B-12 



range in color from a light tan to dark red. This species has 

 been reported from most northern seas and is probably circiom- 

 boreal. In the western Atlantic the southern-most record is 

 for the Baltimore Canyon. It usually occurs at depths of 100- 

 300 fm. 



In the historical survey this species was found in the axis 

 of Norfolk Canyon between 450 and 600 m, and in the axis of 

 Oceanographer Canyon between 700 and 1072 m. In the field study 

 large colonies of T. avhorea were observed between 400 and 500 

 m. in the axis of Baltimore Canyon. This species was also found 

 in both Lydonia and Oceanographer Canyon between the depths of 

 300 to 900 m.

Anthothela gvandiflora is a scleraxonian gorgonian which 



normally forms flat encrusting colonies. It can be found growing 



on stones, shells and, quite frequently, on the dead axes of other 



gorgonians. Occasionally developing from these encrustations are 



small sparsely branched upright colonies. In the latter case the 



central core of the branches is composed of densely packed spicules 



and acts as an axial support for the colonies, as in Paragorgia 



arborea. In encrusting colonies the large cylindrical calyces 



(3-6 mm high) are usually crowded together, but in branched 



colonies they can be 0.5 to 2.0 cm apart. The margin of the
