obtained from a brown Coati, Nasuafusca, F. Cuv,, sent to the So- 

 ciety for post mortem examination by J. H. Lance, Esq. He stated 

 that this disease appeared to be rare among Quadrupeds, no previ- 

 ous instance of it having occurred to him among more than a hun- 

 dred individuals of various orders which he had dissected within 

 the last few years. 



A preparation was exhibited of a young common Macaque Monkey, 

 Macacus cynomol^us, La Cep , which was born at the Gardens on 

 the morning of the 25th January, but was dead when first noticed by 

 the keeper. It is the first instance that has occurred in the Society's 

 Menagerie of the birth of any Monkey of the Old Continent. 



The reading was concluded of a Paper entitled "A few Remarks 

 tending to illustrate the Natural History of two Annulose Genera, 

 namely Urania of Fabricius and Mygale of Walckenaer : by W. S. 

 MacLeay, Esq." 



Adverting in the first place to the doubts which prevail among 

 entomologists as to the true situation in nature of the genus Urania, 

 Mr. MacLeay proceeds to contribute towards the elucidation of the 

 problem, the history of one species which appears to him to be 

 possibly new. He characterizes it as 



Urania Fernandinje. Ur. alis nigris, anticis utrinque lineis 

 transversis auro-viridibus supra undecim, septimd, bifida, subtus 

 sex humeralibus latis, septimd bifidd, octavd longissimd trifidd, 

 reliquis apicalibus filiformibus ; posticis supra Jiascid fiaud ser~ 

 ratd et lineis ocio brevibus lateralibus transversis auro-viridibus.

Mr. MacLeay describes in great detail the perfect insect, and 

 points out, as far as printed descriptions and figures exhibit them, 

 (he having at present no access to cabinets,) the marks which di- 

 stinguish Ur. Sloanus, Godart, and Ur. Boisduvalii, Guer., from the 

 Cuban species. He conceives, however, from the many variations 

 that he discovers in it, that this insect may be merely a variety of 

 Ur. Sloanus, to which species Ur. Boisduvalii may also possibly 

 be referred as a small variety. 



The coast of Cuba, in every open sandy part of it, is girt imme- 

 diately above the coral reefs by a copse belt, close and nearly im- 

 penetrable, composed of almost one species of tree, the sea-side 

 Grape, Coccoloba uvifera, Linn. At the base of this belt grow van- 

 ous Euphorbiacea and Convolvuli ; and behind it the parched sand 

 supports many sea-side shrubs, including Palms, Ccesalpinice, Cacti, 

 &c, festooned with the flowers of Convolvuli, Echites, and other 

 climbing plants : the leaves are studded with small terrestrial shells ; 

 and large sea-shells, brought from their original element by the 

 singular Paguri which have usurped them, cluster round the short 

 stunted trunks. 



Among the shrubs of these sands the most interesting is Ompha- 

 lea triandra, the cob or hog-nut of Jamaica, a Euphorbiaceous 

 plant, but affording a most delicious and wholesome kernel: its 

 upper leaves are large, heart-shaped, and thick, having a leathery
