Habitat. Formosa and Pascadores Islands. 
T. formosanus is very closely allied to T. septentrionalis, differing in the presence 
of 6 series of large plates along the back instead of 4, and by the frequent presence 
of ro series of ventral plates instead of 8. The size is smaller and the green colour is 
absent from the sides. I am convinced that Van Denburgh’s proposal to separate 
this species into two, one with normally two femoral pores (7. formosanus), the other 
with one (7. stejnegert) is untenable, the general agreement being too great and the 
supposed. distinctive characters too slight and too inconstant to justify such a course.

Body scarcely depressed. Head about 13 times as long as broad, its depth 
equal to the distance between the centre of the eye and the tympanum, its length 
| This specimen was received from the Museum of the California Academy under the name of 7. stejnegeri. Vet in 
his description Van Denburgh refers all the specimens trom Kanshurei to T. formosanus, thus showing the uncertainty 
in distinguishing the two supposed species. The author rightly observed that unfortunately no one of the distinctive 
characters is absolutely constant in all specimens.
