Mr. Newport on the Class Myriapoda, Order Chilopoda. 411 



Genus 9. Branchiostoma*, Newp. 



Antenna pedesqne elongati. Dentes triangulares acuti, mandibularis maximus. Spiracula 

 circularia, membrana branchiformi corrugata intus vestita. Pedes postremi graciles ; 

 spinis minutis, articular! plerumque obsolete. 



1 . Branch, lithobioides, virescens fasciis saturatioribus transversis, capite segmento postremo 



superficie ventrali femoribusque aurantiacis, articulis tibialibus tarsalibusque viridibus, 

 dentibus 6 e quibus 2 interiores cujusvis laminae coaliti, pedibus postremis cylindricis 

 spinulis 6 in margine superiore interne. — Long. unc. If. 

 Hub. In China, (r. in Mus. D. Hope.) 



In its general appearance this species resembles a Lilhobius. The mandibles and mandi- 

 bular tooth are large, and the labium is smooth, with a few scattered obsolete punctures. 

 The dental plates are distinct, quadrate, and the teeth six, black and acute, the two 

 internal ones on each plate united. All the legs are elongated ; the posterior pair are 

 slender, cylindrical, and armed on the internal superior surface of the femoral joint with 

 six spinulae, but there is no articular spine or process. The inferior surface has six 

 acute black spinulae, arranged in two longitudinal series, three in each series ; those in 

 the internal one are slightly approximated. The lateral appendages are elongated, with 

 the apex bifid. Preanal scale subquadrate, narrowed posteriorly, with the border emar- 

 ginated. 



2. Branch, longipes, fusca, mandibulis labio appendicibusque analibus lateralibus auranti- 



acis, dentibus 4 triangularibus lobulatis acutis nigris, pedibus postremis elongatis ; 

 articulo basali gracili pauliim complanato spinuhs 3 in margine superiore interno e 

 quibus 2 anteriores subapproximatae 7que in superficie inferiore. — Long. unc. If. 

 Hab. ? {v. in Mus. Brit.) 



The cephalic segment is somewhat flattened ; antennae 19-jointed ; teeth two on each plate, 

 lobulated, triangular, and very acute ; posterior pair of legs elongated, with the femoral 

 longer than the tibial joint, slender, and with its upper surface flattened, with three spi- 

 nulae on the internal margin, the two anterior of which are subapproximated, and near 

 the base of the joint ; inferior surface with seven black spinulae, arranged in two lon- 

 gitudinal series, four in the outer and three in the inner one. Lateral anal appendages 

 orange-coloured, punctured, elongated, with the apex bifid, and a single spinula on the 

 external surface. Preanal scale subcordate, with the posterior margin straight.
