Conchoecia acuticosta, Muller, 1906a, p. 87, pi. XXX, figs. 18-21 ; id. 1912, p. 78. 



, Stations 50, 64, 65, 67, 68 (Atlantic). Surface. Stations 85 and 87 (North of 

 New Zealand). Two to thirty metres. 



The Terra Nova records extend our knowledge of the distribution of this species 

 northwards to 29° N. in the Atlantic, and eastwards to the Pacific Ocean, from which 

 ocean it has not been previously reported. Dr. G. W. Muller has recorded it from the 

 Indian Ocean (91° E.) and from the Atlantic (4° N. to 35° S.). 



The sculpture is very variable, even in specimens from the same haul, and it is 

 sometimes almost invisible.
