Tlxyone portlocldi, described by Forbes ('41) from a specimen found 

 by Capt. Portlock in Belfast Lough, Tvas regarded by Theel as- 

 possibly identical ydth.PhyUoph.orus drumniondi, but is believed 

 by Xorman ('93 a) to be a synonym of Cucumaria montagm 

 (Fleming), which, may be a distinct British species (Maren- 

 zeller in Ann. and Mag. Xat. Hist. (6) xii.. 1893 and 

 ISTorman '93 a).
