Mr. Newport on the Class Myriapoda, Order Chilopoda. 399 



trifid. Preanal scale elongate quadrate, with a longitudinal depression, posteriorly 

 rounded. 



This specimen was brought by Capt. Sir E. Belcher, R.N., of the Sulphur, 

 and is believed to be from China. I have a strong suspicion however that 

 this is a mistake, and that it is a South American species.

Cephalic segment subovate, elongated, with the posterior margin nearly straight; basilar 

 segment large ; dental plates elongated, quadrate, with the anterior margin straight, or 

 slightly excavated ; the inferior surface with a deep triangular excavation bounded by 

 the internal and external tooth on each plate ; teeth eight, the three internal ones on 

 each plate obtuse, subapproximated ; the external one acute, elongated, and distinct 

 from the others ; labium smooth, separated from the dental plates by a distinct border.

 face flattened, with the external margin subacute ; internal margin with from eight to
