Mr. Newport on the Class Myriapoda, Order Chilopoda. 403 



tened, with the superior surface subconvex, and the external margin subacute ; inter- 

 nal margin and surface with a multitude of minute black spinulae, from thirty to forty 

 in number, distributed both over the internal surface and margin, and on the internal 

 superior surface ; internal angular process large, with the apex multifid. Inferior sur- 

 face rounded, with from fifteen to twenty very minute points distributed in little irre- 

 gular transverse clusters of three or four in each cluster, usually arranged in a trans- 

 verse direction ; tibial joint shorter than the femoral, rounded. Lateral anal appen- 

 dages smooth, but not polished, with the apex produced and multifid, and a minute 

 tooth at the external posterior border ; preanal scale flattened, small and elongate, 

 rounded posteriorly, with the margin straight. 



The chief characteristic marks of this species are the labial teeth, and the 

 number and great irregularity of the tubercles on the posterior pair of legs. 

 These are too irregular to afford a good description. The specimen from 

 which the above description was taken has Dr. Leach's autograph specific name 

 attached to it.

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



Cephalic segment cordate, with two longitudinal, slightly elevated cristae ; basilar segment 

 with two oblique ones. Mandibular tooth moderate ; labium smooth, with very mi- 

 nute punctures ; dental plates strong, subquadrate ; teeth six, the two external ones on 

 each side strong, acute, triangular, with the internal one on each side acute, dilated, 

 subquadrate at its anterior margin ; dorsal surface of the body with two minute ele- 

 vated cristae, extending from the head to the terminal segment ; basilar segment of the 

 posterior pair of legs elongated, with the superior surface and external margin rounded ; 

 internal surface and margin with at least fifteen small spines, three of which are 

 arranged in a longitudinal series on the internal margin, and the others in three ob- 

 lique lines on the internal surface ; inferior surface convex, with from twelve to four- 

 teen spines arranged in three alternating longitudinal series. Lateral anal appendages 

 smooth, with the apex multifid, and three minute tubercles on the posterior margin. 

 Preanal scale narrow, elongated, with posterior margin straight. 



I have much pleasure in naming this fine species in honour of J. E. Gray,
