chamberun: iiyriopoda of the Australian region. 41 

 ventral plate of intermediate width, braperiform, strongly narrowed caudad; 



caudal margin short, straight. 



Cozopleural pores do1 crowded, aboul sixteen in Qumber on each side, 



distributed over ventral and lateral surfaces and anteriorly extending upon 

 the dorsal surface. Claw of anal legs long. 



Fairs of legs, forty-one. 



Length, 32 nun. 



97. Zelanion curtus, sp. nov. 



Type — M. C. Z. 2,057. New Zealand: Taumarunni (W. M. 

 Wheeler). 



This speeies is very similar in general coloration, appearance, and 

 structure to Z. dux. The antennae are shorter and the last article 

 equals the two preceding taken together instead of being clearly shorter. 

 The cephalic plate is longer, being 1.6 times longer than wide as against 

 1 .45 times in dux; the plate is also differently shaped, being more grad- 

 ually and uniformly narrowed from near the middle caudad, the nar- 

 rowing in dux beginning farther caudad and much more abrupt, mak- 

 ing the caudal corner strongly oblique. Two furrows on posterior 

 portion of plate impressed with puncta which are also scattered else- 

 where. 



Basal plate much overlapped by the cephalic, the exposed portion 

 very short as in Z. dux. Prosternum and prehensors very similar 

 to those of the other species. The prosternal teeth more divergent, 

 the mesal edges separating more widely from the median line. 



First legs proportionately much less reduced than in Z. dux, being 

 scarcely shorter, though more slender, than the second. 



A median longitudinal furrow deep and distinct on anterior ster- 

 nites but absent farther caudad, not persisting distinctly as in Z. dux. 



Coxopleural pores larger and fewer than in Z. dux and not extending 

 to the dorsal surface. 



The species has fewer legs, — thirty-nine pairs as against forty-nine 

 or fifty-one in Z. dux. 



Length, 24 mm. 



98. Zelanion (Zelanoides) similis, sp. nov. 



Type.— M. C. Z. 2,058. New Zealand: Day's Bay near Welling- 

 ton (W. M. Wheeler). 



Color of body and legs, fulvous; the dorsum darker, anteriorly and poste- 

 riorly of ferruginous tinge; head prehensors and antennae dilute ferruginous.
