and the derm appears as if composed of nicely fitted plates riveted 

 together, so remarkable is the arrangement of small pores around the 

 margins of the plates. The entire derm is full of pores of various 

 kinds. 



Newstead described a supposedly new species, called perforatum 

 on account of a series of ten rather large pores in some of the posterior 

 submarginal plates, which Signoret failed to mention in his descrip- 

 tion of tessellatus, a character which might easily have been omitted 

 among the other more remarkable characters of this species. There 

 are specimens of this species in the Fitch Collection at Washington 

 from Signoret, and these all show the "perforations." The writer 

 has examined hundreds of specimens of this species and all exhibit 

 this same character. 



Green in 1904 described from Ceylon, as suhtessellatum, what he 

 considered a new species, because the specimens he had at hand were 

 apparently immature and lacked the strong tessellation in the mid- 

 dorsal region. Later Mr. Green has recalled the species after exam- 

 ining a larger series of these scales, and considers the above synonymy 

 as correct.
