long. 7° 19' W. 515 fathoms. Temp. 45 •4° E. Mud. Two young 
S2:)ecimens without arms. 
Station 6. Lat. 59° 37' T4., long. 7° 19' W. 530 fathoms. 
Temp. 46°‘5 E. Grey mud. A fragment only. 
2. Antedon rosacea, Linck, sp. 
H.M.S. “Knight Errant,” 1880. In 53 fathoms on the plateau 
N.N.W. of Korth Eona. Lat. 59° 12' K., long. 5° 57' W. 
Eough ground. 
One mutilated individual was obtained here. It closely resembles 
the “ Porcupine ” variety from an unknown locality, both of them 
having the first brachials shorter than usual and a better developed 
backward projection of the second brachials. The “Porcujjine” 
specimen, which is the better preserved, has a somewhat more 
robust appearance than is generally presented by this species, and 
looks altogether as if its habitat were in the cold area. 
3. Antedon petasus, Dub. and Kor., sp. 
A single but tolerably perfect example of this well-known Scandi- 
navian type was obtained by the “ Triton ” at a depth of 87 fathoms 
on the Eaeroe Banks (Dredging Station Ko. 3. Lat. 60° 39' 30'' 
W., long. 9° 6' W. Sand and shells. Temp. 49° E.). It was officiat-

H.M.S. “Triton,” 1882. Station 2. Lat. 59° 37' 30” K., long. 
6° 49' W. 530 fathoms. Temp. 46°’2 E. Mud. Eive mutilated 
specimens, the disc varying in diameter from 2 '5 to 4 mm. 
Station 5. Lat. 60° 11' 45” K., and 60° 20' 15'' K., long. 8° 
15' AY. and 8° 8' W. 433-285 fathoms. Hard ground; stones. 
Temp. 43° -5 to 40° -8 E. 
The calices and arm-bases of two individuals were obtained here. 
The larger one, with a disc 6 '5 mm. in diameter, does not reach the 
size of some of the specimens dredged by the “Blake” off the coast 
of Kew England. 
Attached to the disc of each was an example of von GralEs new
