marking of Paradoxurus : the skin has the odour of civet. From 

 the genus Viverra it is distinguished by the shape of its skull, the 

 cerebral cavity being in it much larger, the space between the eyes 

 broader, and the nose much broader and shorter. The species was 

 characterized in the following terms : 



Pagum A LARVATA. Pag.grtseu ; fascia albafrontcdi transversa, 

 alteraque longitudinali per Jrontem ad nasum ducta ; cauda 

 apice nigrescenti. 



Gulo larvatus. Ham. Smith in Griff". Transl. Cuv. Regn. An. ii. 

 p. 281, c. fig. 



Viverra larvata. Gray, Spic. Zool. p. 9. 



The third genus described was founded on a glirine quadruped, 

 nearly allied to the Bamboo-Rat {Mus Sumatreiisis, Raffl. ?), with 

 which Mr. Gray associated it under the following characters. 



/•Rhizomys. 

 Denies primores -f maximi, elongati, triangidares , acutati: mo- 

 lares 4 4 radicati, subcylindrici, coronis transversim subparal- 

 lelim porcatis ; superiores interne lobati. Caput magnum. Oculi 

 parvi aperti. Auriculce nudce conspicuce. Corpus crassum sub- 

 cylindricum. Pedes breves validi, digitis 5 — 5. Cauda mediocris, 

 crassa, nuda. 

 In teeth and general appearance this genus is most nearly allied 

 to Spalax, from which it differs in its tail of moderate length, its 

 exposed eyes and ears, and the more complex character of its 

 molar teeth. The species of Rhizomys live moreover upon, and 

 not under, the ground, being found about Bamboo-hedges, on the 

 roots of which they principally subsist. The following were stated 

 to be the distinctive characters of the two species known. 

 Rhizomys Sinensis. Rhiz. pallide cinerascens unicolor. 

 Hab. in China. D. Reeves. 



Rhizomys Sumatrensis. Pallide Juscus, pilis raris albidis in- 



terspersis ; corporis lateribus pedibusque saturatioribus ; genis 



pallidioribus, occipite nigrescenti lined longitudinali alba, pec- 



tore albido. 



Mus Sumatrensis, Raffles, Linn. Trans, xiii. 258 ? Temminck, 



Mus. Leyd. 

 Spalax Javanus, Cuv. Regne Anim., ed, 2., i. 211. 

 Hab. in Sumatra, Raffles? Temminck ; Java, Cuvier. 

 The latter species seems to have been first observed by Colonel 

 Farquhar, in whose collection of drawings, preserved in the Museum 

 of the Asiatic Society, a representation of it is found. Of the former 

 we owe the discovery to Mr. Reeves.

preparation of iodic acid. by ARTHUR CONNELL, A.M. 



THE methods which have been hitherto followed for the formation 

 of iodic acid, may be reduced, Mr. Connell remarks, to three : 

 first, the action of alkaline solutions, giving rise to the formation of 



2 H 2 a hydrio-
