 Hope.) 



Cephalic segment cordate, subquadrate, depressed at the sides; antenna; much elongated ; 

 basilar segment large; mandibular tooth large, with a small tubercle near the apex; 

 labium with a triangular depression at its anterior part, sutures absent ; dental platen 

 transverse quadrate, with the anterior margin of each arched and a little dilated ; teeth 

 eight, very distinct, but obtuse. Posterior pair of legs elongated, triangular, with the 

 upper surface of the first three joints flattened, with thin elevated borders. Internal 

 margin of the basilar joint with six small spines arranged in two irregular subapproxi- 

 mated series; the posterior or angular spine large, elongated, and divided at its apt I 

 into six very minute ones: lateral and inferior surfaces of all the joints rounded, the 

 basilar one with nine small spines, arranged in three slightly diverging, longitudinal, 

 elevated series, three in each series, with a slight spoon-shaped excavation between the 

 middle and internal series at the base; fourth and fifth joints narrow and cylindrical. 

 Lateral anal appendages short, with the apex slightly elongated, quinqucfid, with the 

 posterior margin compressed, and a minute tubercle on its external surface near the 

 base of the legs. Preanal scale quadrate, subcordate, with the margin straight. 



This species beats a very close resemblance to $. Leachii, but is distin- 

 guished from it by the rounded terminal joints of the posterior legs, the tu- 

 bercle on the anal appendages, the elongation of the antenna-, and the greater 

 length of its body. It was captured at Port Essington in Australia, and I may 

 here remark that a great similarity exists between many of the Scolopendra* of 

 the north-western coast of Africa and those of the Australian continent.
