Mr. Newport on the Class Myriapoda, Order Chilopoda. 425 



The apical spine of this species is slightly elongated, and trifid at its apex ; and the four 

 spinulae on the inferior external margin are arranged in two subapproximated pairs, 

 and the two on the internal margin in a single longitudinal series. The lateral anal 

 appendages are deeply punctm'ed and elongated, with the apex bifid. Preanal scale 

 subquadrate, with the posterior margin almost straight. 



12. Corm. lineatus (Tab. XL. fig. 11.), sordide ochraceus, superficie dorsali lineis 5 longi- 

 tudinalibus elevatis, pedibus postremis clavatis ; articulo basali brevissimo conico spina 

 unica angulari minuta articulisque omnibus sulco longitudinali profundo in superficie 

 sujjeriore versus extremitatem distalem. — Long. unc. l^^. 



Hab. In Insula Caribaea S*' Vincentii, Guilding. {v. in Mus, D. Hope.) 



The antennae of this species are very thick at their base, with the joints short, as in Geophilus ; 

 the labium is narrowed anteriorly, and marked with a triangular impression ; the dental 

 plates are distinct and elongated, with an elevated median crest ; the teeth six, sub- 

 obsolete, the external one most distinct ; the posterior legs are clavate, rounded, with 

 the basilar joint conic, much shorter than the second joint and rounded, without spines 

 on the inferior surface. The lateral appendages punctured; and the preanal scale 

 cordate, with the posterior margin rounded. 



13. Corm. Guildingii, ochraceus, superficie dorsali lineis 2 longitudinalibus impressis di- 

 stantibus, pedibus postremis clavatis maximis elongatis ; articulis aequalibus longitudi- 

 naliter impressis ; basali conico : superficie interna complanata serie obliqua spinarum 

 3 minutarum totidemque in margine articulari distali : superficieque inferiore spiuulis 3 

 in linea obliqua elevata dispositis. — Long. unc. 1. 



Hab. In Insula Caribaea S*' Vincentii, Guilding. [v. in Mus. D. Hope.) 



The dental plates of this species are distinct, but the teeth vtery minute. The lateral anal 

 appendages smooth, with the middle internal surface roughened with a multitude of 

 minute tubercles. Preanal scale subquadrate, with the margin rounded. 



The species is named in honour of the late Rev. Lansdowne Guilding, by 

 whom this species and C. lineatus were collected.
