Genera and Species of Scolopendridse. 227 



cate ; the second as wide as the first ; from the fourth to the 

 twentieth bisulcate, the sulci, however, on the nineteenth and 

 twentieth being less conspicuous ; all the tergites with im- 

 raised margins ; the tergites lightly wrinkled, about as long 

 as wide, gradually increasing in length and width from the 

 fourth to the nineteenth ; the nineteenth is thus the largest of 

 all ; prescuta distinct. 



Sternites smooth, strongly and conspicuously bisulcate. 



Anal somite much smaller than the nineteenth ; tergite with 

 strongly raised margins, angularly produced posterior border, 

 not mesially sulcate, posteriorly depressed ; pleureenot porous, 

 not spined, almost concealed ; sternite very wide, as wide as 

 the nineteenth somite, projecting as far posteriorly as the 

 hinder border of the pleural, with convex posterior border ; 

 legs stout, not in contact, the segments subcylindrical and 

 becoming progressively more slender distally ; the patella 

 with a deep superior sulcus ; the claw not large, inferiorly 

 serrate, not spurred. 



Legs with unarmed tarsi ; claws armed with two spurs. 



Length 35 niillim., of antenna3 1^ millim. 



A single specimen from Perim Island, in the Red Sea, off 

 the coast of Abyssinia, collected by Mr. J. J. Walker, to whom 

 I have great pleasure in dedicating the species. 



Paeaceyptops, gen. nov. 



Closely allied to Cryptops, but differing in the following 

 respects : — 



Maxillary sternite furnished with two distinct, somewhat 

 rounded, prosternal plates. 



Claws of maxillipedes exceedingly short, so short as to be 

 incapable of meeting in the middle line. 



Paracryptops Weberi, sp. n. 



Testaceous, head and anal somite ochraceous. Body more 

 or less hirsute. 



Length 14 millim. 



Locality. Maumerie (Flores). Two specimens collected by 

 Dr. R. Max Weber. 



This new species will be fully described and figured in 

 Dr. Max Weber's ' Zool. Ergebnisse einer Reise in Nieder- 

 landisch Ost-Indien.'
