 oderms (p. 33 7). But the three subdivisions are not equally well 

 known. The Actinians of the Mexican and Equadorian sub-prov-

 pretty fully collected in both the Mexican and Panamian regions, but 

 from the Equadorian we have only the small collection obtained by 

 Mr. Bradley at Zorritos. In the present state of our knowledge some 

 of the species found in each of the three sub-provinces aie peculiar to 

 it, while many extend also to one of the other, and a considerable
