1901.] MYRIAPODA Or THE " SKEAT EXPEDITION." 519 



by At terns under the name nodvlosum. There are. however, some 

 important differences in the Malay specimens. 



Colour and shape as in Attems's description. The furrow 

 between the pro- and metazonites, which Attema describes as 

 " deutlich geperlt," shows no signs of any pearls or tubercles 

 even under a high power. Neither can I identify the " kleine 

 kurze Wiilste" on the pore-bearing segments, though there are 

 certain pores or marks in the chitinoua integument which may 

 possibly represent them. Neither can I find any sign of the 

 cross-shaped impression in the ventral plate. 



The sub-anal plate has two setiferous tubercles in the same 

 place as in Platyrhacidae and the two pairs of setiferous tubercles 

 at the sides of the anal valves. The copulatory foot is shown in 

 the figure. 



Stbokgylosojia (Obthomokpha) euscocollaris Pocock. ( Plate 

 XXX. fig. 23, and Plate XXXII. fig. 81.) 



Prom Grunong Inas, Perak State. Male. 



This specimen is, I think, identical with that from Tenasserira 

 described by Pocock. The colour is, however, slightly different. 

 The last joint of the antenna? is dark brown ; the head, antennas, 

 and first, tergite yellow-brown ; extreme edge of first tergite pale. 

 On each somite just above the keel there is a cluster of small 

 pale spots. The rest of Pocock's description applies. 



.STHONC4VLOSOMA BIPUKCTAITAL, Sp. UOV. (Plate XXX. fig. 16, 



Plate XXXI. figs. 43, 61, and Plate XXXII. iigs. 90, 95.) 



From Gunong Inas, Perak State, and Kuala Aring, Kelantan 

 State. 



Length 52 mm., width 6 mm. 



Colour of head dark brown, shading into yellow on the upper 

 lip ; under part of head yellow ; a patch of yellow just behind 

 each antenna. Anteuna? yellow, with the distal parts of the 

 joints shading into brown ; last joint dark brown. 



1st somite dark chocolate-brown, ends of keels and posterior 

 margin of tergite yellow ; ventral parts yellow. 



2nd somite same, but with brown patch on lower ventral part of 

 keel. Two pale spots on the prozonite. 



The 3rd 4' ^ l somites resemble the 2nd. On the 5th the pale 

 posterior margin is wanting, the chocolate-brown extending to 

 the, edge. On the cylindrical prozonite there are two large pal'' 

 >pdls separated by a dark - line. These spots are shaped like the 

 half of an oval and extend from the anterior margin of the pro- 

 zonite for about two-thirds of its length; they are visible up to 

 the 18th somil". 



Tin- tail is pah' at tin- posterior end, while at the anterior it 

 shows a pale band divided by a median longitudinal dark stripe. 

 At tin- ndes of the anterior end it is chocolate. I'll'- ventral 

 surface of the tail is pale and the anal valves chocolate. 



The body tapers anteriorlj and posteriorly. 



Head. Upper lip with a semicircular indentation, edged with
