Aberration?. — A sirig;le specimen (No. 33) in the Zoological Museum 

 in Copenhagen, which I had the opportunity to examine in 1905 

 owing to the kindness of Inspector Jensen, was received in 1847, 

 probably from Schlegel in Leiden, and is labeled "Japan." It is in 

 every respect a ty})ical //. nehulosus, except that it has only 4 well- 

 developed toes, the ruchment of the fifth toe being scarcely noticea- 

 ble. It consequently holds the same relation to H. nehulosus, as H. 

 peropus to //. nxvius; in fact, the rudiment of the fifth toe is even 

 smaller than in Boulenger's figure of H. peropus."- It has the vomero- 

 palatine series very long and 13 costal grooves. 



The lack of the toe being the only character, I do not regard tliis 

 specimen as representing a distinct form or species. 



Hahitat. — This species was originally described from specimens col- 

 lected by von Siebold at Mits yama, near Nagasaki. A specimen 

 from the latter jilace is also in the Senckenberg Museum. Siebold 

 also indicates its occurrence in Hondo and wShikoku, though some- 

 what indirectly.^ A young specimen collected by C. Maries at Nikko, 

 Hondo, is in British IVIuseum, and Nikko specimens are also in the 

 Science College Museum in Tokyo (No. 51). 



Sclater records three specimens in the Indian Museum as collected 

 by Dr. J. Anderson in Yezo, but this is probably an error for Yedo, 

 as there is no corroboration of its occurrence in the northern island. 



British Museum has specimens (No. 92. 1. 11. 18; female and 

 larva*) collected by Hoist in Tsu-shima, the female on October 6, 1891, 

 the larvjie on August 7.
