M. J, Desjardins has also described a ncvv species cf the Crusla- 

 ceous genus Ranina, Desm., to which he has given the name oi Ran. 

 cristata. 



In Entomology M. W. Bojer has described a new species of the 

 Priomdous genus Dorysthenes, Vig. ; and M. J. Desjardins has given 

 an account of three nevv species of LibeUula, Linn., under the re- 

 spective names of Lih. limbatu, Lib. semihyalina, and Lib. bimacu- 

 lata, ali being indigenous to Mauritius. 



The Secretary called the attention of the Society to severaI ani- 

 mals vvhich had recen.ly been added to the Menagerie. They in- 

 cluded an urdne Opossum, Dnsi/urus ursinus, GeofF., an animal 

 known to the colonists of Van Diemcn's Land by the appellation of 

 the Native Devil; a Secretary Vulture, Gypogeraniis serpentarius, III., 

 presented to the Society by Lieutenant-General Sir Lowry Cole; 

 and tvio crotuned Cranes, presented by the šame distinguished officer, 

 on his return from the government of the Cape of Good Hope. 



Referring more particularly to the latter, he brought under the 

 notice of the Meeting specimens from the Society's Museum of 

 croivned Cranes from Northern and from Southern Africa, with the 

 view of illustrating the characters \vhich distinguish as species the 

 birds from these severaI localities. Tlicir specific distinction, he 

 stated, on the authority of Professor Lichtenstein, had been pointed 

 out, nearly thirty years since, by the Professor's father, who gavę 

 to the Cape bird the name of Grns Regulorum : this distinction 

 has, however, not been generally known among ornithologists, al- 

 though to those connected with the Society it has for some time 

 been familiar, from observation both of numerous si<ins and of living 

 individuals. In the bird of Nortli Africa, for which the specific 

 name of pavoninus will be rtlained, tlie wattle is small, and there 

 is much red occupying the lovver two tliirds of the naked cheeks : in 

 that of South Africa the wattle is large, and the cheeks are white, 

 except in a small space at thtir upper part ; the neck also is of a 

 much paier slate colour than that of the North African species. 

 He added that the latter characters had been observed to be per* 

 manent in an individual presented to the Society, in April 1829, from 

 the collection of the late Marchioness of Londonderry, and which 

 is still living at the Gardens : theyexist also in both the individuals 

 presented by Sir Lowry Cole. 



The t\vo species may be thus distinguished : 



Genus Anibropoides, Vieill. 



* OccipHe cristato, cristd erectJ, ęff'usn, e plumis setaceis constante. 



Anthropoides pavoninus, Vieill. Anth. genis nudis, supemi 



albis infern"" late roseis ; paleari minimo ; gutturis plumis elon- 



satis nisrescentibus. 

 Ardea pavonina, Lmn. et Aud. 

 Hab. in Africa Septentrionali et Occidentali. 

 Anthropoi'des Regulorum. Anth. genis nudis, albis superne 



roseis; paleari magno ; gutturis plumis elongntis pendulis coeru- 



lescenti-cinereis.
