Distribution. This rather widely distributed species 

 has already been recorded off Australia, Sydney, 800 

 fathoms, by McCulloch. Otherwise, it has been "dredged 

 in plenty" in the Andaman Sea, 194-405 fathoms, in the 

 Bay of Bengal, off Ceylon, 224-284 fathoms, and in the 

 Arabian Sea, 142-430 fathoms (Alcock) (Lloyd), and 

 having been first described from the East Atlantic, 400- 

 1,200 fathoms (Milne Edwards), is well known from off 

 the coasts of Ireland, 250-627 fathoms (Kemp), the Bay 

 of Biscay, 400-500 metres (Caullery), off the Spanish 

 Coast (Wolf en den), and in the Mediterranean, 533-875 m. 

 (Adensamer, Riggio, Senna). 



It also was taken in considerable numbers by the 

 "Albatross" about the Hawaiian Islands in from 165 to 

 684 fathoms (Rathbun). 



Measurements. The "Endeavour" specimens of 

 Plesionika inartia f in length of body from the posterior 

 margin of the orbit to the tip of the telson of the extended 

 abdomen, range up to 90, 95 and 105 mm., though the 

 specimens with complete rostra do not exceed 66 mm. in 

 length exclusive of the rostrum; of these latter the 

 smallest is 47 mm. long.
