lUUl.J Ml'lUAPOD.V OF THE " SKEAT EXPEDITION." 519 



by xittems under the uame nodiilosum. 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 Attenis 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 chitinous 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 setiferons tubercles in the same 

 place as in Platyrhacidse and the two pairs o£ setiferons tubercles 

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

 the figure. 



Strongylgsoma (Oethomobpha) euscooollaris Pococlc. ( Plate 

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



Eroui GuDong Inas, Perak State. Male. 



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

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

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

 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. 



Strongylgsoma bipunctatum, sp. nov. (Plate XXX. fig. 16, 

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



Erom Grunong Inas, Perak State, and Kuala Ariug, 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. Antennae yellow, with the distal parts of the 

 joints shading into brown ; last joint dark brown. 



Ist 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 Sf 4f7i 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 pale 

 spots 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 somite. 



The tail is pale at the posterior end, while at the anterior it 

 shows a pale band divided by a median longitudinal dark sti-ipe. 

 At the sides of the anterior end it is chocolate. The ventral 

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



The body tapers anteriorly and posteriorly. 



Head. Upper lip with a semicircular indentation, edged with
