Mr. li. I. Pocock on new Species of Ghilopoda. 157 



Anal somite. — Tergite and sternite of normal form ; tlie 

 pleurce furnished below and in front with a number (about 

 thirty) of larger and smaller pores, posteriorly smooth and 

 armed with stout spiniform hairs. Legs : femur and patella 

 armed beneath (except in the middle) and internally witli 

 subserially arranged spines, superior posterior angles sliglitly 

 produced ; tibia much shorter than the patella, armed above 

 and behind with two sharp spines, beneath with a row of 

 about eight short tooth-like spines ; first tarsal segment armed 

 below with a row of about three tooth-like spines ; second 

 tarsal segment carinate in its posterior two thirds. 



LegSy especially at the posterior end of the body, armed 

 with stout spiniform hairs. 



Length 24 millim. 



Two specimens from Sydney, presented by Mr. John 

 Brazier. 



This species is very closely allied to Or. sulcata of Haase, 

 but differs in that the longitudinal dorsal sulci are not visible 

 on the first and second tergites, but take their origin from 

 the hinder half of the third. 



In sulcata, which is also an Australian species, these sulci 

 are complete on the first, second, and third tergites. 



Gryptops setosus, sp. n. 



Colour ochraceous. 



Body robust, thickly and coarsely punctured throughout, 

 and hairy. 



Head marked throughout by two tine anteriorly diverging 

 sulci. 



Antennce short, hairy throughout, composed of 17 stout 

 segments. 



First tergite covered in front by the head, marked ante- 

 riorly by a strong transverse sulcus, not longitudinally 

 sulcate. 



Maxillary coxoi with lightly convex, mesially excavated, 

 anterior border, furnished on each side with about four sette ; 

 claws long and slender. 



Tergites (except the first three and the last two) quadri- 

 sulcate, the lateral sulci beginning at the second, the nine- 

 teenth tergite with lateral sulci, but with very short median 

 sulci ; all the tergites except the last ^vith unraised margins. 



Sternites marked with a cross-shaped sulcus, the longitu- 

 dinal sulcus, however, being nearly obsolete behind and 

 abbreviated in front.
