Description. — Adult male; Science College Museum, Tokyo, No. 

 5; Taipa, Formosa; December, 1897; T. Tada, collector (figs. 

 266-268). Rostral about one-third wider than high, largely visible 

 from above; internasals longer than broad, nearly as long as pre- 

 frontals, the latter broadly in contact with supraocular; frontal con- 

 siderably longer than wide, longer than its distance from rostral, but 



a Signifying keeled ; with reference to the strong development of the keels of the scales.
