Antkomastus agassizii (Verrill) 



Anthomastus agassizii^ Verrill, 1922:40 

 Anthomastus agassizii ^ Deichmann, 1936:54 



This species is similar in appearance to A. grandif torus . 

 In his original description Verrill differentiated the two species 

 on the basis of differences in the size of the polyps (smaller in 

 agassizii ) and in the size and shape of the spicules (longer and 

 more spinulose spindles and more strongly warted stellate forms) . 

 Deichmann further defined the species to include only attached 

 colonies (stalk ending in adhesive disk rather than a multilobed 

 anchor) in which the autozooids are scattered across the entire 

 disc and not confined to the margin. A. agassizii is also bright 

 red in color and its bathymetric and geographic distribution 

 overlap that of A. grandif torus . It has been reported from George's 

 Bank to the Lesser Antilles at depths of 200 to 10 30 fm. 



In the historical survey this species was found from Corsair 

 Canyon to Hudson Canyon between the depths of 750 to 1900 m. 

 Highest concentrations were observed in the axes of Oceanographer 

 and Heezen Canyons. In the field study only several individuals 

 of A. agassizii were found. They occurred between 1057 to 1326 m 

 in Oceanographer Canyon.
