Our specimen does not exactly correspond to the published figures 

 as the ovicell is distinctly separated 

 from the large avicularia and bears 

 an elliptical frontal area. Most of 

 our specimens were dead and we / \ f \ 



have not been able to verify the / \ I V 



number of spines. They incrust A B 



shells and algae. The other char- 

 acters are quite identical. In con- „ . n „ , ., „. ,
