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



the labium is flattened, with the dental plates very large, and armed with six powerful, 

 triangular, acute, deeply sulcated, black teeth, the internal one on each side bifid : the 

 body and legs are olivaceous, with obscure fasciae ; posterior pair castaneous, elon- 

 gated, with a raised longitudinal line on the upper surface of the basilar joint, with the 

 margins acute, the internal one with five sharp spines in two alternating series. In- 

 ferior surface with six spines in two longitudinal series, three in each series. Lateral 

 anal appendages elongated and acute, with two spinulae on the external surface. Pre- 

 anal scale subtrigonal, with the posterior border emarginated.

The specimens in the Linnean Society's collection measure nearly six inches in length and 

 are of a dark blue colour : the antennee are fuscous and pubescent at the apex ; the 

 labium smooth and the dental plate deeply punctured : the legs are yellowish green, 

 with the claws black ; the spines on the internal margin of the posterior pair are very 

 strong and acute, and are arranged in two irregular series, the second and fourth spines 

 being on the internal surface ; the inferior surface of the joint is also armed with six 

 spines, three of which are arranged in a longitudinal series on the external border, and 

 two in a series on the internal, with the remaining spine, the anterior one of the in- 

 ternal series on the internal surface, near the basal articulation of the limb. Lateral 

 appendages punctured, with the apex bifid, and two spines on the external inferior 

 surface and five or six very minute ones on the superior margin, Preanal scale cor- 

 date, deeply emarginated. 



6. Heter. sulcicomis, ochracea, antennis elongatis pilis minutis strigosis, dentibus 6 mag-

 basali spinis 6 nigris in margine interiore superiore 6que in superficie inferiore. — Long.
