12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 93 



Septa 8/9-9/10 present and thickly muscular. Intestinal caeca 

 simple. Testis sacs of x and xi unpaired. Spermathecal diverticulum 

 with a muscular stalk and an elongate seminal chamber, the ectal 

 portion of the latter looped, the ental portion ovoidal. Genital marking 

 glands sessile. 



Type. — U.S.N.M. no. 20102, Suifu, Szechuan. 



Distinguished from P. zoysiac Chen, 1933, by the presence and 

 muscularity of septa 8/9-9/10 and by the presence of genital markings. 



PHERETIMA MIRABILIS (Bourne), 1887 



In the synonymy of this species there must now be placed P. lictcro- 

 chaeta (Michaelsen), 1891. and P. d'wcrgcns var. yunnancnsis Ste- 

 phenson, 191 2. 



PHERETIMA MODESTA Michaelsen, 1927 



The male pores are in copulatory chambers which, in a completely 

 retracted condition, protrude rather conspicuously into the coelom. A 

 very large portion of the coelomic protuberance is composed of tiny 

 quirks in the prostatic duct on the dorsal face of the chamber and a 

 mass of connective tissue surrounding these quirks. The lumen of 

 the chamber is rather small but is narrowed in the outer layers of the 

 parietes as if by a contraction of an annular, sphincter muscle. In 

 slightly softened specimens the apertures of the chambers gape open, 

 and the lumen of the chamber does not extend internally beyond the 

 level of the coelomic face of the parietes. 



In the synonymy of P. iiiodcsfa are to be placed P. kiangensis 

 Michaelsen (in part only?) and P. hcspcnduni Chen, 1931 and 1933. 

 The status of Beddard's P. hesperiduui was discussed in Gates ( 1932) . 

 Stephenson (1933) considered the status of P. hcspcridum and has 

 also refused to accept Beddard's species. 



PHERETIMA OBSCURITOPORA Chen, 1931 



Erected on juvenile specimens of uncertain age, in which the adult 

 and hence definitive specific characteristics are unrecognizable. The 

 Szechuan specimens might be rather small juveniles of P. grahami or 

 P. pracplngnis; the Nanking specimens may possibly belong to 

 P. tschilioisis. 



PHERETIMA OMEIMONTIS Chen, 1931 '■ 



P. piiragJandidaris var. oincinioiitis Chen, 1931, is distinguished 

 from P. paraglandnlaris Fang, 1929 (= P. aspergillitiii), by dififer- 

 ences so numerous and significant that oiucimontis must be regarded 

 as specifically distinct.
