bearing two setae on the inner distal margin and two on 

 the apex, outer branch pyriform, arising from the middle 

 of the outer margin and extending considerably beyond 

 the apex of the inner branch, bearing four setae on its 

 outer distal margin and two on the apex. Caudal stylets 

 of moderate length, about twice as long as broad and 

 fully half the length of the last abdominal segment. 



Male. Antennules nine-jointed, sixth joint very short, 

 the others of moderate length, hinged between the fourth 

 and fifth joints and also between the seventh and eighth, 

 all the other appendages with the exception of the fifth 

 pair of feet are similar to the corresponding appendages 

 of the female. The inner branch of the fifth pair sub- 

 triangular in form bearing one stout plumose spine and 

 two plumose setae on its apex, the outer branch pyriform, 

 bearing three setae on its outer distal margin, and two 

 on the apex, with a strong plumose spine between the 

 two apical setae. 



Habitat, 1 mile off Spanish Head, Isle of Man, in 

 neritic material dredged from a depth of 16 fathoms ; very 

 few specimens were obtained. 



Bemarks. — This species differs considerably in shape 

 from Normanella dubia but the structural details are 

 almost similar to those on which the genus was founded, 

 the only differences being that the antennules have nine 

 joints instead of seven, and the inner branches of the 

 fourth pair of feet have three joints instead of two. These 

 differences are not considered to be of sufficient importance 

 to warrant the establishment of a new genus for its 

 reception.
