276 DISCOVERY REPORTS 



Hob. North and South Atlantic; Antarctic. 



In addition to the material collected by the ' Discovery ' and that in the British 

 Museum, I have examined another specimen, 135 mm. in length, from off Tearaght 

 Rock, Co. Kerry, S.W. Ireland, at a depth of 720 to 695 fathoms, kindly lent to me by 

 the National Museum of Ireland, Dublin. 



Apart from its more slender form, somewhat larger head and shorter anal fin, this 

 species is very close to B. antarcticiis .
