and 85 (off the Ivory Coast and the eastern end of Ghana) are certainly referable to 

 hup/en, then- cirri being slender and hardly at all expanded distally and the brachials 

 only very slightly flared, if at all. On the other hand, specimens from stations 147, 

 148, 153, and 163 (from stations to the north of Sierra Leone, 9 + N.) have expanded 

 cirri and more or less flared brachials, as in A. bifida moroccana. However, six speci- 

 mens from station 60 (off Liberia) and two from station 151 (due west of the northern 

 end of Sierra Leone) are intermediate, though tending towards the form of moroccana, 

 while three specimens from station 123 (off Gabon, 2 S., 9 E.) and one from station 

 116 (off Nigeria) are also intermediate, but tend towards A. hup/en. 



Only more material and better descriptions can settle the limits of these Atlantic 

 species of Antedon.

 914' N., long. 1531' W.) ; 120 meters; May 19, 1936 [Cadenat, 1938].

 eries Research Institute, A. R. Longhurst (20, B.M.). 



Doubtful localities. St. Vincent, Cape Verde Islands; shore [Vaney and John, 

 1939] (1, Royal Scottish Museum). 



Vanneau stations 37 and 46 (1924); Atlantic coast of Morocco [Mortensen, 1925]. 

 [NOTE BY A.M.C.] Both these are probably A. bifida moroccana like those from Goree, 

 Senegal. 



Geographical range. West Africa, from Sierra Leone to Gabon in the Gulf of 

 Guinea. 



Bathy metrical range. From the shore line down to 120 meters. 



Occurrence. Professor Greeff says that he found only a few specimens at Rolas, 

 on the shore cliffs at the lowest tide. 



History. It is probably to this species that the specimens collected by Prof. R. 

 Greeff at Rolas, on the equator in the Gulf of Guinea, and recorded as Antedon rosacea, 

 should be assigned. 



This form was described by Dr. Clemens Hartlaub in 1890 from a specimen he 

 found in the Hamburg Museum, from Wappou, on the Ivory Coast, collected by 

 Captain Hupfer. He described it in greater detail and figured it in the following year,
