near the margins, especially the columellar, mixed with a few ex- 

 ceedingly faint rainute spots lighter coloured than the ground. Base 

 nearly white, rather flat. Aperture narrovv : columella somewhat 

 gibbous at the middle part : teeth, likę the base, nearly w-hite, 

 even, not minute, extending half across the lip, on which there are 

 about nineteen, coloured at their edges of a reddish brown colour, 

 forming short lines ; teeth of the columella about eighteen, forming 

 an angular, slightly elevated, serrated, longitudinal ridge, more 

 prominent at the anterior extremity ; at the two extremities the 

 teeth extend a little outwards, and are there marked, as on the lip, 

 by reddish brovm little lines. At the anterior portion of the front 

 of the columella is a deep elongated groove, terminating outwardly 

 in a deep notch, between the end of the ridge and the beak, \vitli 

 three or four denticulations at its inner border, not extending through 

 it from the ridge. Extremities produced ; the beaks divergent ; the 

 outer anterior and posterior beaks larger and a little longer than 

 the inner. Intemal colour the šame as that of the base. Spire a 

 little prominent, with a depression around it superiorly and late- 

 rally. Dorsal line almost obsolete. 



The young has no markings on the teeth.

Doctor H. Beck, the leamed naturalist of Copenhagen, being at 

 this time in our capital, I have taken advantage of the circumstance 

 to date its period, by placing his name, now, to this new species of 

 Cyprcea. — J. S. G. 



There was read an "Extrait du Quatriėrae Rapport Annuel sur 

 les Travaux de la Societe d'Histoire Naturelle de ITle Maurice : par 

 M. Julien Desjardins." 



The Communications relative to the Mammalia read before the Na- 

 tūrai History Society of the Mauritius in the fourth year of its ex- 

 istence have comprised an account by the secretary, M. Julien 

 Desjardins, of a UTiale which he regards as the Physeter macroce- 

 phalus, Linn., that was cast ashore on an adjoining reef : and some 

 obsen'ations by the šame author on several of the Mammalia of the 

 island, and particularly on the hybemation of the Tenrec, Centenes 

 spinosus, 111. ; the lethargy of which animal takes place wlien the 

 thermometer is not lower than 20° Cent., and even when it marks 26"^. 



In ornithology M. Desjardins has also been the only contributor. 

 He has described, as ne%\% t\vo Birds belonging to the island, and has 

 proposed for thera the names of Ckaradrius Nesoffallicus and Scolo- 

 pax elegans.
