M. Li^nard, the elder, has, in the course of the year, described 

 many FisAes, including a new species of Plectropoma, allied to the 

 Plectr. melanoleuca, Cuv. & Vai., which is of a uniform brown co- 

 lour, with all its fins of a still deeper bro\vn, except the pectoral 

 which are orange ; on this latter character his specific name is 

 founded : a Holacanthus, La Cep., from Batavia, remarkable on ac- 

 count of the numerous sinuous silvery lines which occupy prmcipally 

 the middle of the body ; and ha\T[ng also on its face two yellovv and 

 two black bands, one of which is ocular : a Cheilinus, Cuv. : an 

 Echenąis, Linn., fumished, on its suctorial disc, with twenty-five 

 pairs of platės : and a Muraną, Thunb., the body of which is of aa 

 ebony black, and the dorsal fin yellow ; the trivial name being in- 

 dicative of the latter peculiarity. He has also given some account of 

 a collection of Fishes obtained from the western coast of Madagsis- 

 car, and comprising thirteen species, several of •vvhich he regards as 

 new. M. Desjardins has described as the blue-facedTetrodon, a species 

 remarkable for two large blue spots on each side of its face, and 

 having the fin rays as follows; D. 15. A. 12. P. 14. C. 14.: it in- 

 habits the seas adjacent to the Isle of France. 



In entomology the only communication made to the Mauritius 

 Society was by M. Goudot, and related to the Insect described by 

 Mr. Bennett at the Meeting of the Zoological Society on January 22, 

 1833, (Proceedings, Part i., p. 12,) under the name of Aphrophora 

 Goudoti. The communication made to the Zoological Society, of 

 \vhich a' full abstract is given at the page ąuoted, was apparently 

 identical with that read before the Mauritius Society. 



The remaining zoological communication related to the Intestinal 

 JVorms, and was made by the Secretary. It gavę some account of 

 t]x& Distoma hepaticum, Cuv., as found in the stomach of a co\v; and 

 of the Cysticercus Cellulosce, Brems., existing in innumerable quan- 

 tities over almost the whole of the head, trunk, and extremities of

In the year of which the present Report gives an account, M. 

 Desjardins has communicated to the Natūrai History Society of the 

 Mauritius, a list of several species of Birds that are occasional visi- 

 tors of that island ; and has also referred particularly to the Coturnix 

 Sinensis, Cuv., and the Nectarinia Borbonica, 111., as stationary in 

 the Mauritius. 



M. E. Liėnard has brought from the Seychelles a species of Gecko 

 of considerable size ; which he has described in a communication 

 made to the Society : and M. E. Lienard has placed on record the 

 existence in the adjacent seas of the Sphargis coriaceus, Merr. 



M. Lienard, the elder, has again made numerous contributions to 

 ichthyology. He has given a detailed description of the Squalus 

 Vulpes, Linn. : has described as new a Trichiurus, Linn., which he 

 had formerly regarded as the Trich. lepturiis, Ej., but which has the 

 cye much largėr, more numerous strice on the suboperculum, and a few
