Var. ecostata, Norman. 



Longitudinal riblets of upper whorls more nu- 

 merous than in the type, but very small and scarcely 

 raised, while on the body-whorl they are either 

 wholly absent, or in other cases only faintly visible. 

 Dublin Bay (from the late Mr. W. W. VValpole). 



10. Bela rufa (Montagu), = Pleurot077ia rufa, Jeffreys. 



Var. 1. lactea, Jeffr. 



Var. 2. semicostata, Jeffr. 



Var. 3. Ulideana, Thompson. 



Var. 4. Cranchii^ Brown. 



Var. 5. angusfa, Jeffr. 



Jeffreys states that Sars found this species in Finmark, 

 This is a mistake, as it does not occur in Norway or Fin- 

 mark ; indeed its range is unusually limited. It is not 

 recorded from the Mediterranean. 



Genus 2. Typhlomaxgilia, G. 0. Sars. 



1. Typhlomangilia nivalis (Loven).

Dredged by Dr. Jeffreys and myself off Unst, Siietland, in 

 120 fathoms, and by the ' Porcupine,' 1869, " N. of Hebrides, 

 in 170 f." * 



I have dredged it frequently in the fiords of West Norway, 

 and Sars has procured it as tar north as the Lofoten Islands. 

 It was dredged by the ' Travailleur ' in 1882 off the east of 

 Portugal [Locard). 



Genus 3. Spirotkopis, G. O. Sars. 



1. Spirotropis carinata (Philippi).

* Jeffreys does not give the station, and the exact depth is not 

 recorded for any station. The nearest is Stat. 0, 167 fathoms ; and if 

 that station is intended, it is nut within the British area.
