Obs. Mr. Salisbury has united such of the New Hol- 

 land Protese as he had seen, into one genus, which he calls 

 Atylus ; a name meant to express the want of those bodies 

 that usually surround the ovarium, in this order, and which 

 he chooses to term colli : but as I conceive they are certainly 

 secreting organs, the name on this ground would be ex- 

 ceptionable : my chief reason however for not adopting it, 

 either for the present or the following genus, is, that the 

 whole of his essential character does not apply to either of 

 them. In his secondary character he has also considered 

 them as monoicous, a mistake into which he has probably 

 been led, not only from the striking similarity between the 

 strobili of Petrojjkila and Leucadendron, but also from the 

 style of the former remaining for some time unwithered 

 after the calyx has fallen off. In one species he has even 

 described the relative situation of the sexes ; regarding the 

 terminating amentum of P. pidchella as female, and the 

 lesser ones, which frequently though not always surround
