NAGAMICHI KURODA: 



29. Apodemus geisha holckaidi (Thomas). 



Two males (Nov. 8 & 19, 1916) and two females (Nov. 20, 1916) 

 obtained by Mr. H. Orii near Tomakomai in Hokkaido. Length of 

 ear in these specimens, as measured by Mr. Orii, from 12 mm. to 12.5 

 mm. Mr. Aoki united the Hokkaido form with the typical Hondo 

 form, but in my opinion, Thomas is quite right in distinguishing the 

 two subspecifically. 



30. Apodemus speciosus speciosus (Temm. & Sehl.). 

 One female specimen from Togane, Prov. Kazusa, Nov. 27, 1918. 



31. Apodemus speciosus ainu (Thomas). 



Three males (Dec. 5, 1916) and two females (Nov. 21 & 28, 1916) 

 collected by Mr. H. Orii at the same locality with A. geisha hokkaidi. 



32. Rattus rattus rattus (Linnaeus). 



Two males and one female obtained in Tokyo, May 8, 1908. 

 According to Mr. Namiye, the rat is restricted in its distribution to 

 the neighbourhood of Tokyo. 



33. Rattus rattus aleocandrinus (Geoffroy). 

 Several specimens obtained in Tokyo and at Haneda. 



34 Rattus norvegicus (Erxleben). 



Six specimens captured at Haneda. Mr. T. Nibe sent me nine 

 young specimens of this rat from Hanatate, Prov. Ugo; Nov. 11 — 19, 

 1915. 



35. Mus molossinus Temminck. 

 Two adults and two very young specimens sent me by Mr. T.
