60 REPORT ON THE CENTIPEDES AND MILLIPEDES OBTAINED BY 



the right side being independent of and disconnected from that of the left. But in 

 Gonibregmatus each mandible consists of an outer and of an inner branch, the former 

 corresponding to the normal biting mandible of the rest of the class. The inner branch 

 is united to its fellow of the opposite side, though the junctional suture persists, and 

 the plate that results from the union constitutes physiologically a lower lip or labium 

 designed presumably to prevent the escape of fluids issuing from wounds inflicted by 

 the outer branches of the appendage. The mouth lies some distance behind the tip 

 of this lower lip or labium and of the upper lip or labrum, and these two structures 

 constitute the upper and lower walls of a channel which is closed at the sides by the 

 outer branches of the mandible ; the mandibles, labium and labrum thus form a kind 

 of proboscis along which the fluid tissues of prey flow or are sucked backwards to the 

 mouth. 



Class. CHILOPODA (Centipedes). 



Order. SCUTIGEROMORPHA. 



Family. Scutigeridae. 



(1) Scutigera metadata, Newp. 



Ann. Mag. Nat. Hist, xiil, p. 96, 1844; Tr. Linn. Soc. xix., p. 359, 1845. 

 Loc. New Britain, 



The specific identity of the two specimens obtained by Dr Willey in New Britain 

 must be regarded as doubtful. Both are of small size and more or less damaged. 

 This species has been formerly recorded from Australia. 



Order. SCOLOPENDROMORPHA. 



Family. Scolopendridae. 



Genus. Scolopendra, Linn. 

 (2) Scolopendra metuenda, Pocock.

 Loc. Narowol, (Eddystone) Solomon Islands. 



The type and hitherto only known example of this species was obtained in New 

 Georgia, in the Solomon Islands, by the officers of H.M.S. ' Penguin.' 



Genus. Cormocephalus, Newport.
