REPORT OF NATIONAL MUSEUM, 1898. 



of the P. d. ornatissimum is very short, but in the male it is sometimes 

 more than half the length of the head and body, as in P. hernandesi. 

 The typical coloration consists of dark -brown spots surrounded by a 

 yellow border on the dorsal region, but the yellow border may be 

 visible on the posterior side of the spot, as in P. hernandesi. The spots 

 may also extend to the sides, as in that form I do not find the differ- 

 ences in the form of the head to be constant, although in typical forms 

 that of the P. d. ornatissimum is more obtuse than in the P. d. hernandesi.
