Mr. R. T. Pocock on new Species of Chilopoda. 153 



armed, armed beneath as follows — 0, 1, 3, 3, 1 ; coxee of the 

 three posterior pairs armed with a conspicuous lateral spine ; 

 coxal pores in the adult elongate, arranged in a single series 

 as follows — 8, 8, 8, 7 or 6 (in the young the pores are 

 rounder and 5, 5, 5, 4). 



Generative forceps in female with two spurs on each side 

 and a trifid claw. 



Length up to 29 millim. 



Four specimens from Bermuda {^Challenger''). 



This species is evidently allied to foi-Jicaius, but it differs 

 at least in having the three posterior coxa3 armed with a 

 lateral spine. 



Lithohius (s. s.) sydneyensis^ sp. n. 



Colour * ochraceous. 



Eyes composed of about 10-15 ocelli, arranged in three or 

 four rows approximately as follows — 1 + 5 or 4, 5 or 4, 

 4 or 3. 



Antennm moderately long, hairy, composed of 26-28 seg- 

 ments. 



Maxillary coxcb mesially impressed, with 2 + 2 conspi- 

 cuous teeth, excised in the middle line. 



Tergites more or less wrinkled, in the posterior half of the 

 body distinctly granular ; angles of the ninth, eleventh, and 

 thirteenth strongly produced. 



Sternites sparsely hairy, not mesially impressed. 



Legs hairy and spinous ; the first pair armed below as 

 follows — 0, 0, 1, 3, 1 ; anal legs robust, only a little longer 

 than those of the preceding somite, armed beneath as follows 

 — 0, 1, 3, 3 or 2, 1 ] coxa without a lateral spine ; upper 

 surface of the patella of the male furnished at its distal end 

 with a nodular projection, which is hollowed out above; coxa3 

 of the four last legs furnished (in the adult) with 6, 7, 7, 5 

 elongate pores, arranged in a single series. 



Generative forceps of the female with two long spurs on 

 each side and a slender, lightly bifid claw. 



Length 19 millim. 



Four specimens (1 ?,3 (J) from Sydney, presented by 

 Mr, John Brazier. 



I believe this to be the first species of the genus recorded 

 from Australia. Dr. Newport described one species named 

 argus f from New Zealand ; but L. sydneyeasis is very 



* Possibly faded from long immersion in spirit. 



t The type of L. argus, which is preserved in the Hope Museum at 

 Oxford under the name zelandicus, shows that the species is referable to 

 Lithohius sensu stricto. More than this I was not able to determine in the 

 hm-ried examination that I was able to give the specimens.
