362 Mr. R. I. Pocock on Ghilopoda and Diplopoda 



This species is very nearly related to F. Doenitzi of Karsch 

 (Zeitschr. Naturvvissen. (3) v. p. 848, 1880), which is also a 

 Japanese form. The two agree apparently in length, in proxi- 

 mity of the keels, colours, and in a general way in the form of 

 the copulatory apparatus ; but in Karsch's description of this 

 latter structure no mention is made of a spine halfway along 

 the length of the organ, and the apex is said to be acute, 

 without any word to imply that it presents the complicated 

 trifurcate extremity presented in this new form. 



Fontaria Martensii, Peters (Mon. Ak. Wiss. Berlin, 1864, 

 p. 536), from Yokohama, is, like Dmnitzi^ unknown to me; 

 but judging from its description and from what Karsch [he. 

 cit.) has said about it, there seems to be no reason for 

 supposing it to be identical with any of the species described 

 below.] 



[^Fontaria^ sp. 

 Loc. S.E. Corea [Alfred Carpenter).'] 



[Fojitaria, sp. 

 Loc. Tsu-Shima [Hoist Coll.).'] 



These two species are represented in the collection by soli- 

 tary female examples. I consequently refrain from describing 

 them. 



I have entirely failed to identify the following species of 

 Polydesmidse : — 



1. Strongylosoma carinulatum, Motschulsky, Bull. Nat. 



Mosc. xxxix. (1866) p. 200. From Japan. 



2. Strongylosoma japonicum, Peters, Mon. Ak. Wiss. 



Berlin, 1864, p. 536. From Yokohama. 



3. Paradesmus pekinetist's, Karsch, Arch. Nat. 1881, 



p. 39. From Pekin. Certainly differs from any 

 that I have described in the granulation of its first 

 tergite. 



4. Oxyurus Jlavo-UmbatuSj L. Koch, Verb. z.-b. Wien, 



xxvii. p. 795. From Japan. 



5. Oxyurus rosulans, Tomosvary, Term. fUzetek, ix. p. 69. 



From Japan. 



I have not seen a single example of the genus Oxyurus 

 from the Chinese region. Perhaps the species named rosulans 

 is a Fontaria.
