268 Mr. G. Newport on new species of Myriapoda. 



penultimate segment with a strong, curved, acute mucro. Length 

 1^ inch. Canada, 



6. /. parvipes, mihi. Bluish black, polished ; segments sixty-six ?, 

 with .the posterior half of each with very faint longitudinal strise ; 

 legs very short and slightly hairy ; penultimate segment with a 

 straight, elongated, acute point ; lateral anal plates with deep 

 hairy punctures. Length 2 to 2^ inches. Valley of the Xanthus, 

 Asia Minor. 



7. — londinensis, Leach. 



8. — pilipes, mihi. Colour of dried specimen white ; segments sixty- 

 three, longitudinally striated, with the posterior margin black, or 

 reddish ; legs rather short, fuscous, densely ciliated, penultimate 

 segment with a very short, acute apex; the foramina repugnatoria 

 minute, black. Length 3^ inches. Country ? 



9. — punctatus. Leach. 



10. — pusillus. Leach. 



11. — Sayii, mihi; I. pusillus, Say. Flesh-coloured, with a black 

 patch at the side of each segment ; eyes black, arranged in a trans- 

 verse arched line, with the concavity forwards ; antennae short, 

 clavate ; segments smooth, without strise, the penultimate one with 

 the apex rounded. Length 6 lines. North America. 



This description is taken from Say's original specimen, which, 

 however, is not an adult. It has but forty-five segments, the 

 three antepenultimate of which are apodal. 



Genus Blaniulus ? Gervais. 



1. B. pulchellus. Leach, (sp.) 



Although I have placed this species in a separate genus, accord- 

 ing to Gervais, it yet seems doubtful whether it ought not rather 

 to form only a section of the luli^ with which it agrees in every 

 respect except in the absence of eyes. 



Genus Spirobolus, Brandt, 



1. S. olivaceus, mihi. (Div. 1. Subdiv. 1, a, Brandt) Body short, 

 thick, dark olive, with the prothorax subferruginous; legs dark cho- 

 colate ; front convex, smooth, with a median labial sulcus ; segments 

 forty-four, smooth, with the posterior half of each very short and 

 distinct, with obsolete strise ; preanal scale triangular, with the 

 apex acute, with a deep transverse depression at its base. Length 

 8 inches. Oajaca, Mexico. 



This species ought perhaps to form the type of a distinct sub- 

 genus, since the second, third, fourth, fifth, six and penultimate 

 segments each bear only one pair of legs. 



2. S. pulvillatus $ , mihi. Front of the head flattened, with the la- 

 bial margin dilated and acute at its angles, with a median sulcus ; 

 segments fifty-seven, smooth, the posterior half of each without 

 striae ; legs strong, with the distal or third joint of the tarsi more
