Two species of Ancistrona have been described. We have several 

 examples of .4. yigas, P. (Fulmar us glacialis) in our collection, and 

 have seen the types of A. procellariae (British Museum collection), 

 but the latter were at the time unmounted. We think Dr. Peringuey's 

 two specimens agree best with procellariae. But it is not certain 

 that there are two really distinct species.

This, Piaget thinks, is only a variety of C. candatum, G. We 

 have had no opportunity of comparing the genitalia of the two 



forms.
