34 bulletin: museltm of comparative zoology. 



Prebasal plate exposed. 



Basal plate broader than cephalic, bent somewhat forwards at ends. 



Claws of prehensors when closed extending to end of first antennal article. 



Spiracles vertical, sUt-Hke. 



Last ventral plate wider than long. Coxopleurae as usual. 



Anal legs very obviously exceeding the penult in length. 



Pairs of legs, one hundred and ninety-one. 



This species is more slender than A.aiopus and has a larger number of 

 pairs of legs. Aside from the family characters it is distinguishable in 

 having the prescutum of the last leg-bearing segment separated off only 

 by a weak sulcus, the fusion being nearly complete; sulcus bowed 

 caudad as usual, rounded at middle. Also in having prebasal plate ex- 

 posed, no frontal suture, and anal legs longer than penult. 



85. GONIBREGMATUS FIJIANUS, Sp. nOV. 



TiPE.— M. C. Z. 1,908. Paratypes.— M. C. Z., 1,909, 1,958. 

 Fijis: Nadarivatu, Vanua Ava (W. M. Mann). 



General color fulvous throughout. 



Head clearly broader than long (43:38); anterior border and posterior 

 border subtriangular, the anterior margin mesally more rounded. Frontal 

 suture present; also a suture across the caudal border. Clypeal region with 

 a broad median longitudinal ridge ; labrum strongly convex about caudal end 

 of ridge. 



First articles of antennae flattened, broad, narrowing distad; distal article 

 distally blunt. 



Last ventral plate wider than long, posteriorly truncate, anteriorly convex. 



Anal legs small, not exceeding the penult in length, last four articles essen- 

 tially equal in length. Prescutum of last leg-bearing segment separated by a 

 deep sulcus forming an obtuse angle with apex caudad. 



Segments near one hundred and seventy-seven. 



Length of type, near 150 mm.
