the first setigerous somite, but probably this was due to the poor 

 condition of the specimen and the less of some of the somites. 



Family LEODICIDAE 



Genus DIOPATRA Audouin and Milne Edwards 



DIOPATRA NEAPOLITANA Chiaje 



Diopafra neapolitana Chiaje, 1841, p. 97. — Fatjvel, 1932b, p. 144; 1933, pp. 28- 

 37, fig. 4, a-d. 



One specimen (Chen no. 34). 



Genus LYSIDICE Savigny 



LYSIDICE COLLARIS Ehrenberg, Grube 



Lysidice collar is Grtjbe, 1868, p. 633; 1869, p. 495.' — von Marenzeller, 1879, 

 pp. 136-137, pi. 5, figs. 2, 2A, 2B. 



Two specimens (Chen nos. 28, 35), one incomplete, identified from 

 von Marenzeller's description. 



Genus LUMERINEREIS Blainville 



LUMBRINEREIS HETEROPODA (von Marenzeller) 



Lwrn&r/conerfzs /leieropoda VON Marenzeller, 1879, pp. 138-139, pi. 5, figs. 4, 4A, 

 4B;pl. 6, figs. 1, lA, IB. 



A single incomplete specimen (Chen no. 33) retaining about 50 of the 

 anteriormost somites. The onl}^ differences that I could discover 

 between this and von Marenzeller's description are that the teeth on 

 the large maxillary plate are heavier than in the Japanese specimen 

 and that hooked setae occur in somites anterior to the thirt^^-fifth. 



Genus MARPHYSA Quatrefages 



MARPHYSA SINENSIS Monro 



Marphysa sinensis Monro, 1934, pp. 367-369, fig. 5. 



The two specimens (Chen no. 45) agree with Monro's description in 

 the apparent absence of pectinate setae in the anterior somites and 

 in the presence of compound setae whose terminal joints sliow^ a faint 

 longitudinal grooving (Monro's fig. 5E). In other species of Marphysa 

 the pectinate setae are hard to find in anterior somites, so that the 

 peculiar compound setae are possibly the only essential difi'erence 

 between this species and M. belli Audouin and IMilne Edwards. It 

 might be questioned if this difi'erence is of specific value and whether 

 M. sinensis should not rather be listed as a variety of AI. belli. 



MARPHYSA ORIENTALIS, new species 



The type and only specimen is 200 mm long and has a prostomial 

 width of 3.5 mm and a peristomial width of 5 mm. From the pro- 

 stomium the body graduall}'^ widens to about the fortieth somite,
