GONIODOEIS NODOSA. 



The spawn forms a thick narrow belt, curved into an imperfect circle, and is generally 

 of a rosy hue. The eggs are small and numerous, nearly filling the gelatinous envelope. 

 Sometimes the coil takes a second irregular turn, having the appearance of two masses 

 united, as represented in the drawing.
