with on Paspalum scrohiculatum. U. EMaDBNSis, Berk., in 

 Queensland is found on the stipules of Polygonum near 

 Brisbane. U. leucoderma, Berk. — A species met with 

 both in Borneo and St. Domingo, has been found on Sedges 

 at Bundaberg-, Queensland. 



In concluding this review of the Queensland Bhght Fungi, 

 it would seem that some explanations or remarks become 

 necessary. It may have occurred to many that a genus like 

 Peronospora must be represented by more than a single 

 species in a colony with such an extensive blight flora as 

 Queensland, and such is most probably the case ; but these 

 kinds are only brought to our knowledge when their ravages 

 are observed upon plants under cultivation, and may in 

 many instances escape the cultivator's observation. It is 

 also quite within belief that a large number of species of 

 Peronospora and similar fungi are to be found abundant upon 

 the indigenous vegetation, and that they will from time to 

 time come from thence and fasten upon cultivated plants, 

 especially when such are allied to those they may be living 

 upon in a wild state. As we find in the animal kingdom the 

 wild man preferring sheep to kangaroo, the flying-fox peaches 

 to quandong, the grassho})per the more succulent vegetation 

 of our gardens to the dry herbage of the plains, so in like 

 manner we shall doubtless find from time to time blight- 

 fungi, at present unknown, will come from the indigenous 

 plants to exotic ones which may be more congenial to their 

 development. 



7.— PRELIMINARY NOTE ON THE VESICULA 

 SEMINALIS AND THE SPERMATOPHORES OF 

 CALLORHYNCHUS ANTARCTICUS.

The great size of the vesiculse seminalis of Callorhynchus 

 and the remarkable mode of aggregation of the contained 

 sperms must have struck everyone who has dissected this 

 extraordinai-y fish. I made some notes and drawings on the 

 subject about eleven years ago, but owing to the pressure of 

 other work laid the matter aside until now. The only pub- 

 lished paper dealing with the question which has come under
