There is only one previous record of the occurrence of P. 

 echinulatns off the west coast of Ii-eland ; a single specimen 

 was found by the Fiyigal in 175 fathoms, 34 miles off Achill 

 Head, Co. Mayo. 



Vertical range. — 30 to 291 fathoms. Most authors give 50 

 to 60 fathoms as the normal depth. Off" the east coast of 

 Ireland it has occurred in 30 fathoms, and, as may be seen 

 from the above records from the west coast, it has been taken 

 on one occasion (S.E. 338) in at least 291 fathoms. This 

 constitutes a considerable increase in the known bathy- 

 metric range of the species, the previous greatest depth being 

 218 fathoms (Appellof, 1906).
