THE HERPETOLOGY OF HISPANIOLA 139 



behind the occipital. Sometimes the dark lateral vermiculations 

 form a triangular pattern, the apex of each triangle pointing toward 

 its fellow of the opposite side, the bases forming a continuous dark line 

 delimiting the light lateral stripe on its upper border. There is 

 frequently a wide brown stripe on the anterior part of the forearm, 

 and another on the posterior surface of the hindleg. Below the light 

 lateral stripe there are sometimes a few very small black spots. The 

 head in all cases is immaculate except for the black postoccipital 

 markings. Females have no gular fan or enlarged postanals. In 

 life the scales of the gular fan range from yellow to orange and brick 

 red, while the gular skin is often deep maroon-red. On a freshly collected 

 example from San Michel (U.S.N.M. No. 74135) the skin of the gular 

 fan was Indian yellow, becoming dark clay color toward the body, 

 while the scales adorning it were pale cream color. The tail behind 

 the vent was salmon color, while a very light tint of this suffused the 

 sides in front of the groin. Another male from the same place (U.S. 

 N.M. No. 74136) was similar but darker, the gular skin being dark 

 salmon on its distal edge, becoming dark olive-green nearest the throat. 



The maximum size (U.S.N.M. No. 74149, an adult male from San 

 Michel) appears to be 43 mm. for head and body, the tail being 133 

 mm. long or over three times the length of head and body combined. 

 This proportion is quite constant, as in those examples having the 

 entire tail the head and body together measured from 21.3 to 28.7 

 percent of the total length. 



In only two out of my large series of lizards were the supraorbital 

 semicircles in contact; in all others they were separated by one row of 

 scales. Loreal rows number 3 to 5, with 4 by far the most frequent. 

 The enlarged dorsal rows vary from 10 to 12 in number. 



There may be one, two, or three scales separating the supraorbital 

 semicircles from the occipital shield. The supraocular disk is some- 

 times in contact with the supraorbital semicircles but much oftener 

 separated by a single row of small scales. 



With some doubt I place with Anolis olssoni a single adult male 

 (U.S.N.M. No. 62103) collected by Dr. W. L. Abbott in the liills 5 

 miles south of Constanza. Tliis individual has much smaller scales 

 on the gular fan than does typical olssoni from San Michel, Haiti. It 

 does not approach semilineatus, however, in fineness of scales. In 

 fact, while the gular scales are finer, the dorsal and ventral scales of 

 the Constanza lizard are actually perceptibly coarser than they are in 

 the San Michel specimens. The color pattern of this Constanza 

 specimen shows none of the definite black markings that so often 

 appear on true olssoni. It is lilac-gray above, tinged with china blue 

 on the supraocular region; the dorsal tone shades into drab above the 

 lateral light stripe, which is very sharply marked anteriorly but less 

 so after it passes the shoulder, back of which it fades out almost
