358 Mr. A. G. Butler on new Myriopoda. 



nnclial plate without punctures ; dorsal segments, excepting 

 the last (which is delicately rugose), without punctures; all, 

 excepting the first and last, longitudinally multisulcate. 



Length 1 inch 11 lines to 1 inch 4 lines ; width 1 inch to 9 

 lines. 



Hah. Borneo (TF". e/m^es). Eight specimens. B.M. 



One example shows scarcely a trace of the sulcations on the 

 dorsal segments. 



Genus Sph^rotherium, Brandt. 

 1; Sphcerotherium latum^ n. sp. PL XVIII. fig. 3. 



Castaneous, dotted here and there with blackish ; mouth 

 black ; eyes crystalline white. 



Head rugose and densely punctured in front, coarsely but 

 sparsely punctured in the centre ; nuchal plate sparsely punc- 

 tured ; dorsal segments delicately rugose, last segment also 

 sparsely punctured. 



Length 2 inches 1 line ; width 1 inch 3 lines. 



Hob. North Madagascar {L. Bouton). One specimen. B.M. 



Allied to >S'. Actceon of White ; but smaller, paler in colour, 

 more depressed in outline, less rugose, and with lateral wings 

 of segments less curved. The antennse in S. Actceon are broken, 

 which accounts for Mr. White not having more than hinted at 

 its genus by comparing it with S. Jiippocastanum^. 



2. Sphcerotherium Neptunus, n. sp. PI. XVIII. fig. 6. 



Olive-green, clouded and blotched with pale ochreous; the 

 external margins of the segments dark ochreous. Variety 

 pitchy, clouded with castaneous ; the external margins of the 

 segments castaneous. 



Head coarsely and densely punctured in front, sparsely 

 behind ; nuchal plate with row of coarse punctures in front and 

 two or three punctures behind ; dorsal segments smooth and 

 shining, the last sparsely punctured. 



Length 2 inches to 4^ lines ; width 1 inch to 2 lines. 



Rab. Madagascar {Madame Ida Pfeiffer) ; Port Natal 

 {Oueinzius). Eight specimens. B.M. 



Allied to 8. rotundatum of Brandt, and agrees in many 

 respects with the description of S. Titanus 5 but the last segment 

 is not peculiar in shape. 



* A Zephronia (!) in the British Museum agrees pretty well with the 

 description of the latter species ; it will, however, doubtless prove to be 

 distinct when an opportunity occurs of comparing it with authenticated 

 examples of that species.
