ART. 7. — S. TANAKA : 



caudal sheath and in the spots on body being somewhat irregular 

 in outline and rather indistinct. It is not altogether impossible 

 that the differences here pointed out are due only to difference 

 of sex in one and the same species, but unless evidences are 

 forthcoming in support of that view, the specific distinction 

 might be maintained without impropriety. 



The type is the only specimen known. It was obtained in 

 Kagoshima, Province of Satsuma, in 1903 and is now contained 

 in the museum of the Zoological Institute under Mus. No. 957. 

 The species is named for Mr. K. Nagayo, assistant to Mr. 

 Alan Owston of Yokohama.
