the septa of the peripheral stomach. These reddish stripes extend about half-way from the 

 bell-margin toward the center of the exumbrella and are due to highly refractive, rosin- 

 colored pigment granules within the epithelial cells of the disk. The male gonads are 

 generally pink, while the ovaries are yellowish or ashy-gray. The radial muscle-strands of 

 the subumbrella are of a glistening white and the entodermal cores of the tentacles are pink. 

 The mouth-arms are pink or yellow and always sprinkled over with red-colored pigment spots. 

 The marginal sense-organs contain each a mass of glistening white concretions, but no ocelli. 

 This species extends from the southern coast of New England to the tropics. In August 

 it is abundant in Tampa Bay, Florida. It has been taken by Bickmore at the Bermudas, 

 and by Drayton between the Bermudas and the Azores. "A well-marked southern variety"
