Myriopoda of the 'Challenger^ Expedition. Ill 



anterior border and lateral angles ; upper Iialf of head U\%- 

 c(His, lower flavous ; antenna3 distally fuscous; legs flavous. 



Face smooth, indistinctly sulcate. Pores 2 + 2. Eyes 

 large, separated by a space that is about equal to a diameter. 

 AntenncB slender and longish, extending to the end of the 

 second segment. 



Collum laterally acutely angled, the posterior border 

 vertical, the anterior obliquely cut away and lightly emar- 

 ginate, the apex not reaching the inferior border of the 

 second. The rest of the segments lightly punctulate and 

 striolate above, the longitudinal striee of the lateral portion 

 extending almost up to the pore and passing on to the area 

 in front of the transverse sulcus ; this sulcus represented 

 dorsally by a shallow depression, sinuate opposite the pore, 

 which is situated in front of it above the middle of the side. 

 Sterna very finely striolate. Scohina absent. 



Anal tergite covering the valves but not surpassing them, 

 roundly angled ; valves lightly compressed, not marginate ; 

 sternite acutely triangular. 



Legs long and slender, with a single seta on the lower edge 

 of each of the first four segments, and a series of three or four 

 on the tarsus, not padded, 



Number of segments 50. 



Length 51 millim., width 4. 



A single male from Wokan Dobbo (Aru Island). 



This species falls into the same category with Sp. Goesi of 

 Porath, but the sculpturing is much finer and the colouring 

 very different. 



Spiroholus hiemorrhantus , sp. n. 

 (PI. IX. figs. 12, 12 a.) 



Colour (in alcohol) bright blood-red throughout. 



Face smooth ; sulcus mesially obsolete. Pores 2 + 2. Eyes 

 large, with upper inner border angular, separated by a space 

 slightly greater than a diameter. Antenme long and slender, 

 much longer than the face, surpassing the collum. 



Collum polished, acutely angled below, and projecting 

 nearly as far as the inferior portion of the second segment. 

 The rest of the segments smooth and polished behind dorsally, 

 at most lightly wrinkled longitudinally, striolate in front. No 

 scobina. The lateral striae extending in front of the transverse 

 sulcus and reaching almost up to the pore ; the transverse 

 sulcus obsolete or nearly so, represented by a shallow depres- 

 sion. The pjores minute above the middle of the side, in front 

 of the transverse sulcus ; sterna t-triate. 



The posterior end of the body noticeably compressed ; the
