The intestine begins in xv. The intestinal caeca are long, slender, 

 and simple, dorsal and ventral margins practically smooth. 



There is a single heart belonging to ix, on the right side. The 

 hearts of x are bound to the anterior face of 10/11 by connective 

 tissue. The last pair of hearts is in xiii. All hearts of ix-xiii pass 

 into the ventral vessel. 



There are two testis sacs on the anterior face of 10/11, the sacs 

 completely separated from each other and without transverse com- 

 munication. There is also a pair of testis sacs in xi without trans- 

 verse communication. The seminal vesicles are either attached to the 

 dorsal surfaces of these testis sacs or are contained within the sacs. 

 The prostates extend through xvii-xix. The prostatic duct is about 

 514 imn in length and variously twisted. 



The spermathecal duct, which is abruptly narrowed deep in the 

 parietes, is stoutish, firm, and glistening, as long as or slightly 

 shorter than the ampulla. The diverticulum passes into the anterior 

 face of the duct in the parietes, is shorter than the combined lengths 

 of duct and ampulla, and comprises a very short, firm, smooth, 

 glistening stalk i)ortion and a slightly wider, more irregular, ental 

 portion. 



There are no glandular masses in the parietes in the region of the 

 spermathecal ducts and the prostatic ducts. Tliere is a glandular 

 mass sessile on the parietes over each genital marking. 



Remarks. — The condition of the right male pore region and the 

 distribution of the setae indicate that the specimen is abnormal. 



The type locality is Yachow, according to Dr. Graham {in litt.)^ 

 not "Zachoo" as previously spelled (Gates, 1935, p. 13). 



P. pa-'pWifera is distinguished from P. ahdita by the superficial 

 male pores, from P. tuherculata Gates, 1935, by the sunple intestinal 

 caeca, and from P. hawayana by the genital markings on xi-xiv.
