Mijriopoda of the ^Challenger'' Expedition, 139 



Copulatory feet of the male as in fig. 9 h. 



Number of somites 45-46. 



Length about 40 millim. 



Loc. Cape Town (Simon's Bay). 



So far as colouring is concerned this species approaches 

 Sp. formosus of Porath ; but I infer from the description of 

 this last that the red dorsal bands are not continuous. More- 

 over, yy?-mos?^s is said to be " Iseve," and the anal valves are 

 compressed. In colouring again this species veiy much 

 resembles Sp. litoralis ; but in litoralis the whole head is 

 red and the dorsal spots are not continuous from segment to 

 segment. Porath mentions one specimen of litoralis (his 

 tessellatus) as coming from Cape Town and having a fuscous 

 band between the eyes. This example, I strongly suspect, is 

 in reality to be referred to this species.

Spiroholus challengeri^ sp. n. 

 (PI. IX. figs. 10-10 c.) 



Colour olivaceo- fuscous, most of the segments adorned 

 posteriorly and laterally with an inferiorly narrowed orange- 

 yellow stripe, which runs along the hinder margin, beginning 

 on a level with the pore and extending halfway towards the 

 legs ; legs and antennae narrowly testaceo-annulate. 



Head convex, shining, smooth or only very finely striolate, 

 with two pores on each side of the labrum, with a longitudinal 

 mesially nearly obsolete sulcus. Eyes subcircular, consisting 

 of about seven transverse rows of ocelli, separated by a space 

 equal to twice a diameter. Antetmce short, shorter than the 

 head, segments subequal. 



Eirst tergite smooth, its anterior edge lightly emarginate 

 on a level with the eye, the inferior angle wide, subacute, 

 with a faint anterior sulcus. The rest of the somites finely 

 striate laterally, the striaj falling far short of the pore, the 

 posterior portion smooth above, the anterior portion only very 

 finely striolate, the transverse sulcus visible only at tlie sides. 

 The pores conspicuous, situated just behind the position of 

 the sulcus, above the middle of the side. Scohina laro-e, 

 crescentic, extending from about the tenth to about the 

 fortieth segment, but very small towards the end of the body. 



Anal tergite smooth above and scarcely constricted, pro-
