524 MR. r. G. SINCLAIR ON THE [Dec. 3, 



lighter towards the inferior angle, where it is almost yellow. 

 Other somites : in front a greyish yellow, shading into a light 

 ash-grey as far as the transverse farrow ; after that the grey is 

 darker, becoming almost black posteriorly. This dark grey behind 

 the furrow is only continued down to the pores. Below the 

 pores the colour behind the furrow is ferruginous, with a tinge 

 of grey on the most anterior half. Legs and antennae clear orange- 

 yellow. There is a fine dorsal median longitudinal line ol: yellow 

 along the whole back. End of anal spike and edges of valves 

 orange-yellow. 



Head. Prontal furrow to level of eyes ; five labial pores. Space 

 between eyes 1| diameters. Anteiinse long, passing edge of 

 2nd tei'gite ; second joint longest, last two shortest. 



1st tergite. Postero-lateral edge striated ; five striae. Anterior 

 edge rounded and distinctly emarginate. Lateral edge very 

 narrow. Posterior edge straight. Other somites striated to level 

 of pore. Concentric markings anteriorly. Transverse furrow 

 well marked. 



Anal spilce short, sharp, and much upturned. 



Specimen Avith 51 somites. The colouring is not so bright. 

 The greys are not so dark and the ferruginous yellow is much 

 more marked, the head especially being almost castaneous. The 

 antennae are longer, reaching the 4th somite. 



Specimen with 53 somites. I believe, this to be adult. Length 

 215 mm. by 13 mm. The colouring is not so bright as either of 

 the first two specimens. The head is more black, the anterior 

 pai't of the somites is more yellow-grey. The black-grey of the 

 posterior part of the somite is continued further ventrally. 

 Behind the posterior part of the somite there is a very narrow 

 ring of castaneous. The thin line on the back is still apparent, 

 but is black instead of yellow. The narrowing of the body behind 

 the head is more apparent. The anal spike is somewhat blunter 

 though still uptui-ned. The antennae are dark brown, with a pale 

 yellow ring at the articulations. The legs are clear yellow, with 

 a black patch on the anterior and posterior aspects of each joint, 

 extending almost the whole length of the joint. The last joint is 

 black all round. The effect of this is curious. If a leg is looked 

 at from behind or from the front, it appears black with yellow 

 rings at the articulations and the last joint black ; when viewed 

 from the side, it appears altogether yellow with a black top joint. 

 The antennae reach to the hind edge of the 2nd tergite. The 

 second joint is the longest, the third longer than the fourth, 

 the fourth longer than the fifth, and the last two are the shortest. 

 The ventral grooves reach to the second joint of the legs. 



Altogether this Myriapod must resemble Sjp. oatesii Pocock 

 rather closely. The points in which it differs are : the length of 

 the antenna3 ; the number of ridges on the 1st tergite, though I 

 suspect this to be a peculiarity wliich differs in different individuals ; 

 the length of the ventral grooves ; and the anal process, which is 

 distinctly upturned in this animal. The legs are fairly long, but
