November 12, 1833. 

 Richard Owen, Esq., in the Chair, 



A letter was read, addressed to the Secretary by M. Julien Des- 

 jardins, Corr. Memb. Z. S., and dated Mauritius, June20, 1833. It 

 was accompanied by an " Extrait du Troisiėme Rapport sur les 

 TravauK de la Sociėte d'Histoire Naturelle de l'Ile Maurice," of 

 which Society M. J, Desjardins is the Secretary. This extract, 

 containing an account of the Zoological Proceedings of the Mau- 

 ritius Natūrai History Society, was read. 



In Ornithology only one paper has been read. It is a description, 

 by M. J. Desjardins, of the Greenshanh, Totanus Glottis, Cuv., taken 

 frora a specimen killed in Mauritius : the bird not being knovvn to 

 have previously occurred in the island. 



In Ichthyology the contributions have been numerous. M. Lie- 

 nard, sen., has described a new species of Grammistes, Cuv., distin- 

 guishable from the two previously koown by its compressed form, 

 on which account it has been designated Gramm. compressus : its 

 first dorsal fin has nine rays. He has also described a new species 

 of Cirrhites, Cuv., remarkable for a vertical septum formed in the 

 middle of its palate by a prolongation of ihe lining membrane of the 

 mouth: and an Aphareus, Cuv., which to some differences in the 

 number of the rays from Aph. ccerulescens, Cuv., adds othersin co- 

 louring, and particularly a yellow spot on the forehead, and an- 

 other near the angle of the prcsoperculum. He has given a par- 

 ticular account of Epibulus Insidiator, Cuv., and of its anatomy ; 

 and has noticed a fish, vvhich he regards as a variety of this species, 

 distinguished principally by its colou.r being pale yellow instead of 

 reddish green. He has also described Trichiurus lepturus, Linn. ; 

 and Žandus comutus, Cuv., adverting, as regards the latter, to some 

 particulars of the anatomy of this scaleless Chcetodon. M. E. Ližnard 

 has described two nevr species of Holacanthus, La Cėp., one of 

 which is marked v^ith numerous transverse bands, of which the an- 

 terior are interrupted ; the other having also numerous bands simi- 

 larly directed, but curved. M. J. Liėnard has given a detailed de- 

 scription of a fish, which he regards as constituting a new subgenus 

 betvveen Anampses, Cuv., and Odax, Ej.: it has six incisor teeth, 

 and these, instead of being directed outvvards likę the two incisors 

 of Anampses, are curved inwards. And lastly, M. J. Desjardins has 

 described two new species of Chcetodon, Cuv. : one of them, Chcet. 

 Jėstivus, has a large eye-like spot on the soft rays of the dorsal fin, 

 and a black spot on those of the anai ; its form is orbicular, and the 

 spinous rays of its dorsal fin are tvvelve: the other, Chcet. chrysu- 

 rus, is of a rather elongated form, and has thirteen spinous rays in 

 its dorsal fin ; its principai markings are eight transverse bands, 

 angular in the middle, succeeded by a white zone, vvhich is followed 

 by a region of orange yellow occupying the soft part of the dorsal 

 and %nal fins and the \vhole of the tail, and becoming paler at its 

 hinder part.
