from the Chinese Seas. 355 



eighteenth segment, not beaded. The sulcus marking the 

 constriction not sculptured. 



Caudal 2^rocess truncate, triangular, not conspicuously 

 tubercular. 



A7ml sternite oval, the two tubercles not projecting beyond 

 the edge. 



The lateral surface lightly wrinkled, the inferior keel 

 distinct to the hinder end of the body, crescentic. 



The sterna., except at the anterior end of the body, with 

 two pairs of backwardly directed blunt spines, one at the base 

 of each leg. 



Legs with distinct claws, normally hairy ; femora about as 

 long as the tarsi, twice as long as the trochanters, but not 

 twice as long as the tibias. 



Length 35 millim. ; width across keels 3 8, width between 

 keels 3. 



Loc. A single female example from Chee Foo {Stvinhoe 

 Coll.). 



This species is perhaps allied to the Japanese Oxyurus 

 flavo-limbatus of L. Koch (Verb. z.-b. Wien, xxvii. p. 795, 

 1878), but the latter seems to have better developed keels 

 and to be differently coloured ; for the keels, including those 

 of the first segment, are said to be yellow, whereas in this 

 new form the first tergite is not yellow laterally and only the 

 posterior portion of the keels of the rest of the segments is 

 this colour. 



In colouring S. Swinhoei presents a strong likeness to two 

 other species, namely S. transverse-tceniatum of L. Koch, from 

 Australia, and S. Phipsoni, Pocock, from India. But in 

 neither of these two species are the sterna spined ; moreover, 

 in PMpsoni the first tergite is entirely bordered with yellow, 

 and in transverse-tceniatum the yellow band on the tergites 

 does not extend on to the keels.] 



\_Strongylosoma Holstii, sp. n. (PI. XI. fig. 3.) 



? . — Colour. Head and antennge black, the segments with 

 yellow just above and on the keels, and a large yellow spot 

 on the middle of each ; this yellow spot extends on to the 

 anterior part of the segments, and thus the series of them 

 forms a continuous median dorsal stripe; the lateral surface 

 black above, yellow below ; legs and sterna yellow. 



Antennce incrassate, with segments increasing in length 

 from 2 to 6, the sixth being noticeably longer than the 

 second. 



Body smooth above ; the heels small, just above the middle
