number ; when more than three are present, it is usually because one 

 or more of the original scries has longitudinally divided. The first of 

 the series are usually in contact, but the third is usually separated 

 from the second by the second prefrontals which are in contact. There 

 are 70 to 82 dorsal scales between the occiput and the beginning of the 

 tail, and from 16 to 20 dorsals in the distance from snout to the 

 occiput. The adpressed hind leg reaches to the center of the eye or to 

 its anterior corner in adults ; in the very young male it reaches nearly 

 to the nostril. The subdigital lamellae of the fourth toe number from 

 25 to 29. The tail when perfect is about one and three-quarters times 

 the length of the head and body. 



In coloration the variation between the sexes is at once apparent. 

 The males have the very distinct square black patches on the shoulder 

 region, with a sudden diminution in the intensity of these blotches both 

 dorsally and posteriorly, so that they can hardly be discerned. The 

 females, on the contrary, lack the black color entirely, the four rows of 

 quadrangular blotches on back and sides being uniformly sepia, as are 

 the transverse latero-ventral stripes, which in the males are so hand- 

 somely edged with scarlet vermilion. The very young male has a 

 brilliant pattern of black blotches which appears even on the tail as 

 widely spaced bars ; on the middle of the back, however, the blotches 

 are already beginning to lose their intensity and fade out gradually. 



Dr. Noble has given additional notes on color and habits in his recent 

 paper. 



Relationships. — From the West Indian islands five species of 

 Leloce phalli s with a lateral fold have been described up to the present 

 time. They are schreibersii and melanochlorus from Hispaniola, 

 raviceps and macropus from Cuba, and loxogrmmmis from Rum Cay 

 in the Bahamas. The new species from Great Inagua Island makes the 

 sixth belonging to this group. It is intermediate in the size of its 

 scales between melanochlorus, the largest-scaled species, and the other 

 four known species, all of which have rather small scales. In color- 

 ation it suggests loxogrammus somewhat in the presence of the black 

 blotches on the sides of the neck, but otherwise the patterns are not 

 alike. It is true that melanochlorus has four sets of blotches on back 

 and sides, as does inaguae, but in adult males of the former species 

 those above the shoulder are not more prominent than those elsewhere 

 on the body. 



The prefrontals of loxogrammus are vastly different from those of 

 the new species — the prefrontals of loxogrammus being only two in 

 number, the posterior ones very large and elongate. Practically this 

 same arrangement is found in raviceps of Cuba. In macropus of
