Mateiial examiried .—From, the Hamburg Museum: 3 specimens 

 (A) labeled '^Pheretima aspergillum E. Perr. China. Futschau"; 1 

 specimen (B) from a tube^ labeled ^^Pheretima {Ph.) siemsseni 

 Mich. Originale, China, Futschau. Consul Siemssen leg."; and 1 

 specimen (C) labeled "V 10472, Pheretima lauta Ude. China, Fut- 

 schau. Consul Siemssen." From the U. S. National Museum: 7 

 macerated clitellate specimens labeled "Foochow, China. C. R. 

 Kellogg, collector." 



Extei^al characteristics. — The setae begin on ii, on which segment 

 there is a complete circle. The setae are small and regularly spaced ; 

 no definite midventral break in the setal circles; a middorsal break, 

 when present, variable in width. The setal numbers are as follows: 



' Gaps in the setal row. 



s Gaps in setal circle in which setae may have been present. 



The first dorsal pore is on 11/12 (4 specimens — A and B). 



The clitellar glandularity is only slightly developed on the three 

 specimens of A; the clitellar coloration dark reddish, extending 

 from 13/14-16/17; intersegmental furrows and dorsal pores present; 

 setae visible at least ventrally. The clitellum of specimen C is also 

 probably not fully developed. The clitellum of specimen B appears 

 to be more completely developed, but there are slight traces of the 

 intersegmental furrows ventrally and also ventral setal pits in which 

 no setae can be seen. 



1 In addition, this tube contains a specimen of P. robusta and an acliteUate, softened, 

 and unidentifiable specimen of Pheretima sp.
