Ill this list there are 104 species, none of which have been found 

 beyond the limits of the province. An examination of the list will 

 show, however, that there are sufficient reasons for recognizing the 

 three subdivisions of the fauna, already given in the case of the Echin- 

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

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

 inces are almost wholly unknown, only one or two species having 

 been examined from each, while from the Panamian division a consid- 

 erable number are now made known, although there must be many 

 additional ones. The shallow water Gorgonians and corals have been 

 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 are peculiar to 

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