A paper was read, entitled " Memoire sur une Nouvelle Esp^ce 

 de Poisson du Genre Histiophore, de la Mer Rouge : par M. E. Riip- 

 pell, M.D., Memb. Ext. Z. S." It was accompanied by a drawing 

 of the fish described in it. 



MM. Cuvier and Valenciennes have described, in their ' Histoire 

 NatureUe des Poissons,' three species of Sword-fishes of the genus 

 Histiophorus ; from all of which Dr. Riippell regards his fish as di- 

 stinct, although it apparently approaches most nearly to Hist. Ame- 

 ricanus : it should seem that its occurrence at Djetta, on the coast 

 of Arabia, was only accidental, as the Arab fishermen knew no name 

 for it. The most striking peculiarity of the new sjjecies is the uni- 

 formity of the colour of its dorsal fin : in all those which were pre- 

 viously known the first dorsal fin is varied with spots ; in the one 

 obtained by Dr. Riippell, the first dorsal fin is black throughout and 

 destitute of spots, on which account its discoverer proposes for it 

 the name of 



Histiophorus immaculatus. Hist, pinnis pectoralibus mediocri- 

 bus ; dorsali nigrd, immaculatd. 

 D.47, 0-f7. A.IO, 0-h7. C.5 + 17 + 5. P. 1 + 19. V. 3. 



Pinnae pectorales quam in Hist. Indico, Cuv. & Val., multo mi- 

 nores : utpote quae in illo -J- vel -^ corporis longitudine sequant, in 

 Hist, immaculato -^ tantum. In Hist, pulchello praeoperculi angu- 

 lus spina munitus : in Hist, immaculato aliisque inermis. Hist. 

 Americani pinna dorsalis cinereo-argentea, maculis brunneis rotun- 

 datis ornata. 



Dr. Riippell describes the fish in considerable detail. He has not, 

 however, examined it anatomiccdly, on account of his possessing 

 only one specimen, which he had deposited in the Frankfort Mu- 

 seum. 



The following notes by Sir Robert Heron, Bart., were read. 



" In many books that I have seen some errors are made in the 

 history of the Kangaroos, which my long possession of those animals 

 enables me to correct. 



"The great Kangaroo does not make use of liis tail in leaping. 

 He uses it in walking, and still more in standing. When excited.
