We have not overlooked Mjoberg's clearly defined" Pectinopygus " 

 (1910) which he proposes as a new genus for this species. But it is 

 our present opinion that the two main characters of this division, 

 viz. the peculiar 3rd joint of the antennae $ and the uniquely 

 "pectinated" genitalia $ are of specific not generic value. The 

 genitalia $ should be used for systematic purposes with great 

 caution, and only when a group of species show a well-marked 

 type of apparatus. Otherwise our classification will be loaded with 

 monotypic genera. 



The group embracing the Lipeuri of Sula we imagine will 

 ultimately prove to be a fairly compact one whether worthy of 

 generic rank or not future research must decide. We have seen 

 only L. pullatus, N. (Sula bassana, S. capensis) and L. potens (Sula 

 piscatrix). We do not think that a fair classification will separate 

 these species, but their respective genitalia $ are of entirely 

 different types. Interestingly enough the 5 $ genitalia of these 

 species offer points of resemblance. The organization of the ? as 

 a whole seems more stable and primitive.
