HEEPETOLOGY OF JAPAN. 243 



from Yezo, and in many of the specimens from Kiiisiu and Shikoku, 

 the granules are so much developed as to entirely separate both the 

 first and the second supraoculars from the outer series of elongated 

 superciliaries (fig. 209). In the majority of the specimens from the 

 southern lowland localities I also find several granules bordering the 

 anterior end of the first large supraocular. In the Hondo specimens 

 there is a greater uniformity inasmuch as in nearly every one of these 

 the first large supraocular is broadly in contact with the long supra- 

 ciliary. There is not enough constancy in these characters to base a 

 separation upon them, and it should be noted that the relation of these 

 shields in the southern specimens tends in a direction away from 

 T. holsti rather than toward it.*^ 



The coloration varies considerably; the male described above shows 

 almost a maximum of dark and light markings, the female has the 

 markings nearly obsolete except on the sides of fhe head; between 

 these extremes there are all transitional stages, though the females 

 are less heavily marked than the males; in many specimens the pale 

 dorso-lateral Ime is more definitely marked than in the one described ; 

 in others it is more or less broken up b}^ dark spots from the adjoining 

 dorso-lateral black line; the sides are often solidly dark brown, in 

 other specimens again more or less marked with pale or whitish spots. 



Habitat. — The present form of grass lizard is apparently restricted 

 to Ja]ian proper. The range was formerly thought to include the 

 adjacent portions of the mainland, but these are inhabited by other 

 species, such as T. septentrionalis and T. wolteri, with which it was at 

 one time confounded. 



The tA'pes came from the neighborhood of Nagasaki, and it is a 

 curious fact that von Siebold and Buerger failed to get specimens 

 outside of Kiusiu. It is, nevertheless, rather common in Hondo; thus 

 specimens are recorded from Yokohama, Tokyo, Simoda, Oshima, 

 and the region around Hakone Lake. Yezo specimens are also in 

 various museums, and our National Museum has a fine one from 

 Sapporo, Yezo, thanks to the kindness of Doctor Nozawa. 



Dr. Hugh M. Smith collected a fine series of specimens both at 

 Yamagawa, at the entrance of the Bay of Kagoshima, Kiusiu, as well 

 as near Kochi, on the southern coast of Shikoku, the first record from 

 this island. 



Four specimens (U.S.N.M. Nos. 34179 to 341S3), absolutely indis- 

 tinguishable from those collected near Yokohama, are labeled by 

 Mr. Owston, from whom the National Museum recent!}" acquired 



o Since wi'iling the above I have had an opportunity to examine the type specimens 

 of T. holsti, thanks to the kindness of Doctor Boulenger. This examination substan- 

 tiates what is said above, and Doctor Boulenger agrees now with me that the speci- 

 mens do not represent a separable form.
