much paler because of the great reduction in the size and intensity of 

 the spots. The hiteral stripe on the flanks and tail is quite prominent. 

 Rclationshi/^s.— 'This species falls in the key near to corticolus and 

 argiis. It differs from corticolus, however, in having the traces of 

 crescentic grooves on the rostral, while its keeled throat scales serve 

 to distinguish it from argits, as well as from barlschi, one of the other 

 new forms described in this paper.

A young individual, apparently a female, U.S.N.M. no. 79061 from 

 Diamond Hill, South Martinique, taken August 9, 1929, shows a 

 characteristic pattern of light chevron-shaped markings across the 

 back. 



I shot 16 lizards, mostly tree-climbing, but I got a small dark fellow under 

 the muck and rubbish, probably a young one Diamond Hill is a coni- 

 cal eminence rising quite abruptly to an elevation of 1,568 feet. It is rough and 

 rocky near the summit, and in spots carries still a bit of woods. Very little of 

 living stuff was found but we did get a splendid lot of muck and rubbish adding 

 many things to our catch of yesterday.

Diagnosis. — Dorsals imbricate, elongate, keeled ; no dififerentiated 

 middorsal zone ; scales of middorsal region very slightly smaller than 

 those of flanks, about 13 middorsals and about 11 dorsolateral scales 

 in the standard distance between tip of snout and center of eye ; supra- 

 nasals large, normal, separated by one small scale ; a more or less 

 distinct crescentic groove on each side of median rostral groove ; ven- 

 trals smooth ; anterior gular scales faintly keeled ; head relatively short 

 and broad, body heavily built, size relatively large. Sexual dichroma- 

 tism scarcely evident ; males usually rather faintly spotted above, 

 females somewhat more heavily spotted, both sexes with a more or 

 less distinct light-centered, dark-edged nuchal crescent and several
