larger number of subdigital lamellae on the fourth toe — 17 to 22, 

 averaging 19.7 in 33 examples. The two Jamaican species show a 

 variation of 12 to 15 for occiduus and 13 to 18 for impressus. 



It cannot be doubted, however, that costatus is related to the 

 Jamaican occiduus. The coloration is practically identical in both 

 species. The middorsal light area with its dark bordering stripes is 

 particularly prominent in most of the Hispaniolan costatus and extends 

 sometimes almost as far back as the hindleg. The proportions of 

 length to width in costatus also approach occiduus, rather than the 

 blunt-headed impressus.
