PLATE 58 



Fig. 1. Bossea pachyclaJa. Three somewhat fragmentary speci- 

 mens. Unfortunately it was not realized with what ease 

 or to what degree the corallines of this district would 

 disintegrate after drying, and in the several years elaps- 

 ing between the collection of material and the prepara- 

 tion of the illustrations, some, and notabi}- the present, 

 for the most part broke up into individual segments. 

 However the shape of segments in the lower axes is 

 quite evident, and in particular in the right-hand speci- 

 men, the shape of the upper segments. The conceptacles, 

 abundant in the material, may also be seen in the right- 

 hand specimen and in other scattered places. I. Cerros.
