments 

 and as having a maximum of 13 filaments. 



Ehlers again writes that the gills of his E. antiUensis extended from the 4th to the 

 40th foot and had a maximum of six filaments. Augener's specimens had gills extending 

 from the 3rd to the 55th feet with a maximum of five or six filaments. 



There is also much variation in the recorded relative lengths of the tentacles. In 

 Augener's specimens the unpaired tentacle reached to the loth chaetiger. Ehlers gives 

 the 20th segment (i8th chaetiger) for both his E. antiUensis and his E. articulata. 

 Treadwell gives the 8th somite (6th chaetiger) for the length attained by the unpaired 

 tentacle in his specimens, and in the present examples it reaches only to the 4th 

 chaetiger. 



The present species is characterised by the very long tentacular cirri and by the 

 great length of the dorsal cirri in proportion to the gills.

Remarks. A large specimen measuring 220 mm. by 9 mm. without the feet.

St. 91. 8. ix. 26. -5 mile off Roman Rock, False Bay, South Africa. 35 m. GearNRL. Bottom: 

 sand. Three specimens. 



Remarks. Three small and ill-preserved specimens, two of which are incomplete. 

 The complete example measures 38 mm. by i mm. without the feet and has about 

 80 chaetigers. The gills begin at the 3rd chaetiger, have about four filaments at the 

 8th chaetiger, rapidly reach their maximum number of nine to ten branches and dis- 

 appear by about the 35th chaetiger. Mcintosh's type specimen has from about the 

 30th foot onwards two yellow tridentate subacicular crochets : in these specimens there 

 is only a single tridentate crotchet to each foot. On the other hand, Mcintosh in com- 

 menting on a specimen dredged at 240 fathoms oflf the Cape {loc. cit. 1924) writes, 

 "a stout winged crochet," as if in that specimen there were only one. 



The jaws are well figured by Mcintosh. The dental formula is as follows: 

 6—7 •.-]+ 7—8. 



With the material at my disposal there is nothing I can add to Mcintosh's account. 



According to Augener this species is a synonym of E. aiistralis, Quatrefages.
