 Douwing formose. Rcnard. 1 . pi. 5.f. 34. 



SLIGHTLY described by Cepede, from the suspici- 

 ous authority of Renard : it is named from the 

 geometrical regularity of its pattern, which on a 

 dusky ground exhibits on each side of the body 

 seven or eight concentric white circles, of which 

 the three or four interior are complete, the rest 

 more or less broken : the head is streaked with 

 various lines of the same colour. Native of the 

 Indian seas.
