more rays in the dorsal fin : and has also described two species of 

 oi Crenilabrus, Cuv., which he regards as new ; one of them has 

 three longitudinal rose-coloured bands on the white ground of the 

 body, others on the dorsal fin, a large blood-red spot on the ventral 

 fins, and D. 12 -f 10. A. 3 + 11; the other is banded likę the pre- 

 ceding, but is deeply rose-coloured on the back and pale yellow be- 

 low, has a black circle surrounding the base of the pectorcd fin, a 

 large red spot above the anus, the dorsal and caudal fins red, the anai 

 and ventrals yellow, the pectorals rose-coloured, and D. 12-|-9. 

 A. 3-1-11. He has also given a description of a Mitrana, Thunb., 

 of a very pale olive yellow towards the front and bro^^Ti to\vards the 

 tail, and marked on the back by white ocellated spots bordered with

In the šame department M. E. Lienard has contributed descrip- 

 tions, from recent specimens, of several Serrani described by Cuvier 

 and M.VfJenciennes in their ' Histoire Naturelle des Poissons' ; and 

 has also given a description of a Blennius, Linn., destitute of appen- 

 dages on the head. These fishes were observed in a voyage to the 

 Seychelle Islands, whence M. E. Lienard brought back with him to 

 the Mauritius a Chatodon of very varied colours, which M. A. Lienard 

 subseąuently described under the name of Chatodon diversicolor. 

 M. Desjardins has stated, in a note, that the Mango fish, Polynemus 

 longifilis, Cuv. & Vai., is not found, as had been announced, in the 

 Isle of France. And hie adds that he has prepared an alphabetical 

 index to the nine volumes of the ' Histoire Naturelle des Poissons ' 

 that had then reached the Mauritius. M. Magon has presented to 

 the Museum of the Society a fragment of a ship's coppered keel 

 pierced by the point of the upper jaw of a Histiophorus , Cuv., ^hich 

 still remains infixed in it. 



M. Desjardins has contributed the only notices relative to the Mol- 

 lusca, which have consisted of short descriptions of three species be- 

 longing to the island : an Octopus, Oct. arenarius, Desj., found in 

 the shell of a Dolium ; a Pupa, of a red and yellow colour ; and a 

 small species of Helicina. He has also ascertained the existence at 

 the Mauritius of the Tornatella flammea, Auct. 



To the šame active member the Mauritius Natūrai History Society 

 is indebted for the only entomological communication made to it in 

 the fifth year of its existence : it is a detailed description of a large 

 species of lulus brought from the Seychelles, and characterized as 

 the lulus Seychellarum, Desj. 



Specimens were exhibited of various Fishes, forming part of a col- 

 lection from Mauritius, presented to the Society by M. Julien Des- 

 jardins, and forwarded by him at the šame time with the " Rapports 

 de la Sociėtė d'Histoire Naturelle de l'Ile Maurice." These were 

 severally brought under the notice of the Meeting by Mr. Bennett, 

 who called particular attention to the follo^v^ng, which he regarded 

 as hitherto undescribed.
