300 fathoms, and after trailino^ for two or three hours 

 " brought up many animals, some corallines, and a quantity 

 ot: sand, mud, and small stones .... and several entirely 

 new forms of creatures, of which accurate drawings'^ were 

 taken by Dr. Hooker "" (8, vol. i. p. 207). The voyage after 

 this was southward towards Franklin Island and away from 

 Coulman Island. 



After the first attempt to reach the Pole the vessels came 

 back to Tasmania, passed on to Port Jackson (Jnly 1841), 

 and stayed al)out three months in the northern extremity of 

 New Zealand (August-October 1841). 



They commenced a fresh attempt to reach the Pole in 

 November 1841, and traversed the Ross Sea a second time 

 in February and March 184.2. On February IGth, 1812, 

 they reached 75° S., 187° W. ( = 173° E.) , and in the afternoon 

 they hove to, and the dredge was put down in 290 fathoms, 

 and '' many curious invertebrate animals and a small tisli 

 were taken." The voyage was then continued southward 

 and Avestvvard, and the region of Coulman Island was left. 

 On the second attempt to reach the Pole they thus got 

 within 3° lougitude of Coulman Island (8, vol.ii. pp. 195-6), 

 but not so close to it as on January 20th, 1811. 



Fiom these data the conclusion may be drawn that if 

 Cephalodiscus nigrescens were then, as now, peculiarly 

 abundant in the neighbourhood of Coulman Island, the 

 specimens A-C were in all probability dredged either in 

 January 1841 or in February 1842, and from a depth of 

 about 300 fathoms. 



The species, however, as recent events show, is not peculiar 

 to that district, for on the second French Antarctic E.xpe- 

 dition (1908-10) Cephalodiscus iiigresctns was found in 

 abundance in the South-American part of the Antarctic 

 Ocean in lat. 68° S., long. 70° 20' W. Paris (2), a region 

 widely remote from the Ross Sea.
