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



Cephalic segment small, cordate ; antennae 1 7-jointed, short ; labium smooth, sutures di- 

 stinct; mandibular tooth small; dental plates large, somewhat quadrate, with the an- 

 terior margin straight, punctured, and the posterior angle elongated ; labial palpi with 

 a small tubercle near the distal interior angle of the second joint ; third joint spoon- 

 shaped, with the superior margin ciliated and the apex toothed. Basilar joint of the 

 posterior pair of legs convex, with the external margin rounded ; internal margin irre- 

 gular, with seven minute black spines, four of which are ranged in a line that extends 

 diagonally upwards ; articular spine minute ; internal surface rounded, with seven or 

 eight small black spines, arranged in three oblique series, two, three or four in each 

 series, the middle series extending backwards and upwards to the upper surface of the 

 joint ; inferior surface rounded, with six minute spines, arranged in two transverse 

 series ; inferior surface of the distal extremity of the terminal joint of all the legs with 

 a minute spine sunk in a little foveola. Lateral anal appendages short, thick, with the 

 process short and acute. Preanal scale four-sided, a little elongated and narrowed, 

 with the posterior margin rounded. 



The specimen in the British Museum from which I have taken this descrip- 

 tion is that described by Leach. It has been stuffed with cotton wool, while 

 in the recent state, and hence has retained its uriginal colours ; but it is ex- 

 tended greatly beyond its original size, and now measures about thirteen inches 

 in length. Its natural length seems to have been from ten to eleven inches. 

 There is no notice attached to it of the country from whence it was derived, but 

 there is a specimen of the same species in the Museum of the United Service, 

 that was sent by Sir Robert Kerr Porter from Venezuela in South America.
