THE HERPETOLOGY OF HISPANIOLA 191 



"Paratypes. — Another example of this interesting new form, M.C.Z. 

 37524, accompanied the type specimen, having been given to Dr. 

 Barbour by Monsieur Audant. Two additional specimens, which 

 are the property of the museum at the Agricultural School at Port- 

 au-Prince, have recently been sent to me by M. Audant for examina- 

 tion. In 1927 Dr. A. Wetmore secured four which unfortunately 

 reached the National Museum in poor condition. These are U.S.N.M. 

 72593-4 from the head of Riviere Chotard, and U.S.N.M. 72598-9 

 from Morne Cabaio, both localities in Massif de la Selle. An im- 

 mature individual, now U.S.N.M. 85008, was taken also on Morne 

 La Selle at 7,000 feet by Lt. Comdr. S. S. Cook in 1932. 



"Variation. — With a series now numbering nine individuals, some 

 attention may by given to variation. The keeling of the supraocular 

 disks may be distinct, faint or absent. The supraorbital semicircles 

 are fully in contact in four cases, barely touching in one case and sepa- 

 rated by a row of scales in four cases. The number of loreal rows is 

 4 in one case, 5 in six cases, and 6 in two cases. The lowest loreal row 

 extends backwards, completely separating the subocular from the 

 upper labials in four examples; the separation is partial in one in- 

 stance, and the lowest loreal row stops anterior to the subocular in the 

 remaining four. There may be 5, 5}i or 6 upper labials to a point 

 beneath the center of the eye. The lamellae under the fourth toe 

 vary between 27 and 31. In three of the lizards the longitudinal fold 

 is the more apparent, partly or almost completely obscuring the 

 transverse fold. In one, the transverse and the longitudinal folds are 

 both equally prominent. In one specimen, the type, the transverse 

 fold is by far the more apparent. The other four examples, including 

 the two males, were too badly preserved in the region of the throat to 

 show any characters there. The degree to which either the longi- 

 tudinal or the transverse fold shows apparently depends a great deal 

 on the preservation. 



"The two males (U.S.N.M. 72593 and 72594), having a pair of 

 prominent, enlarged postanals, measure 44 mm. and 59 mm. respec- 

 tively from snout to vent. The five females are between 43 mm. and 

 50 mm.; while the two young specimens without enlarged postanals 

 (U.S.N.M. 72599 and 85008) are 36 mm. and 37 mm. respectively 

 from snout to vent. 



"The verticils on the tail are only slightly apparent in any of the 

 specimens. Each verticil is composed of a straight vertical row of 

 somewhat enlarged and more regular scales, preceded by four or 

 five very irregular curving and sometimes incomplete rows of scales. 



"The four transverse sets of two or three dark rhombic or quad- 

 rangular spots on each side of the mid-dorsal region are evident in 

 most of the specimens. In two, the spots are reduced to several 

 narrow, elongate, dumbbell-shaped marks which join across the back,
