504 NOTES AND EXHIBITS. 



anew, but I placed after his observation B. Jloribunda ab-eady 

 into full specific rank in the Second Census of Australian Plants 

 (p 18). Sprengel's diagnosis of this plant published in 1827 is 

 very brief and applied as well to some forms of B. 'pinnata as to 

 B. Jloribunda, the main distinctions not being given, namely, the 

 much reduced size of four of the stamens and the short style with 

 much dilated stigma. It was only recently that my attention 

 from Prof. XJrban's indications was directed to this subject, when 

 Miss Georgina King, the zealous amateur lady naturalist of your 

 colony, forwarded splendid specimens of B. floribunda to me from 

 the Hawkesbury River, her plant proving to Ije the genuine 

 one of Sieber. Unlike B. pinnata, which abounds in many places 

 of four of the Australian colonies, the B. Jloribunda seems 

 restricted to N.S. Wales, and I have it even from your territory 

 only from Mrs. Capt. Rowan, the celebrated flower paintress, 

 who sent it mixed with B, pinnata from the vicinity of Botany 

 Bay, irrespective of the sendings of Miss King, and I have 

 Sieberian specimens in the collections of Drs. Steetz and Bonder. 

 Thus it remains to be ascertained what are the geographic areas 

 of B. Jloribunda, and this might largely be settled at once ])y a 

 re-examination of Sydney herbaria. The specific validity of B. 

 Jloribunda will likely be affirmed still further by a search for the 

 ripe fruit, which as yet is to me entirely unknown, good charac- 

 teristics being derived from pericarp and seeds of many Boronias. 



Mr. Ogilby contributed a note pointing out that there are two 

 genera of recent rough-backed Herrings in our waters, both of 

 them generically distinct from Dijdoniystus, which may be In'iefly 

 characterised as follows :■ — • 



a. Maxillaries narrow, 3^ to 4 in the diameter of the eye. 

 Jaws, palatines, and tongue toothed. Eight branchiostegals. 

 Dorsal inserted well in front of the middle of the body; anal 

 moderate, its base as long as its distance from the caudal; 

 ventrals inserted beneath the anterior third of the dorsal. 

 Scales with smooth posterior border ... 



Polamei-Iosa.
