346 NOTES ON MYRIAPODS. 



When compared with E. erythrqpygus this new geographical species 

 plainly differs from it by the characters given. The lateral margiu of 

 carinas are also slightly crenulate and the anterior is somewhat serrate. 

 Length, 28 mm ; width, 3.4""". 



The exceedingly long branch of the copulation foot at once separates 

 australis from the true erythropygus. The inner tooth is also absent, 

 but this is subject to slight variations in. erythropygus. 



The above notes are taken from a male which is slightly broken. 



19. Polydesmus branneri Bollmau. Ace. 1954*2, 23, Tallulali, Ga.; L. M. Under- 



wood. 

 These specimens are all females, and I refer them to this species with 

 some doubt, but as they are from the region in which P. branneri is 

 found they must belong to that species and not to P.serratus, which is 

 not quite so southern in its range. 



20. Polydesmus serratus Say. Marksville and Natural Bridge, Va.; L. M. Under- 



wood. 



21. Linotaenia chionophila Wood. ? No. 89, U. S. Nat. Mus. Washington, D. C. ;

22. Linotaenia fulva Saeger. Ace. 19542, 15, Indian Springs, Ga. ; L. M. Under- 



wood.

23. Linotaenia parriceps Wood. Ace. 17414, Baird, Shasta County, Cal. ; L. M. 



Green. 



Pairs of legs of male 79. 



24. Geophilus foveatus McNeill. Lookout Mountain ; L. M. Underwood. 



Pairs of legs of female 43; pleural pores less numerous than in the 

 northern specimens.

Diagnosis. — lielated to G. mordax, but on the anterior ventral plates, 

 especially the 7-1 3th, an ovate depressed poriferous area along the an- 

 terior margin, into which projects a conical elongation of the preceding 

 segment ; coxa- of prehensorial legs of about equal length and breadth. 



Habitat. — Natural Bridge, Va.; L. U. Underwood. 



Type. — U. S. Nat. Museum. 



As is indicated by the above diagnosis this new species is closely re- 

 lated to G. mordax. 



My specimen is a male, and as G. mordax is described from a female, 

 the following secondary differences are worthy of notice : 



Anal legs moderately crassate, densely and shorty pilose; claw 

 large ; pairs of legs 49 ; length 35'" m . 



If the characters given in the diagnosis are those peculiar to a male, 

 this new species must be identical with mordax, but the proportions of
