604 NOTES AND KXHIBITS. 



reverted to the original name in his "Census" [1889]: and the 

 evidence given above shows that K. Brown's change of name was 

 not warranted. The only obstacle in the way of following the 

 Baron's example seems to be, that the name, B. huifolia, has 

 l)een in undisputed use for more than Hfty years. 



Dr. Cleland exhibited specimens of Silette yaJlica var. qiiviupip- 

 vidnera Linn , an introduced weed, collected by him at Thirroul. 

 Mr. Cheel remarked that Benthara, in his Handbook of the 

 Britisli Flora (1858) recorded >S'. yallica Linn., as a native, and 

 quoted -S'. anylica Linn., as a synonym; adding that a " variety 

 with a dark spot on the petals, S. quiiiquevnliiera Linn., used to 

 be cultivated in flower-gardens," On the other liand, in the 

 third edition of the Student's Flora of the British Islands (1884:), 

 Sir J. D. Hooker recognised *S' yallica proper [flowers white or 

 pink], and var. S. quinqiiei'iulnera [petals white with a red spot], 

 and var. S. anylica [petals small, white, often jagged]. S. yallica 

 is the most common in Australia, and there are specimens of it 

 in the National Herbarium from numerous localities in New 

 South Wales. There are also specimens of var. quinqueimlnera. 

 with deep blood-red spots on the petals, from the following 

 localities. New South Wales: Boonoo Boonoo (J. L. Boorman; 

 November, 1904); Milton (R. H. Cambage: December, 1903); 

 Walcha Road (J. L. Boorman; December, 1912). — Victoria: 

 Lilydale (A H.S.Lucas; November, 1885). West Australia: 

 Karridale (R. Helms; October, 1898). 



Dr. H. Leighton Kesteven communicated the following Note. 

 — Examination of a series of skulls of Crocuddus porosus leads 

 me to record that, after a stage of development within the egg 

 at which the skull measures 25mm. in length, the two pterygoids 

 are united to form one median bone. This bone shows no trace 

 of a median suture, beyond that between its two naso-palatine 

 plates, which form the false palate and floor of the postnarial 

 canals behind the palatine bones. These skulls, therefore, pre- 

 sent the median parasplieiioid which, in the Journal of Anatomy 

 and Physiology (Vol. 1.), I postulated as the ancestral condition 

 of the reptilian pterygoids.
